Hello, I have been trying for some time to change the color of native UITabBar in UITabBarController through UITabBarAppearance, but nothing works and the text is still black in the Xcode Beta 3 on iPadOS 26 while it works correctly in the previous OS versions. Here is the code: let color = UIColor.white let stackedAppearance = UITabBarItemAppearance() stackedAppearance.normal.iconColor = color stackedAppearance.normal.titleTextAttributes = [ .foregroundColor: color ] stackedAppearance.selected.iconColor = color stackedAppearance.selected.titleTextAttributes = [ .foregroundColor: color ] let inlineAppearance = UITabBarItemAppearance() inlineAppearance.normal.iconColor = color inlineAppearance.normal.titleTextAttributes = [ .foregroundColor: color ] inlineAppearance.selected.iconColor = color inlineAppearance.selected.titleTextAttributes = [ .foregroundColor: color ] let tabAppearance = UITabBarAppearance() tabAppearance.compactInlineLayoutAppearance = inlineAppearance tabAppearance.inlineLayoutAppearance = inlineAppearance tabAppearance.stackedLayoutAppearance = stackedAppearance UITabBar.appearance().standardAppearance = tabAppearance UITabBar.appearance().scrollEdgeAppearance = tabAppearance

Starting with iOS 26 beta, I'm encountering an intermittent crash in production builds related to Auto Layout and background threading. This crash did not occur on iOS 18 or earlier and has become reproducible only on devices running iOS 26 betas. We have already performed a thorough audit of our code: • Verified that all UIKit view hierarchy and layout mutations occur on the main thread. • Re-tested with strict logging—confirmed all remaining layout/constraint/view updates are performed on the main thread. • No third-party UI SDKs are used in the relevant flow. Despite that, the crash still occurs and always from a background thread, during internal UIKit layout commits. Fatal Exception: NSInternalInconsistencyException Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread. 0 MyApp 0x7adbc8 FIRCLSProcessRecordAllThreads + 172 1 MyApp 0x7adfd4 FIRCLSProcessRecordAllThreads + 1208 2 MyApp 0x7bc4b4 FIRCLSHandler + 56 3 MyApp 0x7bc25c __FIRCLSExceptionRecord_block_invoke + 100 4 libdispatch.dylib 0x1b7cc _dispatch_client_callout + 16 5 libdispatch.dylib 0x118a0 _dispatch_lane_barrier_sync_invoke_and_complete + 56 6 MyApp 0x7bb1f0 FIRCLSExceptionRecord + 224 7 MyApp 0x7bbd1c FIRCLSExceptionRecordNSException + 456 8 MyApp 0x7badf4 FIRCLSTerminateHandler() + 396 9 Intercom 0x86684 IntercomSDK_sentrycrashcm_cppexception_getAPI + 308 10 libc++abi.dylib 0x11bdc std::__terminate(void (*)()) + 16 11 libc++abi.dylib 0x15314 __cxa_get_exception_ptr + 86 12 libc++abi.dylib 0x152bc __cxxabiv1::failed_throw(__cxxabiv1::__cxa_exception*) + 90 13 libobjc.A.dylib 0x3190c objc_exception_throw + 448 14 CoreAutoLayout 0x13a4 -[NSISEngine optimize] + 314 15 CoreAutoLayout 0x1734 -[NSISEngine _optimizeWithoutRebuilding] + 72 16 CoreAutoLayout 0x1404 -[NSISEngine optimize] + 96 17 CoreAutoLayout 0xee8 -[NSISEngine performPendingChangeNotifications] + 104 18 UIKitCore 0x27ac8 -[UIView(Hierarchy) layoutSubviews] + 136 19 UIKitCore 0xfe760 -[UIWindow layoutSubviews] + 68 20 UIKitCore 0x234228 -[UITextEffectsWindow layoutSubviews] + 44 21 UIKitCore 0x27674 -[UIImageView animationImages] + 912 22 UIKitCore 0x28134 -[UIView(Internal) _viewControllerToNotifyOnLayoutSubviews] + 40 23 UIKitCore 0x18c2898 -[UIView(CALayerDelegate) layoutSublayersOfLayer:] + 2532 24 QuartzCore 0xabd98 CA::Layer::perform_update_(CA::Layer*, CALayer*, unsigned int, CA::Transaction*) + 116 25 QuartzCore 0x8e810 CA::Layer::update_if_needed(CA::Transaction*, unsigned int, unsigned int) + 600 26 QuartzCore 0xad45c CA::Layer::layout_and_display_if_needed(CA::Transaction*) + 200 27 QuartzCore 0x6e30c CA::Context::commit_transaction(CA::Transaction*, double, double*) + 540 28 QuartzCore 0x9afc4 CA::Transaction::commit() + 644 29 QuartzCore 0x16974c CA::Transaction::release_thread(void*) + 180 30 libsystem_pthread.dylib 0x4c28 _pthread_tsd_cleanup + 620 31 libsystem_pthread.dylib 0x4998 _pthread_exit + 84 32 libsystem_pthread.dylib 0x5e3c pthread_atfork + 54 33 libsystem_pthread.dylib 0x1440 _pthread_wqthread + 428 34 libsystem_pthread.dylib 0x8c0 start_wqthread + 8 Any ideas?

