  iOS & iPadOS 26.2 Beta Release Notes

  Apple releases the iOS and iPadOS 26.2 SDK with Xcode 26.2 for beta app development and API testing. It includes fixes for allocations reporting, StoreKit testing subscriptions, and subscription status, plus guidance on TLS Client Hello changes.

  iOS & iPadOS 26.2 SDK

  The iOS & iPadOS 26.2 SDK provides support to develop apps for iPhone and iPad running iOS & iPadOS 26.2 beta. The SDK comes bundled with Xcode 26.2, available from the Mac App Store. For information on the compatibility requirements for Xcode 26.2, see Xcode 26.2 Release Notes.

  Fixed

  • The Allocations instrument sometimes fails to report reference counting operations for native Swift types. (163080666)
  • PermissionKit Significant App Update API is not testable in sandbox. (163601229)
  • Fixed: An issue prevents the purchase of a subscription using a win-back offer when testing with StoreKit Testing in Xcode. (162357552) (FB20604848)

  SubscriptionStatus

  • SubscriptionStatus.all returns old SubscriptionStatus after a subscription change. (163505178)
  • Workaround: Wait 24 hours and try again.

  TLS Client Hello

  The default TLS Client Hello has been modified. If your app or website communicates with servers configured with strict bot-detection or security policies that only allow traffic with known TLS fingerprints, then users might be unable to login or perform other actions.
  TLS Client Hellos are expected to change across releases as Apple works to offer the most secure TLS options. Servers should adopt resilient and adaptable bot-detection policies that can handle changes in TLS Client Hellos. Overly restrictive policies can cause difficult to triage disruptions to user experience. (163151032)

  AppKit Release Notes for macOS Monterey 12

  MacOS Monterey 12 AppKit brings new button tinting, slider track fills, and layered SF Symbols for richer in‑window UI. It adds animations for popovers, enhanced symbol configuration, and tightened secure coding for restorable state, plus broader API changes.

  New Features

  NSButton

  • Buttons no longer highlight using the accent color when clicked. Before using any subclass that performs custom drawing, inspect the button cell’s doc://com.apple.documentation/documentation/appkit/nscell/1526141-interiorbackgroundstyle property to determine if the bezel draws in a normal or emphasized state.
  • Buttons now support custom tinting with the bezel Color property. This property — previously applied only in the Touch Bar — now functions for all in-window buttons using the doc://com.apple.documentation/documentation/appkit/nsbuttontype/nsbuttontypemomentarypushin style.

  NSSlider

  • When clicking on the track, for linear sliders, circular sliders, or dial, the slider now animates to the new value.
  • You can now tint sliders with colorful track fills using the track Fill Color property. This property now functions for all in-window sliders.

  NSSegmentedControl

  • Segmented controls now support custom tinting via the selected Segment Bezel Color property. This property now functions for all in-window segmented control styles that draw colorful selected segments.

  NSPopover

  • NSPopover has a new animation when appearing and dismissing.

  Symbol Images

  • SF Symbols now support layered symbol images. Layered symbol images use an updated data format to annotate each path element of the symbol with a level in a hierarchy: primary, secondary, tertiary, and so on. At draw time, AppKit can assign different colors to each layer of the symbol using new APIs on NSImage .Symbol Configuration. Many system-provided symbol images redesigned to include layered versions.
  • NSImage .Symbol Configuration now supports merging two configurations with applying(_) method.
  • NSImage now includes a read-only property, NSImage .Symbol Configuration, for its current symbol configuration. You can use this property to configure other symbol images to match a reference image, or to merge an image’s existing configuration with a set of new configuration options.

  Restorable State

  • To enable secure coding for a restorable state, implement application Supports Secure Restorable State(_:). When opted in:
    • The system requires classes passed to restoration Class to explicitly conform to NSWindow Restoration.
    • Set requires Secure Coding to true and the decoding Failure Policy to NSCoder .Decoding Failure Policy .set Error And Return for any coder the following implementations or overrides use decoding Failure Policy set to NSCoder .Decoding Failure Policy .set Error And Return:
      • restore Window(with Identifier: state: completion Handler:)
      • restore Window(with Identifier: state: completion Handler:)
      • encode Restorable State(with:)
      • encode Restorable State(with: background Queue:)
      • restore State(with:)
      • restore Window(with Identifier: state: completion Handler:)
      • encode Restorable State(with:)
      • encode Restorable State(with: background Queue:)
      • restore State(with:)
    • Additionally, restorable State Key Paths must only point at NSSecure Coding-compliant values and you need to implement allowed Classes(for Restorable State Key Path:) to specify the type of the object.

  NSMenu

  • The new user preference “Automatically hide and show the menu bar in full screen” in Dock & Menu Bar preferences is enabled by default. In macOS Monterey 12, the user can choose to disable this setting to always show the menu bar in full screen spaces. Standard full screen windows are resized to fit below the menu bar. Some apps assume a full screen-sized window, and don’t work well with this setting.

  NSTableView

  • 20-point spacing precedes each group row to make the separation between sections more visible. Source lists have a similar, but smaller, 13-point spacing. This applies to the NSTable View .Style .inset and NSTable View .Style .full Width effective styles in apps linked against the macOS 12 SDK. NSTable View .Style .plain doesn’t display the spacing.
  • The floating group row transition — previously a push transition — instantly replaces the new floating group row. It occurs when the x-height of the group row’s label meets the bottom of a currently floating group row.

  NSOutlineView

  • The disclosure button now aligns with the cell view’s first Baseline Offset From Top. The system overrides it in NSTable Cell View so it matches the baseline of its text Field (assuming textfield sets the baseline). Overriding the property and returning 0 reverts to the previous behavior.
  • When collapsing several items, the selection Did Change Notification only posts once. Previously, it posted once per collapsed item.

  NSOpenPanel

  • Setting can Choose Files to false automatically disabled files, but all of the directory contents were sent to panel(_: should Enable:) or panel: should Show Filename:. In macOS Monterey 12, files aren’t sent to the delegate methods unless can Choose Files is true. In addition, file packages are excluded unless treats File Packages As Directoriesis is true. This change allows optimization in the delegate method.

  TextKit 2

  • TextKit 2 introduces a new text layout engine and its associated API. You can use TextKit 2 alongside the existing TextKit API.
  • NSText Content Storage and NSText Layout Manager are the two main controller objects superseding NSText Storage and NSLayout Manager respectively. NSText Paragraph managed by NSText Content Storage represents a paragraph of text. NSText Layout Manager stores the layout information in its model objects: NSText Layout Fragment and NSText Line Fragment.
  • In TextKit 2, NSText Selection encapsulates information associated with a text selection while NSText Selection Navigation manipulates and converts the selection object based on keyboard and mouse navigation actions.

