Keyboard Toolbar Padding iOS26
When I create a SwiftUI toolbar item with placement of .keyboard on iOS 26, the item appears directly on top of and in contact with the keyboard. This does not look good visually nor does it match the behavior seen in Apple's apps, such as Reminders. Adding padding to the contents of the toolbar item only expands the size of the item but does not separate the capsule background of the item from the keyboard. How can I add vertical padding or spacing to separate the toolbar item capsule from the keyboard?

Trailing closure passed to parameter of type 'Int' that does not accept a closure
I have TabView in ContentView and I want to add TabView for OnboardingView in OtherView, every things work, but it is throw error for TabView in OtherView like "Trailing closure passed to parameter of type 'Int' that does not accept a closure" I do not know why? Any idea? ContentView: struct TabView : View {       var body: some View{           VStack(spacing: 0){ ....... } OtherView:    VStack {     TabView {       ForEach(onboardingData) { onboardingItem in          OnboardingCard(onboardingItem: onboardingItem)       }   }   .tabViewStyle(PageTabViewStyle(indexDisplayMode: .automatic))   .indexViewStyle(PageIndexViewStyle (backgroundDisplayMode:   .always))   .foregroundColor(.white) }

NSTextView.shouldDrawInsertionPoint doesn't work with TextKit 2
The following code only ever causes shouldDrawInsertionPoint to be printed (no drawInsertionPoint), but even if that method returns false, the blinking insertion point is still drawn. On the other hand, with TextKit 1 it works as expected. Is there a way to hide the default insertion point in TextKit 2? My app draws its own. I've filed FB13684251. class TextView: NSTextView { override var shouldDrawInsertionPoint: Bool { print("shouldDrawInsertionPoint") return false } override func drawInsertionPoint(in rect: NSRect, color: NSColor, turnedOn flag: Bool) { print("drawInsertionPoint", flag) } } ``

UIDocumentPickerViewController provides corrupt copy of file when user taps multiple times on file
We're trying to implement a backup/restore data feature in our business productivity iPad app using UIDocumentPickerViewController and AppleArchive, but discovered odd behavior of [UIDocumentPickerViewController initForOpeningContentTypes: asCopy:YES] when reading large archive files from a USB drive. We've duplicated this behavior with iPadOS 16.6.1 and 17.7 when building our app with Xcode 15.4 targeting minimum deployment of iPadOS 16. We haven't tested this with bleeding edge iPadOS 18. Here's our Objective-C code which presents the picker: NSArray* contentTypeArray = @[UTTypeAppleArchive]; UIDocumentPickerViewController* docPickerVC = [[UIDocumentPickerViewController alloc] initForOpeningContentTypes:contentTypeArray asCopy:YES]; docPickerVC.delegate = self; docPickerVC.allowsMultipleSelection = NO; docPickerVC.shouldShowFileExtensions = YES; docPickerVC.modalPresentationStyle = UIModalPresentationPopover; docPickerVC.popoverPresentationController.sourceView = self.view; [self presentViewController:docPickerVC animated:YES completion:nil]; The UIDocumentPickerViewController remains visible until the selected external archive file has been copied from the USB drive to the app's local tmp sandbox. This may take several seconds due to the slow access speed of the USB drive. During this time the UIDocumentPickerViewController does NOT disable its tableview rows displaying files found on the USB drive. Even the most patient user will tap the desired filename a second (or third or fourth) time since the user's initial tap appears to have been ignored by UIDocumentPickerViewController, which lacks sufficient UI feedback showing it's busy copying the selected file. When the user taps the file a second time, UIDocumentPickerViewController apparently begins to copy the archive file once again. The end result is a truncated copy of the selected file based on the time between taps. For instance, a 788 MB source archive may be copied as a 56 MB file. Here, the UIDocumentPickerDelegate receives a 56 MB file instead of the original 788 MB of data. Not surprisingly, AppleArchive fails to decrypt the local copy of the archive because it's missing data. Instead of failing gracefully, AppleArchive crashes in AAArchiveStreamClose() (see forums post 765102 for details). Does anyone know if there's a workaround for this strange behavior of UIDocumentPickerViewController?

iOS 14 UIPickerView Selected View Background Color
I have noticed that in iOS 14 the UIPickerView has by default a light grey background on the selected Row like shown here. https://developer.apple.com/design/human-interface-guidelines/ios/controls/pickers/ I noticed also that pickerView.showsSelectionIndicator is deprecated on iOS 14. Is there a way to change the background color to white and add separators to achieve a pre iOS 14 UIPickerView style? Thank you