Hi, I am running iOS Simulator on iOS 26 and I am trying to change unselectedItemTintColor of UITabBarItem in my TabBarViewController but it did not work when I tried following ways: Setting an iconColor through UITabBarAppearance() class Setting unselected item tint color like tabBar.unselectedItemTintColor = .black As an example attached file, I would like to set Settings tab's item color (icon + title) with different one when it is unselected.

I am using the TabView control in SwiftUI on a tvOS 18 target with the style of sidebarAdaptable. When I have 7 or less tabs things operate correctly. When I add an 8th tab and you navigate to the contents of the tab the menu collapses as expected but you cannot navigate back to restore the menu. This code reproduces the issue: import SwiftUI struct ContentView: View { var body: some View { TabView { Tab("Tab1", systemImage: "person.circle") { Button("Button1") {} } Tab("Tab2", systemImage: "person.circle") { Button("Button2") {} } Tab("Tab3", systemImage: "person.circle") { Button("Button3") {} } Tab("Tab4", systemImage: "person.circle") { Button("Button4") {} } Tab("Tab5", systemImage: "person.circle") { Button("Button5") {} } Tab("Tab6", systemImage: "person.circle") { Button("Button6") {} } Tab("Tab7", systemImage: "person.circle") { Button("Button7") {} } Tab("Tab8", systemImage: "person.circle") { Button("Button8") {} } } .tabViewStyle(.sidebarAdaptable) } } If you eliminate Tab 8 the problem goes away. You can navigate back to the menu by moving to the left. Notably the Destination Video sample also reproduces this issue: https://developer.apple.com/documentation/visionos/destination-video To reproduce: Load the above code or Destination Video sample. Navigate right (click right on remote or swipe right). Menu dismisses and just shows the item you have selected in the upper left corner. Try to navigate left by clicking left on the remote or swiping left. It looks like the collapsed menu gets focus briefly, screen elements flash but the focus remains outside the menu. Has anyone else encountered this issue?

I have a custom document-based iOS app that also runs on macOS. After implementing -activityItemsConfiguration to enable sharing from the context menu, I found that the app crashes on macOS when selecting Share… from the context menu and then selecting Save (i.e. Save to Files under iOS). This problem does not occur on iOS, which behaves correctly. - (id<UIActivityItemsConfigurationReading>)activityItemsConfiguration { NSItemProvider * provider = [[NSItemProvider alloc] initWithContentsOfURL:self.document.presentedItemURL]; UIActivityItemsConfiguration * configuration = [UIActivityItemsConfiguration activityItemsConfigurationWithItemProviders:@[ provider ]]; // XXX crashes with com.apple.share.System.SaveToFiles return configuration; } Additionally, I found that to even reach this crash, the workaround implemented in the NSItemProvider (FBxxx) category of the sample project is needed. Without this, the app will crash much earlier, due to SHKItemIsPDF() erroneously invoking -pathExtension on an NSItemProvider. This appears to be a second bug in Apple’s private ShareKit framework. #import <UniformTypeIdentifiers/UniformTypeIdentifiers.h> @implementation NSItemProvider (FBxxx) // XXX SHKItemIsPDF() invokes -pathExtension on an NSItemProvider (when running under macOS, anyway) -> crash - (NSString *)pathExtension { return self.registeredContentTypes.firstObject.preferredFilenameExtension; } @end Again, this all works fine on iOS (17.5) but crashes when the exact same app build is running on macOS (14.5). I believe these bugs are Apple's. Any idea how to avoid the crash? Is there a way to disable the "Save to Files" option in the sharing popup? I filed FB13819800 with a sample project that demonstrates the crash on macOS. I was going to file a TSI to get this resolved, but I see that DTS is not responding to tech support incidents until after WWDC.