  AppKit Release Notes for macOS 14

  Apple macOS 14 AppKit update brings major API changes and deprecations, including EPS removal and new view clipping defaults. The release introduces new APIs for views, toolbars, menus and activation, plus guidance to test apps against API changes.

  NSEPSImageRep

  • Deprecated in macOS 14.0 as encapsulated PostScript (EPS) files are no longer supported by macOS. Learn more on Apple Support. (107052479)
  • Attempting to initialize an instance of NSEPSImageRep will always return nil on macOS 14.0 and later.
  • Attempting to initialize an instance of NSImage with an EPS file or data will always return nil on macOS 14.0 and later.
  • If a multi-rep image is initialized by name (NSImage(named:), Bundle.image(forResource:), etc.), it will no longer include EPS reps. If no supports (non-EPS) reps could be produced, this will result in nil being returned from these functions.

  NSImageDelegate

  • Deprecated four of the five NSImageDelegate methods as of Mac OS X 10.4 Tiger. (18422088)
  • -image: will Load Representation:
  • -image: did Load Representation Header:
  • -image: did Load Part Of Representation: with Valid Rows:
  • -image: did Load Representation: with Status:
  • These methods haven’t been called by AppKit since Mac OS X 10.4 Tiger.
  • Using these symbols in Objective-C may produce warnings or errors, depending on the project’s build settings.
  • These symbols are no longer available in Swift in the macOS 14.0 SDK.

  NSSavePanel, NSOpenPanel

  • Added the property identifier. (4228269)
  • Modeless and application modal open and save panels are now main windows. (14623155, 103038843)
 This fixes a problem where menu items that weren’t applicable to the open or save panel remained enabled.
Open and save panels that are displayed as sheets are unchanged.
  • Removed the titlebar from modal and modeless NSSavePanels. (105212420)
 This changes NSSavePanel to have consistent behavior with NSOpenPanel.

  NSPrintPanel, NSPageLayout

  • Applications linking against SDKs released for Fall 2023 may now release the NSPrintInfo instance and other related objects as soon as the NSPrintPanel/NSPageLayout panel is dismissed.
  • Added block based variants of the begin-sheet methods (6990600):
    class NSPrintPanel {
    open func beginSheet(using printInfo: NSPrintInfo, on parentWindow: NSWindow, completionHandler handler: ((NSPrintPanel.Result) -> Void)? = nil)
    open func beginSheet(using printInfo: NSPrintInfo, on parentWindow: NSWindow) async -> NSPrintPanel.Result
    }
    class NSPageLayout {
    open func beginSheet(using printInfo: NSPrintInfo, on parentWindow: NSWindow, completionHandler handler: ((NSPageLayout.Result) -> Void)? = nil)
    open func beginSheet(using printInfo: NSPrintInfo, on parentWindow: NSWindow) async -> NSPageLayout.Result
    }

  NSColor

  • NSColor.textInsertionPointColor provides a robust way to get the current text insertion point color as defined by the system.
  • To be consistent with an NSTextView, use NSTextView.insertionPointColor.
  • Otherwise, if not using a text view, use NSColor.textInsertionPointColor.

  NSTextInsertionIndicator

  • NSTextInsertionIndicator is a new NSView that encapsulates all the behavior for a text insertion indicator — such as blinking while waiting for typing and prompting during dictation. NSTextView uses the NSTextInsertionIndicator. But, if using a custom text implementation, instantiate and add an NSTextInsertionIndicator as a subview of the custom text view. Its text implementation only needs to set the indicator view’s display mode—automatic, visible, or hidden—and frame. Based on the display mode the indicator view will infer from the frame whether it needs to blink or not.

  NSView

  • In macOS 14, AppKit is exposing the clipsToBounds property of NSView.

  For applications linked against the macOS 14 SDK, the default value of this property is false. Apps linked against older SDKs default to true. Some classes, like NSClipView, continue to default to true. The change in defaults recognizes that it is vastly easier to reason about clipping a view’s descendants than it is to unclip a view’s ancestors.

  Users can turn clipping back on by using the NSView.clipsToBounds setter or using the attributes inspector of a view in the Xcode interface builder.

  This property is available back to macOS 10.9. This availability is intended to allow code targeting older OSes to set this property to true without guarding the setter in an availability check. Setting this property to false on previous OSes may not work reliably.

  Some patterns that have historically worked will require adjustment:
  ◦ Showing or hiding UI by setting an ancestor’s frame to zero. When attempting to hide a view hierarchy by shrinking the size of an ancestor, or positioning a descendent view outside an ancestors view’s bounds, it is now necessary to set the ancestor’s view’s .clipsToBounds property to true. An alternative may be to set NSView.isHidden, instead.
  ◦ Filling the dirty rect of a view inside of -drawRect. A fairly common pattern is to simply rect fill the dirty rect passed into an override of NSView.draw(). The dirty rect can now extend outside of your view’s bounds. This pattern can be adjusted by filling the bounds instead of the dirty rect, or by setting clipsToBounds = true.
  ◦ Confusing a view’s bounds and its dirty rect. The dirty rect passed to .drawRect() should be used to determine what to draw, not where to draw it. Use NSView.bounds when determining the layout of what your view draws. (10905750)

  NSViewController

  • Added API:
    open var viewIfLoaded: NSView? { get }
    open func loadViewIfNeeded()
    open func present(_ viewController: NSViewController, asPopoverRelativeTo positioningRect: NSRect, of positioningView: NSView, preferredEdge: NSRectEdge, behavior: NSPopover.Behavior, hasFullSizeContent: Bool)
  • NSViewController.loadView() no longer throws an exception when the view controller’s nibName is nil. (81775005)

  TextKit API Coordinate System Changes

  • Applications linking against SDKs released for Fall 2023 have behavior changes from TextKit API.
  • NSTextLineFragment.typographicBounds is relative to NSTextLayoutFragment.layoutFragment.origin (instead of in the text container coordinate system as it was before)
  • NSTextLineFragment.typographicBounds.size.width doesn’t contain NSTextContainer.lineFragmentPadding. The side effect of this change is that the padding is also excluded from both NSTextLayoutFragment.layoutFragmentFrame and NSTextLayoutManager.usageBoundsForTextContainer. Consequently, NSTextLineFragment.glyphOrigin.x no longer includes the padding, either.
  • NSTextLineFragment.locationForCharacterAtIndex() used to return a point relative to NSTextLayoutFragment.origin. It now returns a point relative to the text line fragment coordinate system as documented.

  Restorable State

  • Secure coding is automatically enabled for restorable state for applications linked on the macOS 14.0 SDK. Applications that target prior versions of macOS should implement NSApplicationDelegate.applicationSupportsSecureRestorableState() to return true so it’s enabled on all supported OS versions.