Exception unarchiving UIToolbar in iOS 18.5 simulator with Xcode 26 beta 2
I'm running into a persistent problem with the iOS 18.5 simulator in Xcode 26 beta 2. I have built a very simple test app with a storyboard that includes only a toolbar added to the ViewController scene in the storyboard. The test app runs fine in iOS 26 simulators.When I try to run it in the iOS 18.5 simulator for iPhone Pro or iPad (16), it fails while unarchiving the storyboard (as far as I can tell) with this error message in the Xcode console: *** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView because no class named TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)' terminating due to uncaught exception of type NSException CoreSimulator 1043 - Device: iPad (A16) (3E70E25F-8434-4541-960D-1B58EB4037F3) - Runtime: iOS 18.5 (22F77) - DeviceType: iPad (A16) I'd love a simple workaround for this.

dropDestination does not work inside List
I've discovered an issue with using iOS 16's Transferable drag-and-drop APIs for SwiftUI. The dropDestination modifier does not work when applied to a subview of a List. This code below will not work, unless you replace the List with a VStack or any other container (which, of course, removes all list-specific rendering). The draggable modifier will still work and the item will drag, but the dropDestination view won't react to it and neither closure will be called. struct MyView: View { var body: some View { List { Section { Text("drag this title") .font(.largeTitle) .draggable("a title") } Section { Color.pink .frame(width: 400, height: 400) .dropDestination(for: String.self) { receivedTitles, location in true } isTargeted: { print($0) } } } } } Has anyone encountered this bug and perhaps found a workaround?

Swipe to go back still broken with Zoom navigation transition.
When you use .navigationTransition(.zoom(sourceID: "placeholder", in: placehoder)) for navigation animation, going back using the swipe gesture is still very buggy on IOS26. I know it has been mentioned in other places like here: https://developer.apple.com/forums/thread/796805?answerId=856846022#856846022 but nothing seems to have been done to fix this issue. Here is a video showing the bug comparing when the back button is used vs swipe to go back: https://imgur.com/a/JgEusRH I wish there was a way to at least disable the swipe back gesture until this bug is fixed.

iOS 26 Beta breaks scroll/gesture in SwiftUI chat (worked in iOS 18): Simultaneous gestures & ScrollViewReader issues
Hi all, After upgrading to the iOS 26 beta, the scrolling in my SwiftUI chat view is completely broken. The exact same code works perfectly on iOS 18. Context: I have a chat view using ScrollViewReader and a vertically-reversed ScrollView (with .rotationEffect(.degrees(180))). Each message row (MessageBubble) uses multiple simultaneousGesture handlers: Horizontal drag for swipe-to-reply (and other actions: pin, delete) Long press for showing popover/actions Vertical scroll for normal chat scrolling This was working great on iOS 18. In iOS 26 beta, the vertical scroll is either completely disabled, jittery, or hijacked by the message row’s drag gestures, even though .simultaneousGesture is used (see code below). Minimal Repro Sample MessageListView.swift swift Copy Edit ScrollViewReader { proxy in ScrollView(.vertical, showsIndicators: false) { LazyVStack(spacing: 0) { // ... grouped messages ForEach(...) { ... MessageBubble(...) // see below } Color.clear.frame(height: 8).id("BOTTOM_ANCHOR") } .padding(.horizontal, 4) .rotationEffect(.degrees(180)) } .rotationEffect(.degrees(180)) } MessageBubble.swift struct MessageBubble: View { // ... var body: some View { // horizontal swipe-to-reply gesture let dragGesture = DragGesture(minimumDistance: 10) // ... ZStack { // ... HStack { ... } // ... .simultaneousGesture( DragGesture(minimumDistance: 0) // for long press // ... ) .simultaneousGesture(dragGesture) // for horizontal swipe } // ... } }