Hi! We've recently done a big migration to Swift 6 language mode in our app and are now getting reports of crashes occurring due to closures in our SwiftUI code (most often the view builder in ForEach) not running on the main queue but instead running on the queue com.apple.SwiftUI.AsyncRenderer. One example of a call stack (ScheduleListView is our view that is in Swift 6 mode): Thread 16 #0 (null) in _dispatch_assert_queue_fail () #1 (null) in dispatch_assert_queue$V2.cold.1 () #2 (null) in dispatch_assert_queue () #3 (null) in swift_task_isCurrentExecutorWithFlagsImpl(swift::SerialExecutorRef, swift::swift_task_is_current_executor_flag) () #4 (null) in closure #2 in closure #1 in closure #1 in ScheduleListView.body.getter () #5 (null) in closure #1 in ForEachState.item(at:offset:) () #6 (null) in partial apply for closure #1 in ForEachState.item(at:offset:) () #8 (null) in partial apply for closure #1 in _withObservation<A>(do:) () .... (We have many other crashes with similar crash reports but in other views) Has anybody else run into something similar? Is there anything (other than simply reverting to Swift 5 mode again) that we can do to fix or at least reduce the amount of crashes? We're having a hard time finding anything out of the ordinary that we're doing in our views. Regards

After updating to Xcode 26 my XCUITests are now failing as during execution exceptions are being raised and caught by my catch all breakpoint These exceptions are only raised during testing, and seem to be referencing some private internal property. It happens when trying to tap a button based off an accessibilityIdentifier e.g. accessibilityIdentifier = "tertiary-button" ... ... app.buttons["tertiary-button"].tap() The full error is: Thread 1: "[<UIKit.ButtonBarButtonVisualProvider 0x600003b4aa00> valueForUndefinedKey:]: this class is not key value coding-compliant for the key _titleButton." Anyone found any workarounds or solutions? I need to get my tests running on the liquid glass UI

I am using AlarmKit to schedule alarms in an app I am working on, however my scheduled alarms only show up on the lock screen. If I am on the home screen or elsewhere I only hear the sound of the alarm, but no UI shows up. Environment: iOS 26 beta 3 Xcode 26 beta 3

Hi there, Upon using List View for tabular information showcase on both iOS and iPadOS, I have come to realize that the drag and drop support works only for iPadOS but not iOS. Although it is possible to workaround this by using a ScrollView wrapping around a LazyVStack instead, the editing mode along with left-wipe to delete feature would be missing. Not to mention that this workaround only supports single item rather than multiple items. Therefore, I am here to ask if the drag and drop will come to support devices running iOS, and if so, when will this feature ship. If not, will LazyVStack/LazyHStack support native editing mode. Thank you for your time.

How do we disable the new swipe left anywhere to navigate back? I already use that swipe motion for custom actions in my app.

I have a macOS app made with SwiftUI where I want to show a list of data in a tabular fashion. SwiftUI Table seems to be the only built-in component that can do this. I would like to let the user size the columns and have their widths restored when the app is relaunched. I can find no documentation on how to do this and it does not seem to be saved and restored automatically. I can find no way to listen for changes in the column widths when the user resizes and no way to set the size from code. For a macOS app it seems that the only way to set the width of a column is to use e.g. .width(min: 200, max: 200). This in effect disables resizing of the column. It seems that idealSize is totally ignored on macOS. Any suggestions?

