.contactAccessPicker shows blank sheet on iOS 26.1
I’m running into an issue using .contactAccessPicker on a device running iOS 26.1 - a blank sheet appears instead of the expected Contact Access Picker. It works on: Simulator (iOS 26.0) Device + Simulator (iOS 18.6) The issue appears specific to real devices on iOS 26.0+. Environment: Device: iPhone 16 Pro iOS Versions Tested: 26.0 and 26.1 Xcode 26.0.1 SwiftUI app, deployment target: iOS 17+ @available(iOS 18.0, *) private var contactPicker: some View { contactsSettingsButton("Title") { showContactPicker = true } .contactAccessPicker(isPresented: $showContactPicker) { _ in Task { await contactManager.fetchContacts() showSelectContacts = true } } } Filed a Feedback: FB20929400 Is there a known workaround?

touchesEnded: not triggered on newer iOS when view is inside UIScrollView (was working on iOS 18)
Hi everyone, I’m facing an issue with touch handling on newer iOS versions. I have a custom view controller implemented in Objective-C that overrides touchesEnded:. The same code works correctly on iOS 18, but on newer iOS versions (tested on iOS 26), touchesEnded: is no longer being triggered. Important observations: touchesBegan: is triggered. touchesEnded: is NOT triggered. touchesCancelled: is also NOT triggered. No code changes were made between iOS 18 and iOS 26. Same code, same sample works fine in iOS18 device but not in iOS26 device Questions: Has gesture arbitration behavior changed in recent iOS 26 versions when views are inside UIScrollView? Any clarification on whether this is intended behavior or a regression would be greatly appreciated. Thank you.

CarPlay app not receiving data updates when iPhone screen is locked
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.

UIViewRepresentable never dismantled on deletion (MEMORY LEAK)
I have find out that a UIViewRepresentable, even with a simples UIView, seems to never be dismantled when deleted from a ForEach and this can cause serious crashes. In the following example you can observe this behavior by deleting a row from the list. The dismantleUIView function of SomeUIViewRepresentable or the deinit of SomeUIView are never called. Has anyone faced this and found a solution for it? I have also filled a Feedback: FB11979117 class SomeUIView: UIView {     deinit {         print(#function)     } } struct SomeUIViewRepresentable: UIViewRepresentable {     func makeUIView(context: Context) -> SomeUIView {         let uiView = SomeUIView()         uiView.backgroundColor = .systemBlue         return uiView     }     func updateUIView(_ uiView: SomeUIView, context: Context) { }     static func dismantleUIView(_ uiView: SomeUIView, coordinator: Coordinator) {         print(#function)     } } struct Model: Identifiable {     let id = UUID() } struct ContentView: View {     @State var models = [Model(), Model(), Model(), Model(), Model()]     var body: some View {         List {             ForEach(models) { _ in                 SomeUIViewRepresentable()             }             .onDelete {                 models.remove(atOffsets: $0)             }         }     } }

Small Size Icons and NSToolbar on MacOS 12.0 Monterey -- can it work?
I noticing that Monterey defaults to the NSWindowToolbarStyleAutomatic / NSWindowToolbarStyleUnified toolbar style, which suppresses the "use Small Size" menu item and customization checkbox. So I've set the window to use NSWindowToolbarStyleExpanded. However, the toolbar will no longer change to a smaller icon size, as it did in MacOS 10.14, 10.15, and 11.0. I've tried to set the toolbar item sizing to "Automatic" for all of our toolbar icons, but that results in bad positioning in both Regular and Small Size mode -- the height is way too big. The native size of the icon .png files are 128 x 128. What's odd is that if I resize the window with the toolbar to be wider, the NSToolbarItems in the overflow area will be displayed in the toolbar are 128 x 128, where the rest of the toolbar icons get displayed as a 32 x 32 icon. The only way to get it to layout remotely correct is to make the NSToolbarItem to have an explicit minimum size of 24 x 24 and maximum size of 32 x 32. And that USED to allow "small size", but on Monterey, it no longer does. Anyone had any success with small size icons on Monterey?