NSScrollView scrolling hitch
When scrolling a basic NSScrollView there seems to be a sudden jump after each flick. Scrolling does not appear smooth and is disorientating. A scroll jump seems to happen directly after letting go of a scroll flick using a trackpad/mouse. Right at that moment the scroll turns into a momentum scroll, slowly decreasing the speed. But the first frame after the gesture the content jumps forward, more than what is expected. Observations: Counterintuitively, scrolling appears to be smoother when disabling NSScrollView.isCompatibleWithResponsiveScrolling. If disabled using a custom NSScrollView subclass there is no large jump anymore. Scrolling also appears to be smoother using a SwiftUI ScrollView. I assume that has the same behaviour as a disabled isCompatibleWithResponsiveScrolling Ironically a WKWebView scrolls much smoother. No sudden jump is observable. It also seems to scroll with faster acceleration, but the individual frames do appear smoother. Why is this better than a native NSScrollView? Elastic scrolling at the bounds of the scroll view also appears much smoother for WKWebViews. When pulling to refresh there is a jump for NSScrollView/SwiftUI, but not for WKWebView. When using an NSScrollView with isCompatibleWithResponsiveScrolling disabled, scrolling appears just as smooth as WKWebView on macOS 13 Ventura and below. On macOS 14 Sonoma scrolling behaviour is suddenly different. Please see a sample project with 4 different scroll views side by side: https://github.com/floorish/ScrollTest Screen recordings show the sudden jumps when scrolling and when elastic scrolling. Tested on Intel & Arm Macs, macOS 11 Big Sur through 15 Sequoia, built with Xcode 16. Should isCompatibleWithResponsiveScrolling be disabled on Sonoma+? Are there any drawbacks? There is also no overdraw anymore since Monterey, as described in https://developer.apple.com/library/archive/releasenotes/AppKit/RN-AppKitOlderNotes/#10_9Scrolling Even with responsive scrolling disabled, why is WKWebView scrolling much smoother than NSScrollView?

Accessibility Permission In Sandbox For Keyboard
Hello! My question is about 1) if we can use any and or all accessibility features within a sandboxed app and 2) what steps we need to take to do so. Using accessibility permissions, my app was working fine in Xcode. It used NSEvent.addGlobalMonitorForEvents and localMoniter, along with CGEvent.tapCreate. However, after downloading the same app from the App Store, the code was not working. I believe this was due to differences in how permissions for accessibility are managed in Xcode compared to production. Is it possible for my app to get access to all accessibility features, while being distributed on the App Store though? Do I need to add / request any special entitlements like com.apple.security.accessibility? Thanks so much for the help. I have done a lot of research on this online but found some conflicting information, so wanted to post here for a clear answer.

'tabViewBottomAccessory' leaves an empty accessory area when conditionally hidden
We use SwiftUI's .tabViewBottomAccessory in our iOS apps for displaying an Audio MiniPlayer View (like in the Apple Music App). TabView(selection: $viewModel.selectedTab) { // Tabs here } .tabViewBottomAccessory { if viewModel.showAudioMiniPlayer { MiniPlayerView() } } The Problem This code works perfectly on iOS 26.0. When viewModel.showAudioMiniPlayer is false, the accessory is completely hidden. However, on iOS 26.1 (23B5059e), when 'viewModel.showAudioMiniPlayer' becomes false, the MiniPlayerView disappears, but an empty container remains, leaving a blank space above the tab bar. Is this a known Bug in iOS 26.1 and are there any effective workarounds?

A basic DocumentGroup App presents two back "<" buttons on the navigation bar.
Please has anyone found a workaround for duplicate back buttons appearing on the toolbar of a ContentView launched from a DocumentGroup? The problem occurs with Xcode 14.0 running a basic DocumentGroup App on iOS 16.0. To reproduce, simply build a new project using the "Document App" template. Build and run in the iOS/iPadOS simulator or on an iOS/iPadOS device. Two back buttons appear. Only one functions. I've not found a way to eliminate the dud. This problem has occurred throughout the Xcode 14.0 beta program.

.glassEffect(_in:) crushing on iOS 26 public beta.
In one of my apps, i am using .glassEffect(_:In) to add glass effect on various elements. The app always crushes when a UI element with glassEffect(_in:) modifier is being rendered. This only happens on device running iOS 26 public beta. I know this for certain because I connected the particular device to xcode and run the app on the device. When i comment out the glassEffect modifier, app doesn't crush. Is it possible to check particular realeases with #available? If not, how should something like this be handled. Also how do i handle such os level erros without the app crushing. Thanks.

Widget link broken by `.desaturated` image rendering mode
Using desaturated mode on an image in a widget will break any links or buttons that use the image as their 'label'. Using the following will just open the app as if there was no link at all - therefore just using the fallback userActivity handler, or any .widgetURL() urls provided. Link(destination: URL(string: "bug://never-works")!) { Image("puppy") .widgetAccentedRenderingMode(.desaturated) } The same goes for buttons: Button(intent: MyDemoIntent()) { Image("puppy") .widgetAccentedRenderingMode(.desaturated) } I've tried hacky solutions like putting the link behind the image using a ZStack, and disabling hit testing on the image, but they don't work. Anything else to try? Logged as Feedback #15152620.