  Display Link

  • A CADisplayLink can be created via NSView.displayLink(target: selector:). The CADisplayLink will automatically track the display the view is on, and will be automatically suspended if it isn’t on a display. A CADisplayLink instance can also be created from an NSWindow or NSScreen.

  NSToolbar

  • Applications linked against the macOS 14.0 SDK will no longer show the .toggleSidebar toolbar item to the leading edge of the inline window title and will instead show relative to its order in the defaultItemIdentifiers delegate method. It is recommended to place this item above the sidebar section of the toolbar as the leading most item of that section so that toggling the sidebar does not move the toolbar item itself. As a reminder, items placed before the .sidebarTrackingSeparator in the defaultItems delegate method will appear above the sidebar in the toolbar. Similarly, the best place for the new .toggleInspector item is above the inspector section of the toolbar as the trailing most item following the .inspectorTrackingSeparator, but it may be placed elsewhere in the toolbar if appropriate.
  • NSToolbar now supports centering items in multiple sections of the toolbar. Use the centeredItemIdentifiers property to specify a set of items and they will be centered in the section they appear in. The set of centered items no longer applies to a single section of the toolbar, but may be used to center one item in the sidebar section and another item in the content section for instance.
  • NSToolbar with autosavesConfiguration enabled and allowsUserCustomization disabled will now persist manual changes to the toolbar from -insertItemWithIdentifier: atIndex: and -removeItemAtIndex: across app launches. Previously manual inserts/removes were not persisted. Additionally, NSToolbars with autosavesConfiguration disabled will now sync manual inserts/removes to other NSToolbar objects with the same identifier, including new windows, but the toolbar’s configuration will not persist across app launches. If syncing across windows is not desired, each window’s toolbar should be given a unique identifier. (103038749)

  Menus

  • In macOS 14, menus have been reimplemented from the ground up to fully use AppKit.
  • New section header API provides a consistent way to organize and structure menus.
  • NSMenu has new selectionBehavior property, which allows the menu to automatically manage state of the same selection groups, reducing the amount of code the developer has to write.
  • Palette presentation style allows to show menu items in a horizontal series, embedded inline in the parent menu.
  • NSMenuItem has new API to create section header menu items, which are used to organize and structure menus. The appearance and behavior of section header items are entirely defined by NSMenu and cannot be customized. (59962793)
  • For applications linked against the macOS 14 SDK, NSMenu will now assert if a secondary thread inserts or removes menu items from menus contained within the main menu. Making changes to the main menu from any thread other than the main thread has never been a supported or safe programming practice, because the main thread may be examining the main menu contents at any time (for example, to draw the menubar, to determine if a menu item matches a key event, to answer an accessibility request, etc), and there is no method for a background thread to modify the main menu while ensuring that the main thread is not simultaneously examining its contents. This practice is now prevented at runtime. (96331659)

  App Activation

  • In macOS 14, app activation is driven by user intent. It is treated by the system as a request and is not always guaranteed to be honored or to succeed. Apps have the ability to provide context with activation requests in cases where a more deterministic result is desired.
  • NSApplication.activate(ignoringOtherApps:) and NSApplication.ActivationOptions.ignoringOtherApps are deprecated in macOS 14 and should not be used.
  • NSApplication has a new method, activate, that sends the activation request to the system. The request may provide different results based on the context in which the app is running, user activity, and other factors. If necessary for app functionality, active status can be checked by querying the isActive property on NSApplication. In general, apps should not assume that activation requests will always succeed.
  • macOS 14 provides more ways for apps to express the context in which activation should occur. A common scenario is cooperative activation, or passing the active state from one app to another. This process can be useful for apps that need to explicitly pass activation state, such as launchers and view services. The active app can use NSApplication.yield(to:) method to yield its active state to an instance of NSRunningApplication, or yield(toApplicationWithBundleIdentifier:) to yield to a bundle ID, which may be used in case the receiver app is not running or its status is unknown. Note that the sender does not deactivate at the time of invoking these methods. After yielding, the sender may activate the receiver using NSRunningApplication API, or the target app may simply activate itself by invoking the NSApplication.activate method. The cooperative activation mechanism guarantees successful activation as long as the yielding app is active at the time of the request and the receiver can become active.
  • Existing calls to NSApplication.deactivate() should be replaced by NSApplication.yield(to:) to make activation handoff more explicit, and to delay changing the appearance of the calling app until the target app has activated.

  • Workaround: Change the files to proper owner using Recovery and chown 0: 0 /etc/sudoers.

  SwiftUI

  Resolved Issues

  • Fixed: The navigation Link Indicator Visibility modifier crashes when run on iOS 17, iOS 18 and aligned releases.
    You must recompile your app against the 26.1 SDK to receive this fix. (158236264) (FB19613386)

  macOS Tahoe 26

  macOS Tahoe 26 SDK launches with Xcode 26, enabling apps for Tahoe 26 and bringing features like Recovery Assistant, Foundation Models, Accessibility labels in App Store, Sparse Image support, and various Catalyst, Metal, and SwiftUI updates. It also deprecates AGL, updates many subsystems, and fixes numerous issues across Finder, Photos, Messages, and more.

  Overview

  The macOS 26 SDK provides support to develop apps for Mac computers running Tahoe 26. The SDK comes bundled with Xcode 26, available from the Mac App Store. For information on the compatibility requirements for Xcode 26, see Xcode 26 Release Notes.

  General

  New Features

  • Recovery Assistant is a new way to recover your device if it doesn’t start up normally. It can look for problems and attempt to resolve them if found. (151856202)

  AGL

  Deprecations

  • AGL is no longer available in the macOS SDK. AGL was previously used to present OpenGL content in Carbon apps, and Carbon no longer exists in the SDK. AGL symbols now do nothing on 64-bit systems, including Intel x86_64 and Apple Silicon Macs. It is safe to remove any AGL usage and stop linking AGL. OpenGL still remains in the SDK. (153913819)

  AirPlay

  Known Issues

  • AutoMix song transitions might not work as expected when streaming with AirPlay. (155925891)

  App Store

  New Features

  • A new Accessibility section has been added to the App Store product pages that highlights accessibility features within apps and games. These Accessibility Nutrition Labels give users a new way to learn if an app will be accessible to them before they download it, and give developers the opportunity to better inform and educate their users on features their app supports. (138344118)

  Resolved Issues

  • Fixed: Updating iOS or iPadOS apps on macOS from the App Store might hang with a spinning progress indicator or with the progress partially complete. (152878930)

  AppKit

  Resolved Issues

  • Fixed: With TextKit, the text Range By Intersecting With Text Range method in NSTextRange does not return nil for non-intersecting ranges. (138067979)

  Apple Intelligence

  New Features

  • The Foundation Models framework provides you with direct access to the on-device large language model at the core of Apple Intelligence. For release notes about the framework, see the Foundation Models framework section below. (139996377)

  Resolved Issues

  • Fixed: In Image Playground and Genmoji, the new modifiers to customize appearance do not work for Japanese-language users. Image creation is blocked when attempting to add modifiers to its appearance. (151833204)
  • Fixed: Model quality output degrades after extended, repeated inferences of the same adapter. (152468267)

  Known Issues

  • Xcode features like Predictive Code Completion and the coding assistant might require Apple Intelligence to be enabled. (150889516)
    Workaround: Enable Apple Intelligence in System Settings.