iOS 26 Liquid Glass not showing
I’m not seeing Liquid Glass on any standard components. A month ago around July 17th I ran our app and saw Liquid Glass on our tab view and various standard components. Those components have not been changed and yet I’m no longer seeing Liquid Glass in our app at all. Components that were previously liquid glass but now are not include TabView and back navigation buttons. I set the UIDesignRequiresCompatibility key explicitly to false but no luck. I was seeing this in Beta 7 and Beta 8 on a real device and on a sim.

In a List row on macOS, changing Image color when row is selected
When using an image in a List item, you sometimes want to tint that image, but only if the item isn’t selected. When it’s selected, you usually want the contents of the list item to be all-white, for contrast. The backgroundProminence Environment value ostensibly exists for this purpose, but in my tests, it never seems to change. Am I doing something wrong? Is there an alternative solution? For instance, this code: import SwiftUI struct ProminentBackgroundInList: View { var body: some View { List(selection: .constant(0)) { ListItem().tag(0) ListItem().tag(1) } } } struct ListItem: View { @Environment(\.backgroundProminence) var backgroundProminence var body: some View { HStack { Image(systemName: "person.fill") .foregroundStyle(backgroundProminence == .standard ? .orange : .primary) Text("Person") } } } #Preview { ProminentBackgroundInList() } Produces this result:

.safeAreaBar(edge: .bottom), animation lag on appear/disappear
When I try to show/hide the content in .safeAreaBar(edge: .bottom), especially the content with a large height, the background animation of the toolbar is very laggy. iOS 26 RC Feedback ID - FB19768797 import SwiftUI struct ContentView: View { @State private var isShown: Bool = false var body: some View { NavigationStack { Button("Toggle") { withAnimation { isShown.toggle() } } ScrollView(.vertical) { ForEach(0..<100) { index in Text("\(index)") .padding() .border(.blue) .background(.blue) .frame(maxWidth: .infinity) } } .scrollEdgeEffectStyle(.soft, for: .bottom) .safeAreaBar(edge: .bottom) { if isShown { Text("Safe area bar") .padding(64) .background(.red) } } } } } #Preview { ContentView() }

hidesBottomBarWhenPushed is bugged on iOS 26
I am using a common UI pattern: UITabBarController as window root, each tab with a separate UINavigationController stack. I want the (bottom!) tab bar to be only visible when the user is at the root of the app and hide it when a detail page is opened. To do that, I used hidesBottomBarWhenPushed on any view controller that would be pushed on my navigation stacks and that worked fine in the past. But with iOS 26, I am seeing several issues: On iOS where when the bottom tab bar is used, when in a details page and navigating back, the tab bar becomes fully visible immediately instead of slowly animating in as it has been in the past. This is particular visible and annoying when using the "swipe to go back" gesture On iPad, the situation is even worse: On iPadOS 18, the tab bar appeared in the navigation controller's navigation bar - no matter if hidesBottomBarWhenPushed was set or not - fine. But now, with iPadOS 26, this top tab bar disappears when a child is pushed. Not only that, it disappears abruptly, without animation, and the Liquid Glass effect on the UIBarButtonItems is broken as well. There is no transition whatsoever, buttons are simply replaced with the new UIBarButtonItems of the pushed view controller once it became fully visible. It gets even worse when swipe-back navigating on iPadOS: As soon as the back transition starts, the tab bar becomes visible again (without animation), covering the title (view) of the UINavigationController. If the swipe-back transition is not completed the tab bar suddenly stays visible When the swipe-back transition is interrupted close to the end of the transition and it goes back to the pushed view controller, the top UIBarButtonItems are showing a visual glitch where the content (text or icon) stays on the area where the tab bar is, while their container (the glass effect) are on the vertically aligned to the title view. I am surprised that I have not found any similar reports of these problems, so I am wondering if I am doing anything wrong or using hidesBottomBarWhenPushed simply isn't recommended or supported any more.