SwiftUI TextField with optional value working for @State but not @Binding properties
I've encountered a potential bug where a TextField connected to an optional value (not a string) works as expected when bound to a @State property, but won't update a @Binding property. Here is some example code import SwiftUI struct ContentView: View { @Binding var boundValue: Double? @State private var stateValue: Double? = 55 var body: some View { TextField("Bound value", value: $boundValue, format: .number) Text("\(boundValue ?? .nan)") TextField("State value", value: $stateValue, format: .number) Text("\(stateValue ?? .nan)") } } #Preview { ContentView(boundValue: .constant(42.00)) } It's as though the optional value stored externally is preventing the value updating. Can anyone confirm whether this is intentional, or a bug? This is in Xcode 26b6, on macOS Tahoe 26b8, but from this query it looks like the problem has existed for years.

Duplicate toolbar item and wrong document name in SwiftUI document based app
My app is a SwiftUI document based app using DocumentGroupLaunchScene. In iOS(iPadOS) 18.4, when it launches, it has duplicate toolbar items, and when I close the current document and open other documents, it adds more duplicates. It also shows a wrong document name, which shows the first opened document name. This issue can be reproduced in the sample code (Building a document-based app with SwiftUI). I have submitted Feedback (FB17025216), but not sure if this is a known bug or if I'm missing anything.

tvOS 18.0 Siri back button behavior bug
On testing my app with tvOS 18, I have noticed the Siri Remote back button no longer provides system-provided behavior when interacting with tab bar controller pages. Instead of moving focus back to the tab bar when pressed, the back button will close the app, as if the Home button was pressed. This occurs both on device and in the Simulator. Create tvOS project with a tab bar controller. Create pages/tabs which contain focusable items (ie. buttons) Scroll down to any focusable item (ie. a button or UICollectionView cell) Hit the Siri Remote back button. See expect behavior below: Expected behavior: System-provided behavior should move focus back to the tab bar at the top of the screen. Actual results: App is closed and user is taken back to the Home Screen. Has anyone else noticed this behavior?

Keyboard Toolbar Padding iOS26

This does not look good visually nor does it match the behavior seen in Apple's apps, such as Reminders. Adding padding to the contents of the toolbar item only expands the size of the item but does not separate the capsule background of the item from the keyboard. How can I add vertical padding or spacing to separate the toolbar item capsule from the keyboard?

If disabled using a custom NSScrollView subclass there is no large jump anymore. Scrolling also appears to be smoother using a SwiftUI ScrollView. I assume that has the same behaviour as a disabled isCompatibleWithResponsiveScrolling Ironically a WKWebView scrolls much smoother. No sudden jump is observable. It also seems to scroll with faster acceleration, but the individual frames do appear smoother. Why is this better than a native NSScrollView? Elastic scrolling at the bounds of the scroll view also appears much smoother for WKWebViews. When pulling to refresh there is a jump for NSScrollView/SwiftUI, but not for WKWebView. When using an NSScrollView with isCompatibleWithResponsiveScrolling disabled, scrolling appears just as smooth as WKWebView on macOS 13 Ventura and below. On macOS 14 Sonoma scrolling behaviour is suddenly different. Please see a sample project with 4 different scroll views side by side: https://github.com/floorish/ScrollTest Screen recordings show the sudden jumps when scrolling and when elastic scrolling. Tested on Intel & Arm Macs, macOS 11 Big Sur through 15 Sequoia, built with Xcode 16. Should isCompatibleWithResponsiveScrolling be disabled on Sonoma+? Are there any drawbacks? There is also no overdraw anymore since Monterey, as described in https://developer.apple.com/library/archive/releasenotes/AppKit/RN-AppKitOlderNotes/#10_9Scrolling Even with responsive scrolling disabled, why is WKWebView scrolling much smoother than NSScrollView?

Accessibility Permission In Sandbox For Keyboard
Hello! My question is about 1) if we can use any and or all accessibility features within a sandboxed app and 2) what steps we need to take to do so. Using accessibility permissions, my app was working fine in Xcode. It used NSEvent.addGlobalMonitorForEvents and localMoniter, along with CGEvent.tapCreate. However, after downloading the same app from the App Store, the code was not working. I believe this was due to differences in how permissions for accessibility are managed in Xcode compared to production. Is it possible for my app to get access to all accessibility features, while being distributed on the App Store though? Do I need to add / request any special entitlements like com.apple.security.accessibility? Thanks so much for the help. I have done a lot of research on this online but found some conflicting information, so wanted to post here for a clear answer.