  AssistantSchemas

  Resolved Issues

  • Fixed: If you have adopted any of the following email AssistantSchemas, you will experience a compilation error due to a parameter type change: create Draft, update Draft, reply Mail, forward Mail, message, and draft. (148633307)

  AuthenticationServices

  New Features

  • ASAuthorizationControllerRequestOptions.preferImmediatelyAvailableCredentials now works for passkey registration requests. This request only shows UI when the device is immediately able to create a passkey; otherwise, no UI is shown. (150688929)

  AVFoundation

  Resolved Issues

  • Fixed: AVPlayerLayer does not ensure a valid video frame is always displayed during item replacement, as the isReadyForDisplay property does not remain true during transitions. (151902458)

  Background Assets

  Resolved Issues

  • Fixed: The system might not update downloaded asset packs as frequently as is expected for apps that internal testers install from TestFlight. (143281558)
  • Fixed: Asset pack downloads might fail unexpectedly or stall indefinitely, including across reboots. (151498902)
  • Fixed: The system might not deliver status updates to your app for ongoing asset pack downloads. (151647839)
  • Fixed: An iOS or iPadOS app on an Apple silicon Mac might appear openable in TestFlight even while its essential assets are still being downloaded. (151709449)
  • Fixed: Pausing and resuming an app installation or update while the system is downloading essential asset packs might cause the installation or update to stall indefinitely. (151942388)
  • Fixed: The installation of large asset packs might fail. (153128086)

  Catalyst

  New Features

  • For Catalyst apps built with the latest SDK, UINavigationItem.title is the window title rather than the window subtitle. (142423319)
  • For Catalyst apps built with the latest SDK, UIBarButtonSystemItem.fixedSpace and .flexibleSpace are now bridged to NSToolbar. The system no longer ignores fixed and flexible spaces when UIBarButtonItems are automatically converted to the window toolbar in the Mac idiom. However, the width specified via fixedSpaceItem(ofWidth:) is ignored. (145262754)

  CloudKit

  Resolved Issues

  • Fixed: CloudKit sharing URLs do not launch third-party apps. (151778655)

  Contacts

  Known Issues

  • Characters for Monogram Avatars in some non-English languages might show up as unexpected symbols. (154824077)

  CoreData

  Resolved Issues

  • Fixed: In beta 5 SDK, CoreData changed several Sendable annotations to resolve compatibility issues with Swift 6’s new MainActor default isolation feature. These changes include marking NSManagedObject as NS_SWIFT_NONISOLATED NS_SWIFT_NONSENDABLE, marking NSManagedObjectContext as NS_SWIFT_NONISOLATED NS_SWIFT_SENDABLE, and requiring NS_SWIFT_SENDABLE closures for the family of perform, performBlock, performBlockAndWait and similar methods. These changes are ABI compatible with past releases but might introduce new warnings while building source code that violates the longstanding CoreData concurrency guidelines.

  • NSManagedObject are mutable reference types inextricably related to others in a graph and cannot be made Sendable. They are expected to be isolated to the scope of the NSManagedObjectContext that creates or fetches them.

  • NSManagedObjectContext is a style of actor which encapsulates its own dispatch queue. While it’s impermissible to use many methods on NSManagedObjectContext from other threads, it is permissible to pass references around to invoke the performBlock family of methods, for the purpose of routing a Sendable closure to its managed dispatch queue. CoreData supports a user default -com.apple.CoreData.Concurrency.Debug 1 which can be used to enable additional assertions. (153848710) (FB18216198)

  Deprecations

  • This release removes support for the following deprecated NSPersistentStore option keys:
    ◦ NSPersistentStoreUbiquitousContentNameKey
    ◦ NSPersistentStoreUbiquitousContentURLKey
    ◦ NSPersistentStoreUbiquitousPeerTokenOption
    ◦ NSPersistentStoreRemoveUbiquitousMetadataOption
    ◦ NSPersistentStoreUbiquitousContainerIdentifierKey
    ◦ NSPersistentStoreRebuildFromUbiquitousContentOption
    These keys have been deprecated for more than a decade. Affected apps rebuilt with the iOS or macOS 26 SDK will get errors. Apps built against older SDKs will log warnings when opening the store.

  • The on-device persistent store will be fully usable after these keys are removed from options dictionary, albeit without syncing. For data syncing, these APIs were superseded by NSPersistentCloudKitContainer in iOS 13 and SwiftData in iOS 17. If absolutely necessary, the iCloud content remains accessible in the containers with the last baseline as a .zip archive file. (157297746) (FB19286235)

  Disk Images

  New Features

  • macOS now supports the Apple Sparse Image Format (ASIF). These space-efficient images can be created with the diskutil image command-line tool or the Disk Utility application and are suitable for various uses, including as a backing store for virtual machines storage via the Virtualization framework. See VZDisk Image Storage Device Attachment. (152040832)

  Documents

  Known Issues

  • EPUB files are shown with an app icon rather than a document icon. Other document types might also be affected. The icon shown is the icon of the app set to open the document. The document opens normally. (154800649)

  Finder

  Resolved Issues

  • Fixed: Finder does not display Dark Mode app icons or tinted folder colors when the Folder Color setting in System Settings > Appearance is set to Automatic. (152193702)

  Known Issues

  • Users who enable path bar or status bar in Finder and use list view might be unable to access the last item in the list. (151917092)
    Workaround: Disable path bar or status bar temporarily.