Wrong appearance of decimalPad keyboard in dark mode
Hi. The following code causes UI mismatch on iOS26. Keyboard with type decimalPad and appearance as dark is displayed as popUp with wrong colors. Before iOS26 keyboard was regular with correct color scheme. Please advice either how to make the scheme correct or force to display regular keyboard instead of popup. class ViewController: UIViewController { @IBOutlet weak var textField: UITextField! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. textField.keyboardType = .decimalPad textField.keyboardAppearance = .dark view.backgroundColor = .darkGray } }

List View Drag&Drop Support on iOS
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.

.disabled() doesn't VISUALLY disable buttons inside ToolbarItem on iOS 26 devices
[Also submitted as FB19313064] The .disabled() modifier doesn't visually disable buttons inside a ToolbarItem container on iOS 26.0 (23A5297i) devices. The button looks enabled, but tapping it doesn't trigger the action. When deployment target is lowered to iOS 18 and deployed to an iOS 18 device, it works correctly. It still fails on an iOS 26 device, even with an iOS 18-targeted build. This occurs in both the Simulator and on a physical device. Screen Recording Code struct ContentView: View { @State private var isButtonDisabled = false private var osTitle: String { let version = ProcessInfo.processInfo.operatingSystemVersion return "iOS \(version.majorVersion)" } var body: some View { NavigationStack { VStack { Button("Body Button") { print("Body button tapped") } .buttonStyle(.borderedProminent) .disabled(isButtonDisabled) Toggle("Disable buttons", isOn: $isButtonDisabled) Spacer() } .padding() .navigationTitle("Device: \(osTitle)") .navigationBarTitleDisplayMode(.large) .toolbar { ToolbarItem { Button("Toolbar") { print("Toolbar button tapped") } .buttonStyle(.borderedProminent) .disabled(isButtonDisabled) } } } } }

iOS 18.4 Beta: On iPhones which support Dynamic Island, the AppDelegate method applicationDidBecomeActive() takes longer to be called.
When testing with iOS 18.4 Beta on iPhones which support Dynamic Island, after doing a Face ID authentication, the amount of time it takes before the AppDelegate method applicationDidBecomeActive() is called takes longer than iPhones that do not support Dynamic Island. The time it takes is about double, 1.2 seconds vs 2.5 seconds on average. This does not occur with versions before 18.4 Beta. Anyone else seeing this?

SwiftUI toolbar with IDs crash since macOS 15
I understand this is a known issue, but it’s truly unacceptable that it remains unresolved. Allowing users to customize toolbars is a fundamental macOS feature, and it has been broken since the release of macOS 15. How is it possible that this issue persists even in macOS 15.3 beta (24D5040f)? FB15513599 import SwiftUI struct ContentView: View { @State private var showEditItem = false var body: some View { VStack { VStack { Text("Instructions to reproduce the crash") .font(.title) .padding() Text(""" 1. Click on "Toggle Item" 2. In the menu go to File > New Window 3. In new window, click on "Toggle Item" """) } .padding() Button { showEditItem.toggle() } label: { Text("Toggle Item") } } .padding() .toolbar(id: "main") { ToolbarItem(id: "new") { Button { } label: { Text("New…") } } if showEditItem { ToolbarItem(id: "edit") { Button { } label: { Text("Edit…") } } } } } }

AsyncImage - Cancelled Loading before View is Visible
I have been playing around with the new AsyncImage Api in SwiftUI I am using the initialiser that passes in a closure with the AsyncImagePhase, to view why an image may not load, when I looked at the error that is passed in if the phase is failure, the localised description of the error is "Cancelled" but this is happening before the view is being displayed. I am loading these images in a list, I imagine I am probably doing something which is causing the system to decide to cancel the loading, but I cannot see what. Are there any tips to investigate this further?