'tabViewBottomAccessory' leaves an empty accessory area when conditionally hidden
We use SwiftUI's .tabViewBottomAccessory in our iOS apps for displaying an Audio MiniPlayer View (like in the Apple Music App). TabView(selection: $viewModel.selectedTab) { // Tabs here } .tabViewBottomAccessory { if viewModel.showAudioMiniPlayer { MiniPlayerView() } } The Problem This code works perfectly on iOS 26.0. When viewModel.showAudioMiniPlayer is false, the accessory is completely hidden. However, on iOS 26.1 (23B5059e), when 'viewModel.showAudioMiniPlayer' becomes false, the MiniPlayerView disappears, but an empty container remains, leaving a blank space above the tab bar. Is this a known Bug in iOS 26.1 and are there any effective workarounds?

A basic DocumentGroup App presents two back "<" buttons on the navigation bar.
Please has anyone found a workaround for duplicate back buttons appearing on the toolbar of a ContentView launched from a DocumentGroup? The problem occurs with Xcode 14.0 running a basic DocumentGroup App on iOS 16.0. To reproduce, simply build a new project using the "Document App" template. Build and run in the iOS/iPadOS simulator or on an iOS/iPadOS device. Two back buttons appear. Only one functions. I've not found a way to eliminate the dud. This problem has occurred throughout the Xcode 14.0 beta program.

.glassEffect(_in:) crushing on iOS 26 public beta.
In one of my apps, i am using .glassEffect(_:In) to add glass effect on various elements. The app always crushes when a UI element with glassEffect(_in:) modifier is being rendered. This only happens on device running iOS 26 public beta. I know this for certain because I connected the particular device to xcode and run the app on the device. When i comment out the glassEffect modifier, app doesn't crush. Is it possible to check particular realeases with #available? If not, how should something like this be handled. Also how do i handle such os level erros without the app crushing. Thanks.

Widget link broken by `.desaturated` image rendering mode
Using desaturated mode on an image in a widget will break any links or buttons that use the image as their 'label'. Using the following will just open the app as if there was no link at all - therefore just using the fallback userActivity handler, or any .widgetURL() urls provided. Link(destination: URL(string: "bug://never-works")!) { Image("puppy") .widgetAccentedRenderingMode(.desaturated) } The same goes for buttons: Button(intent: MyDemoIntent()) { Image("puppy") .widgetAccentedRenderingMode(.desaturated) } I've tried hacky solutions like putting the link behind the image using a ZStack, and disabling hit testing on the image, but they don't work. Anything else to try? Logged as Feedback #15152620.

SwiftUI TextField with optional value working for @State but not @Binding properties
I've encountered a potential bug where a TextField connected to an optional value (not a string) works as expected when bound to a @State property, but won't update a @Binding property. Here is some example code import SwiftUI struct ContentView: View { @Binding var boundValue: Double? @State private var stateValue: Double? = 55 var body: some View { TextField("Bound value", value: $boundValue, format: .number) Text("\(boundValue ?? .nan)") TextField("State value", value: $stateValue, format: .number) Text("\(stateValue ?? .nan)") } } #Preview { ContentView(boundValue: .constant(42.00)) } It's as though the optional value stored externally is preventing the value updating. Can anyone confirm whether this is intentional, or a bug? This is in Xcode 26b6, on macOS Tahoe 26b8, but from this query it looks like the problem has existed for years.

Duplicate toolbar item and wrong document name in SwiftUI document based app
My app is a SwiftUI document based app using DocumentGroupLaunchScene. In iOS(iPadOS) 18.4, when it launches, it has duplicate toolbar items, and when I close the current document and open other documents, it adds more duplicates. It also shows a wrong document name, which shows the first opened document name. This issue can be reproduced in the sample code (Building a document-based app with SwiftUI). I have submitted Feedback (FB17025216), but not sure if this is a known bug or if I'm missing anything.

tvOS 18.0 Siri back button behavior bug
On testing my app with tvOS 18, I have noticed the Siri Remote back button no longer provides system-provided behavior when interacting with tab bar controller pages. Instead of moving focus back to the tab bar when pressed, the back button will close the app, as if the Home button was pressed. This occurs both on device and in the Simulator. Create tvOS project with a tab bar controller. Create pages/tabs which contain focusable items (ie. buttons) Scroll down to any focusable item (ie. a button or UICollectionView cell) Hit the Siri Remote back button. See expect behavior below: Expected behavior: System-provided behavior should move focus back to the tab bar at the top of the screen. Actual results: App is closed and user is taken back to the Home Screen. Has anyone else noticed this behavior?