  Foundation

  New Features

  • Interpolating non-localized types into a LocalizedStringResource/String(localized:)/AttributedString(localized:) value will now display a deprecation warning instead of potentially falling back to a fully-unlocalized string. Provide a localized value to interpolate into the text instead, or silence the warning by wrapping the unlocalized value in a call to String(describing:). (126876158)
  • ISO8601Format Style now allows fractional seconds, regardless of the setting of includingFractionalSeconds. Additionally, ISO8601Format Style now allows hours-only time zone offsets. (136950769)

  Resolved Issues

  • Fixed: Functions that initialize a string from a C-string pointer do not validate that the provided encoding is a valid encoding for C-strings. (143756086) (FB16417968)

  Foundation Models framework

  New Features

  • LanguageModelSession.prewarm() now caches the instructions and prefix of your prompt, in addition to loading system resources. The best place to use prewarm() is when your app is waiting for user interactions that might trigger response generation. This will reduce the time to the first-generated token. (152381043)
  • #Playground in Xcode now allows for filing feedback for Foundation Models framework responses. (153770707)
  • The .contentTagging use case now supports non-English languages. You can query the supported languages using SystemLanguageModel(useCase: .contentTagging).supportedLanguages. Tags will be generated based on the language of the prompt. (155801948)
  • When you use guided generation, the framework now supports programmatically detecting when and why the model refuses to respond when the content is not unsafe. In previous beta releases, this manifested as a guardrail violation. Now you can catch a specific error case LanguageModelSession.GenerationError.refusal and obtain a model-generated explanation for why it refused to respond. Depending on your use case, you might be able to display the explanation in your UI. (156086748)
  • In GeneratedContent, you can use the isComplete property to check whether the content was fully generated by the model. (156109416)
  • When using guided generation, you can now access the underlying weakly typed GeneratedContent by accessing the rawContent property on Response or ResponseStream. (156351123)
  • New guardrails mode Guardrails.permissiveContentTransformations allows transformations of content that might otherwise violate the default guardrails. Use this mode for text-to-text tasks, such as summarization and rewrite. (156721060)

  Resolved Issues

  • Fixed: When you pass includeSchemaInPrompt: false to respond or streamResponse, it is not respected. (151926006)
  • Fixed: Custom @Generable types named Number or Boolean might not function reliably in guided generation. (152280144)
  • Fixed: Tool calling might not function properly if primitive types such as Int, String, or Bool are used as the argument. (152318534)
  • Fixed: In an Xcode Playground, requests made to the model might receive a “rate limit exceeded” error. (152325506)
  • Fixed: Model requests in macOS command line tools might experience rate limiting. (152681332)
  • Fixed: Generable types with a recursive definition lead to a SchemaError when generating a response. (153147722) (FB17962270)
  • Fixed: A prompt containing Chinese might lead to error “Unsupported language zh-hans detected”. (153151710) (FB17963656)
  • Fixed: Generable types cannot be made public due to a bug in the Generable macro. (153216183) (FB17990794)
  • Fixed: Requests to the model might experience rate limiting, even when the device is connected to power. (153216632)
  • Fixed: The Foundation Models framework cannot be imported when building for Mac Catalyst. (153255533) (FB18004324)
  • Fixed: Creating a LanguageModelSession with tools that have duplicate names leads to a fatal error. (153426645) (FB18074984)
  • Fixed: When using guided generation and tool calling together, some requests might lead to LanguageModelSession.GenerationError.decodingFailure due to a bug in constrained decoding. (153773704) (FB18190120)
  • Fixed: When creating a session with a transcript, any new tools you attach to the session might not be used. Additionally, if your transcript contains tools from a previous session, those tools must be passed as the tools: argument in the new session in order to function properly. (154904647)
  • Fixed: Some prompts erroneously return an error indicating a guardrail violation (FoundationModels.LanguageModelSession.GenerationError error 2). (155273863)
  • Fixed: When using tool calling with guided generation, tools might not get called. (155313086) (FB18691470)
  • Fixed: Generating an enum with associated values through a dynamic schema crashes with a SchemaError. (155957346) (FB18878026)
  • Fixed: In some cases, requests you make to the model erroneously throw a guardrail Violation for all prompts due to model assets not fully downloaded. (156223847) (FB18944619)

  Known Issues

  • Some instructions and prompts to the model might not lead to expected responses. Use Feedback Assistant to report satisfactory or unsatisfactory cases. When applicable, you can use LanguageModelSession.logFeedbackAttachment() to serialize the feedback to a JSON file and attach it to Feedback Assistant. (152318091)
    Workaround: Refine your instructions and prompts using #Playground in Xcode. When applying guided generation with a @Generable type, add @Guide with a custom description on properties to steer the model’s responses.
  • If Argument type is an enum with associated type, tools will encounter a ToolCallError with an underlying decoding Failure when the model attempts to call it. (156723065)
    Workaround: Wrap the enum in a struct.

  Full Screen

  Resolved Issues

  • Fixed: You might experience layout issues when going full screen with certain apps on a Mac. (151266898)

  Game Controller

  New Features

  • For supported game controllers, pressing the Home button once opens the Game Overlay. Set preferredSystemGestureState to receive additional Home button press events. (137780853)
  • Pair multiple Apple devices to your DualSense or DualSense Edge controller and easily switch between them directly using the controller or Bluetooth settings. See this PlayStation blog post for details. (137782227)

  Game Mode

  Resolved Issues

  • Fixed: The LSSupportsGameMode Info.plist key is currently ignored on macOS. (153125166)

  Known Issues

  • Game Mode will not activate for application binaries spawned directly from Terminal. (153127050)
    Workaround: Use the open command to launch your game from Terminal. You can pass arguments, change environment variables, and redirect standard output/error when using this command, such as open My Game.app --stdout /tmp/mygame.out --stderr /tmp/mygame.err --env MTL_HUD_ENABLED=1 --args -My Game Argument -Another Argument. See man open for more information.

  Image Playground

  Resolved Issues

  • Fixed: The Create Image action fails to appear in Shortcuts app and Spotlight. (153235442)

  Intel Macs

  Resolved Issues

  • Fixed: Safe and Recovery modes on Intel Macs have performance and graphical issues, though the modes are still functionally usable. Various elements on the screen, such as menus, alerts, and Control Center, might partially display. Scrolling and other operations in some apps cause visual glitches. (149419875)

  Keyboard

  New Features

  • In the “ABC – India” keyboard layout, the ₹ (rupee) symbol has replaced the ` (back tick) symbol. To type the back tick symbol that’s commonly used in Markdown and some programming contexts, you can use the ⌥ (option) modifier in conjunction with the same key or you can use an alternative layout like “ABC”. (149026394)

  Maps

  Resolved Issues

  • Fixed: Users cannot plan a route that leaves at or arrives by a future time. (150947515)
  • Fixed: If you tap to expand the “Recents” section and there are more recent places than can fit in the view, the Terms & Conditions link will disappear, making it inaccessible. (152197565)

  Known Issues

  • Custom tap gesture callbacks registered using onTapGesture might not work as expected on a SwiftUI Map. (157612948) (FB19394663)
    Workaround: Use simultaneousGesture(TapGesture().onEnded {}) to register the callback.