In iOS 26.1, SwiftUI's tabViewBottomAccessory API cannot control visibility properly. The tabViewBottomAccessory remains always visible, which is inconsistent with the behavior in iOS 26.0 / iOS 26.0.1. ` struct ContentView: View { enum Tabs { case first } @State private var selection: Tabs = .first @State private var showBottomAccessory: Bool = true var body: some View { tabView } var tabView: some View { TabView(selection: $selection) { Tab(value: .first) { content } label: { VStack { Text("first") } } } .tabViewBottomAccessory { if showBottomAccessory { Text("BottomAccessory") } } } var content: some View { Button("change") { showBottomAccessory.toggle() } } } `

When using my app's complications with either Siri Intents or App Intents after syncing .watchface files, the complications appear without names in the iOS Watch app's complication picker. This leads to complications showing as blank entries without previews in the native watch app selector. I'm using WidgetKit to create Watch complications with both approaches: AppIntents and Siri Intents. We've tried multiple approaches with our WidgetKit watch complications: Switching between IntentConfiguration and StaticConfiguration Using different naming conventions for kind strings Ensuring display names are properly set Testing across different watchOS versions But the result is always the same: after syncing .watchface files, our complications appear unnamed in the Watch app's complication picker. Is this a known limitation with .watchface syncing, a bug in the current implementation, or is there a specific requirement we're missing to maintain complication names during the sync process?

It happens on a brand new SwiftUI Xcode project with nothing in it but the default base code. When I build and run, I get "Error creating the CFMessagePort needed to communicate with PPT." After some Googling, I know it has something to do with Performance Tools. I don't know what's causing it. I'm running 16.2 on a brand new M4 Mac mini.

I recently started exploring the latest version of SwiftUI and came across a issue while working with TabView and NavigationStack. I downloaded Apple’s provided example code and began making changes to explore new SwiftUI changes. i added navigationtitle and toolbarBackground to first two tab. However, I noticed that the navigation bar "jumps" or resets when switching between tabs, even in their own example implementation. Here’s a simplified version of the example code I was testing: file name - WatchNowView .navigationTitle("Watch Now") .navigationBarTitleDisplayMode(.inline) .toolbarBackground(Color("AccentColor"),for: .navigationBar) file name - LibraryView .navigationTitle("Library") .navigationBarTitleDisplayMode(.inline) .toolbarBackground(Color("AccentColor"),for: .navigationBar) Here is a sample code link (provided by Apple developer document) : destination-video I have attached a gif below demonstrating this issue: Questions: Is this behavior expected in the latest version of SwiftUI, or is it a bug in the framework's handling of TabView and NavigationStack? Is this behavior expected as all tabbar item have their own nativationStack? Are there any official recommendations for maintaining seamless navigation experiences when using navigationStack and TabView? This behavior detracts from the otherwise smooth experience SwiftUI aims to provide. If anyone has encountered this issue and found a workaround, I’d greatly appreciate your insights. I hope Apple can review this problem to enhance the usability of SwiftUI. Thank you!

We are using a TabView as the TabBarController in our app for main navigation. On one of the tabs we have a view that consists of a TabView with .tabViewStyle(.page) in order to scroll horizontally between pages inside of that specific tab. The .tabBarMinimizeBehavior(.onScrollDown) works on all the other TabItem views, but for this one it does not recognise any vertical scrolling in any of the pages, in order to minimize the TabBar. I believe this is a bug? If we don't wrap the views inside the TabView with .page style, we are able to get the expected behaviour using the tabBarMinimizeBehavior. Please let us know if this is going to be fixed in a future iOS 26 beta release.

We are building a CarPlay app and have run into an issue with data updates. When the app is running on the CarPlay display and the iPhone screen is locked, no data updates are shown on the CarPlay screen. As soon as the phone is unlocked, the data updates appear instantly on the CarPlay display. Has anyone encountered this behavior before? Is there a specific setting, entitlement, or background mode we need to enable in order to ensure the CarPlay app continues to receive and display data while the iPhone is locked? Any guidance would be greatly appreciated.

Hello. Is there a good SwiftUI approach on getting the TextEditor cursor position? I have a TextEditor and sometimes when we have a longer text inside it, the cursor is not seen because the keyboard is above covering the bottom of the TextEditor. I would like to somehow detect the position of the cursor, and if it's on the last line of the TextEditor, scroll to the bottom. I've already checked a bit and didn't find any good method of doing this in SwiftUI. If you have any ideas on how to do this, or even a different method any help would be highly appreciated. Thank you!