  Memory Tools

  Known Issues

  • Leaks might be falsely reported by memory analysis tools when a target has instances of types that use Obj-C properties implemented in Swift using bridged types with @objc @implementation. Memory analysis tools include the leaks CLI tool, Leaks instrument, and Xcode memory graph debugger. (157798911)

  Menu Customization

  Known Issues

  • Menu customization in apps like Notes and Mail might have some visual glitches. (148472167)

  Messages

  Resolved Issues

  • Fixed: Sent translated messages do not get re-translated after editing. (149401758)
  • Fixed: In regions where Screen Unknown Senders is on by default, notifications for message categories are erroneously off by default. (149450560)
  • Fixed: In one-to-one conversations, background changes might be attributed incorrectly after quitting and re-opening the Messages app. (150548773)
  • Fixed: Transaction or Promotion messages filtered by a Message Filter App Extension might be badged as “Unknown” in the conversation list rather than “Transaction” or “Promotion”. (151869409)

  Known Issues

  • Users on older devices won’t see compatibility messages for polls, so they might be unaware a poll was sent. (148545742)
  • Expanding Conversation Details causes the list of conversations to collapse. (149436051)
    Workaround: Closing Conversation Details will bring back the list.
  • Scrolling through a Messages conversation might be sluggish. (152453655)
    Workaround: Quit and relaunch Messages.

  Metal

  New Features

  • Metal 4 is now supported. See Metal for additional details. (113781091)

  Resolved Issues

  • Fixed: If you’re using Metal 4 command encoders, you should add render and compute pipelines that support indirect command buffers to your residency sets. The Metal device driver currently does not enforce this requirement. (145066238)
  • Fixed: Metal Shader Validation might not work with shaders that use Metal Performance Primitives. (149263281)

  Known Issues

  • Metal Shader Validation might not work with Metal 4 ray tracing pipelines. (152520367)
    Workaround: Selectively disable Shader Validation for pipelines using ray tracing. See documentation.

  MetalFX

  Resolved Issues

  • Fixed: Denoised temporal upscaling for MTL4CommandBuffer’s MTL4FXTemporalDenoisedScaler does not work. (146436460)
  • Fixed: Temporal upscaling for MTL4CommandBuffer’s MTL4FXTemporalScaler does not work. (146436741)

  Music

  Resolved Issues

  • Fixed: You might experience audio issues when using the Music app and changing the underlying audio device sample rate. (152465491)

  NetworkExtension

  Deprecations

  Notifications

  Resolved Issues

  • Fixed: The icons for Calendar notifications might appear washed out. (151658533)

  NSLog

  New Features

  • Dynamic string data in format arguments for NSLog will be redacted to in the Unified Logging System. This specifically targets data that enters the Unified Logging System via NSLog, and will not impact the Xcode console or NSLog’s stdout output. If you wish to log un-redacted data to the Unified Logging System please use the “os_log” or “Logger” interfaces. (137129180)

  NSTextView

  New Features

  • NSTextView supports sound files, such as QuickTime Audio, attached via NSTextAttachment, by utilizing AVPlayer for playback inline. (140224296)

  Object Capture

  New Features

  • A new algorithm significantly improves PhotogrammetrySession reconstruction quality of low-texture objects not captured with the ObjectCaptureSession front end. It will be downloaded and cached once in the background when the PhotogrammetrySession is used at runtime. If network isn’t available at that time, the old low quality model will be used until the new one can be downloaded. There is no code change needed to get this improved model. (145220451)

  Photos / Photos Picker

  Known Issues

  • Invoking search in the Photos picker causes the picker to crash. Or invoking Search in a collection in Photos causes Search to crash. (152403781)
    Workaround: Use the Photos app to search for the content. Once you’ve found it, you can share or copy it to continue with the workflow. Use Search in the Library tab to find the content.

  Photos Picker

  Resolved Issues

  • Fixed: On macOS, the Options menu is missing in the Photos picker. Ability to exclude Location and Captions information cannot be set when using the Photos picker. (152336867)

  Quick Look

  Resolved Issues

  • Fixed: Variants menu does not open in Quick Look while trying to view different configurations of a USDZ asset made with Variants. (154817946)

  RealityKit

  Resolved Issues

  • Fixed: Entities with a PortalComponent ignore any ModelSortGroupComponent and instead use a fixed rendering order.
    In case of sorting rendering issues with portal surface, explicitly add a ModelSortGroupComponent using a .planar UIAlwaysBehind sort group. (149899345)
  • Fixed: ParticleEmitterComponent does not render properly on iOS, macOS, and tvOS. (152201501)
  • Fixed: The animate functions on Entity and RealityViewContent do not start animations. (152456435)

  Known Issues

  • Some properties and components do not update SwiftUI Views when accessed through the .observable property on Entity. (147063698)

  Rosetta

  New Features

  • You can test that your apps no longer depend on Rosetta by setting the boot-arg nox86exec=1. When this boot-arg is set, any process that would normally run through Rosetta will immediately crash on launch and generate a crash report. This can by set by running sudo nvram boot-args="nox86exec=1" and then rebooting the system. (136764433)

  RTL

  Known Issues

  • You might experience layout issues with RTL languages. (151009428)

  Safari

  Resolved Issues

  • Fixed: macOS 26 users might experience Safari page loading issues on facebook.com and potentially other websites, due to a new race in the network stack.
    Affected users should update to macOS 26 beta 5 and clear related cache by visiting Safari > Settings… > Privacy > Manage Website Data…, then deleting entries for facebook.
  • and fbcdn.net resources. Restart Safari. Users will need to re-login to the website. Users experiencing issues on other websites can consider clearing cache for those websites or clearing all website data. (153547547)

  Known Issues

  • Black lines appear at the bottom of inactive tabs in Safari. (153681371)

  Search

  Resolved Issues

  • Fixed: Some applications might quit unexpectedly when using search. The issue will be resolved automatically with an over-the-air update when connected to Wi-Fi. (157464670)

  Secure Text Fields

  Resolved Issues

  • Fixed: On a Mac with a Touch Bar, a secure text field swallows keyboard events in some contexts. For example, this might occur when creating a new user in the Users & Groups settings pane. (151268030)

  Security

  Deprecations

  • For apps linked on or after iOS 26 and macOS 26, the default minimum TLS version of URLSession and Network frameworks has changed from 1.0 to 1.2. If your process connects only to your servers, verify that they support TLS 1.3 or TLS 1.2. If your process needs to connect to 3rd-party servers which cannot be updated to support newer versions of TLS, restore the previous behavior through URLSession and Security framework APIs: URLSessionConfiguration.tlsMinimumSupportedProtocolVersion and sec_protocol_options_set_min_tls_protocol_version. (135996267)

  Settings

  Known Issues

  • Users who enable Reduce Transparency might encounter flickering in background windows or the Dock. (152060485)
  • If System Settings > Desktop & Dock > Displays have separate Spaces is disabled, WindowServer will crash at login time. (153570422)
    Workaround: Boot into Recovery, then mount the Data volume on your partition. Launch Terminal and run rm /Volumes/<Partition Name "Macintosh HD">/Users//Library/Preferences/com.apple.Spaces.plist.

  Setup Assistant

  Resolved Issues

  • Fixed: 802.1X Wi-Fi networks are not saved during initial device setup. (147787689)
  • Fixed: On Intel Macs, the background on the Hello or Welcome screens might be black. (152107967)
  • Fixed: Visual pairing for Quickly Set Up Mac does not work. (152326903)

  Resolved Issues

  • Fixed: Titles for some Messages actions and filter properties display incorrectly. (153740390)

  Siri

  Resolved Issues

  • Fixed: Siri Visual Responses might be illegible behind certain backgrounds. (151682699)
  • Fixed: Knowledge requests that are handled by ChatGPT might produce results that are based on stale data. (154889929)

  StoreKit

  New Features

  • There is a new option for the Transaction.Offer.PaymentMode API called oneTime. This new case supports the method of payment for In-App Purchase offer codes. (142501142)
  • Subscription promotional offers can now be signed using JWS and attached to a purchase using the new PurchaseOption.promotionalOffer(_:compactJWS:) API. There are also new corresponding SwiftUI APIs in StoreKit to attach a signed promotional offer or a signed introductory offer override to a view. (143395736)

  Resolved Issues

  • Fixed: Subscription status updates might not be reported correctly if the subscription went into billing retry in StoreKit Testing in Xcode. (133799135) (FB14789854)
  • Fixed: Price of offers is not displayed in the payment sheet when making a purchase to a subscription with a higher level of service in StoreKit Testing in Xcode. (140635780) (FB15980635)
  • Fixed: Renewal transactions might be created regardless of the Ask to Buy status of the purchase request in StoreKit Testing in Xcode. (145242611)
  • Resolved an issue with the Identifiable conformance of the PurchaseIntent API. Conformance to this protocol now begins starting with iOS 18.0 and macOS 15.0. (148751460) (FB17151889)
  • Fixed: SKProduct from the original StoreKit API fails to decode products when using StoreKit Testing in Xcode. (150851879)
  • Resolved an issue where the id member of the PurchaseIntent API was only available starting with iOS 18.0 and macOS 15.0, and no longer available for Mac Catalyst. It is now available starting with iOS 16.4, macOS 14.4, and Mac Catalyst 16.4. The PurchaseIntent conformance to Identifiable remains unchanged. (152858281) (FB17829716)
  • Fixed: Transactions might not finish, resulting in subsequent purchases of the same product failing. (155449267)

  Swift Charts

  New Features

  • Available in iOS 26, macOS 26, and visionOS 26, Chart3D allows you to visualize your data and mathematical surfaces in 3D, powered by RealityKit. (148361385)

  Resolved Issues

  • Fixed: Annotations on a scrollable chart might be clipped. (109164195)

 (147500528)
  • Fixed: mutating members of MutableSpan and MutableRawSpan are unavailable. (152467655)

  Known Issues

  • lengthOfBytes(using: .utf16) and -lengthOfBytesUsingEncoding: NSUTF16StringEncoding/NSUnicodeStringEncoding might produce an incorrect result when used on Swift Strings, including NSStrings formed by bridging Swift Strings to Objective-C. (156675395)

  SwiftUI

  New Features

  • On macOS, an animated SwiftUI.Transaction that changes a Window’s size animates the window’s frame, alongside the frame of the hosting view. (61158194)
  • You can now use View/findNavigator(isPresented:), View/findDisabled(:), and View/replaceDisabled(:) to control the presentation of the Find Bar in TextEditor on macOS 26. (85308161)
  • ControlSize now conforms to Comparable, and View/controlSize(_:) can now be used to clamp the environment’s controlSize to a given range. (FB11465757)
  • In apps built with the macOS 26 SDK, Section footers within a Form of the Grouped Form Style now have leading alignment, default font, and foreground styles. Use the sectionActions(content:) view modifier on your Section to supply section actions, which maintain a trailing placement in macOS. In iOS and iPadOS, each section action displays as its own form row. (129868475)
  • Text, TextEditor, and TextField now by default use string contents to determine the appropriate base writing direction for each paragraph, instead of relying on layout directionality. To specify the writing direction explicitly on a per-paragraph basis, use Foundation’s AttributedString.writingDirection attribute. To make the base writing direction follow the layout direction for an entire view, apply the view modifier .writingDirection(strategy: .layoutBased). (134821288)
  • In apps built with the macOS 26 and iOS 26 SDKs, a Picker view of a style that produces a button-like control now has a fitted sizing behavior by default. If needed, use the buttonSizing(_:) view modifier to make the Picker flexible and fill the available width of its container. (136649748)
  • The default label style for macOS menu content is now .titleAndIcon. (137306701)
  • The implementation of some macOS buttons no longer uses NSButton. (139105246)
  • When linking news SDKs, NavigationLinks produce a single view, rather than a list of views in view list contexts. This change improves performance of many NavigationLinks in lazy containers like List. However, if you are relying on ContainerValues propagating out of the label view of a NavigationLink, or similarly relying on ContainerValues of a ButtonStyle used to style a link, the containerValue(:,:) modifier should be moved outside of the link. Below is a minimal example that demonstrates the behavior difference: (140283584)
  • List no longer ignores the vertical insets of rows with a height close to the default minimum height on iOS and visionOS. Use listRowInsets(::) to change the vertical row insets. (141160852)
  • In NavigationSplitView and TabViews configured as sidebar Adaptable, the view trailing the sidebar’s safe area is inset in the width of the sidebar. It can display content outside its safe area, underneath the sidebar. (141222137)
  • In macOS, a Form of the .grouped style now has a more compact appearance when placed within a sidebar or inspector. (141534926)
  • Reuse existing AppKit gesture recognizers in SwiftUI using NSGestureRecognizerRepresentable, and refer to them by name using name. (142918018)
  • On macOS, after linking new SDKs, the style of search fields with SearchFieldPlacement.sidebar is now fixed to the toolbar. Previously the search field would scroll as the first element in the list. (143546967)
  • In apps that adopt the new design, the buttonBorderShape(_:) view modifier can be used to customize the shape of bordered buttons. Previously this modifier only affected buttons in Widgets in macOS. (145773436)
  • The buttonSizing(_:) view modifier specifies the sizing behavior of Button, Picker, Menu, and other button-producing controls. If you are using Spacer views or an infinite-width frame in your Button label to create a flexible button, apply buttonSizing(.flexible) to the Button instead. (146327046)
  • In macOS apps that adopt the new design, buttons of the .bordered style can be tinted with the tint(_:) view modifier. (150127133)

  Resolved Issues

  • Fixed: TextEditor’s undo stack might contain invalid operations for applications with multiple TextEditor views. (83650197) (FB9662463)
  • Fixed: In macOS, Button inherits its environment’s font instead of using a default font appropriate for its controlSize. Apply view modifiers to the button’s label to customize its font. (92434021)
  • Fixed: In macOS, the value label of MenuPickerStyle does not truncate when it is long enough to cause the button to be wider than its container. (93843377)
  • Fixed: The menu content of some Menu views does not update as the result of a state change. (106878937)
  • Fixed: View.onHover(perform:) and View.onContinuousHover(coordinateSpace:perform:) affect hit-testing for gestures. Gestures are not received if one of these view modifiers is used within an overlay. (108560020)
  • Fixed: Section views without isExpanded binding are collapsible in a sidebar-styled List on macOS. (115797465) (FB13192271)
  • Fixed: listSectionSpacing does not work correctly for sections that have headers and footers. For more control over the list section layout, use the listSectionMargins modifier. (140929163)
  • Fixed: On iOS, navigationSplitViewColumnWidth() does not respect the specified minimum and maximum column widths. (143529326)
  • Fixed: Multiple title views in sidebar list labels on iOS are not styled hierarchically as title and subtitle. (144253754)
  • Fixed: In custom layouts that do not implement explicit Alignment(of:in:proposal:subviews:cache:), alignment guides do not work correctly for a right-to-left layout direction. (145073832)
  • Fixed: Applying a bold modifier to Text resets the weight configuration. The interaction of bold and weight is not consistent between Text and Font. (147270079)
  • Fixed: Environment updates from outside of a popover might fail to propagate into the popover’s content view. (147954025)
  • Fixed: On platforms supporting edge-attached and non-edge-attached sheets, non-edge-attached sheets present erroneously as full-screen covers when .navigationTransition(.zoom...) is specified. If you wish to keep the full-screen cover in compact size classes, configure a sheet with: .sheet(...) { ContentView() .navigationTransition(.zoom...) } .presentationSizing(.page) .presentationCompactAdaptation(.fullScreen) (150455117)
  • Fixed: If Default Actor Isolation is set to MainActor, @Animatable macro emits concurrency warnings in Swift 5 language mode and does not compile in Swift 6 language mode. (152524435)
  • Fixed: Gestures do not have the same lower priority over the view’s existing UIGestureRecognizers and NSGestureRecognizers as they do over the view’s existing SwiftUI gestures.
    In apps built with iOS 26, macOS 26, tvOS 26, and visionOS 26, use highPriorityGesture(:isEnabled:) to make sure your gesture takes precedence over the view’s existing gestures, or use simultaneousGesture(:isEnabled:) to give your gesture the same priority as the view’s existing gestures. (155581361)

  Deprecations

  • Text concatenation using the + operator is deprecated because it makes it hard to create localized strings that are correct across all languages. Use Text interpolation instead. See documentation on Text for more info on how to produce localized strings. (128144043)

  TextKit

  New Features

  • iOS 26, tvOS 26, visionOS 26, watchOS 26, and macOS Tahoe 26 have two methods for resolving the natural alignment NSTextAlignment.natural and the last line of NSTextAlignment.justified into concrete alignments, left, and right. The first approach utilizes the UI language, which is determined by passing nil-language to NSParagraphStyle.defaultWritingDirection(forLanguage:). This behavior was employed prior to this release. The second method is new and dynamically utilizes the base writing direction for the paragraph. When the base writing direction is set to NSWritingDirection.rightToLeft, the text is aligned to right, and vice versa. The behavior is selected by API introduced in this major release: NSTextLayoutManager.resolvesNaturalAlignmentWithBaseWritingDirection, NSStringDrawingOptions.ResolvesNaturalAlignmentWithBaseWritingDirection, UITraitCollection.resolvesNaturalAlignmentWithBaseWritingDirection, and NSTextField.resolvesNaturalAlignmentWithBaseWritingDirection. (152045248)

  Resolved Issues

  • Fixed: The directionality of NSParagraphStyle indentation properties (firstLineHeadIndent, headIndent, and tailIndent) is determined by inconsistent hidden rules implemented by the TextKit typesetting engine.
    With iOS 26, macOS 26, tvOS 26, watchOS 26, and visionOS 26, the TextKit 2 typesetting engine has been standardized to utilize the resolved writing direction for the paragraph when linked with the OS 26 versions of the corresponding SDKs. For binary compatibility, applications developed with prior SDK versions will use the UI language in a subset of API interfaces. Specifically, for UILabel, NSTextField, SwiftUI.Text, and NSStringDrawing, the indentation directionality is determined by the UI language queried by passing nil to NSParagraphStyle.defaultWritingDirection() in applications built with prior SDK versions. (155893102)

  TextKit 2

  New Features

  • A new property, includesTextListMarkers, is introduced to NSTextList, NSTextContentStorage, and NSWritingToolsCoordinator. This property controls whether to include the text list marker string in the contents of NSAttributedString for paragraphs associated with NSTextList. TextKit 1 expects the marker string, while TextKit 2 does not. The TextKit 2 behavior was adopted by UIKit starting with iOS 18 (includesTextListMarkers=NO). AppKit is also adopting the TextKit 2 text list behavior starting with macOS 26. (128479184)

  Translation

  Known Issues

  • For Catalyst apps using .translationTask(), buttons in the download approval UI might not work. (151313115)
    Workaround: Either manually download the languages you need beforehand from System Settings, or build your Catalyst app with the “Optimize for Mac” setting.

  UIKit

  New Features

  • In TextKit 2, the includesTextListMarkers property has been introduced to NSTextList, NSTextContentStorage, and NSWritingToolsCoordinator. For paragraphs associated with NSTextList, the property controls whether to include the text list marker string in the NSAttributedString contents. The classes within TextKit 1 expect the marker string, while the classes within TextKit 2 do not. (144903293)

  VideoToolbox

  Resolved Issues

  • Fixed: You might experience decoding performance issues for high-bitrate HEVC, resulting in stuttering and lag. (153243806)

  Virtual Machines

  Resolved Issues

  • Fixed: Virtual machine networking fails if you start a bridge mode VM while a shared or host mode VM is running, and vice versa. The networking of the existing VM is not affected. (151477625)

  Weather

  Resolved Issues

  • Fixed: Users might see a blank white button on some tips for Weather features. The button will be operable. (152088799)

  WebKit API

  New Features

  • The load APIs on WebPage now return an AsyncSequence directly that can be used to track relevant navigation events. The currentNavigationEvent property has been removed in favor of the navigations property, which produces an indefinite sequence directly. (152414525)
  • The WebPage API now supports directly loading URLs. Additionally, when loading an HTML string, there is now a default value for the baseURL parameter. (152904248) (FB17850359)

  Resolved Issues

  • Fixed: webViewOnScrollGeometryChange might report an incorrect content size. (146576790)

  Known Issues

  • WKPreferences.isLookToScrollEnabled is not available on non-visionOS platforms. (152106377)

  Xcode

  Resolved Issues

  • Fixed: Xcode Previews usage frequently panics on macOS 26.0 Tahoe beta 4. (141641869)