Persisting User Settings with SwiftData
I was wondering what the recommended way is to persist user settings with SwiftData? It seems the SwiftData API is focused around querying for multiple objects, but what if you just want one UserSettings object that is persisted across devices say for example to store the user's age or sorting preferences. Do we just create one object and then query for it or is there a better way of doing this? Right now I am just creating: import SwiftData @Model final class UserSettings { var age: Int = 0 var sortAtoZ: Bool = true init(age: Int = 0, sortAtoZ: Bool = true) { self.age = age self.sortAtoZ = sortAtoZ } } In my view I am doing as follows: import SwiftUI import SwiftData struct SettingsView: View { @Environment(\.modelContext) var context @Query var settings: [UserSettings] var body: some View { ForEach(settings) { setting in let bSetting = Bindable(setting) Toggle("Sort A-Z", isOn: bSetting.sortAtoZ) TextField("Age", value: bSetting.age, format: .number) } .onAppear { if settings.isEmpty { context.insert(UserSettings(age: 0, sortAtoZ: true)) } } } } Unfortunately, there are two issues with this approach: I am having to fetch multiple items when I only ever want one. Sometimes when running on a new device it will create a second UserSettings while it is waiting for the original one to sync from CloudKit. AppStorage is not an option here as I am looking to persist for the user across devices and use CloudKit syncing.

SwiftUI navigationTransition(.zoom) glitches during interactive swipe-back
Hi everyone 👋 I’m fairly new to iOS development and I’ve been stuck on a SwiftUI issue for a while now, so I’m hoping someone here can spot what I’m doing wrong. I’m using navigationTransition(.zoom) together with matchedTransitionSource to animate navigation between views. The UI consists of a grid of items (currently a LazyVGrid, though the issue seems unrelated to laziness). Tapping an item zooms it into its detail view, which is structurally the same view type and can contain further items. All good expect that interactive swipe-back sometimes causes the item to disappear from the grid once the parent view is revealed. This only happens when dismissing via the drag gesture; it does not occur when using the back button. I’ve attached a short demo showing the issue and the Swift file containing the relevant view code. Is there something obvious I’m doing wrong with navigationTransition / matchedTransitionSource, or is this a known limitation or bug with interactive swipe-back? Thanks in advance. import SwiftUI struct TestFileView: View { @Namespace private var ns: Namespace.ID let nodeName: String let children: [String] let pathPrefix: String private func transitionID(for childName: String) -> String { "Zoom-\(pathPrefix)->\(childName)" } private let columns = Array(repeating: GridItem(.flexible(), spacing: 12), count: 3) var body: some View { ScrollView { VStack(alignment: .leading, spacing: 12) { Text(nodeName) .font(.title.bold()) .padding(.bottom, 6) LazyVGrid(columns: columns, spacing: 12) { ForEach(children, id: \.self) { childName in let id = transitionID(for: childName) NavigationLink { TestFileView( nodeName: childName, children: childrenFor(childName), pathPrefix: "\(pathPrefix)/\(childName)" ) .navigationTransition(.zoom(sourceID: id, in: ns)) } label: { TestFileCard(title: childName) .matchedTransitionSource(id: id, in: ns) } .buttonStyle(.plain) } } } .padding() } } private func childrenFor(_ name: String) -> [String] { switch name { case "Lorem": return ["Ipsum", "Dolor", "Sit"] case "Ipsum": return ["Amet", "Consectetur"] case "Dolor": return ["Adipiscing", "Elit", "Sed"] case "Sit": return ["Do", "Eiusmod"] case "Amet": return ["Tempor", "Incididunt", "Labore"] case "Adipiscing": return ["Magna", "Aliqua"] case "Elit": return ["Ut", "Enim", "Minim"] case "Tempor": return ["Veniam", "Quis"] case "Magna": return ["Nostrud", "Exercitation"] default: return [] } } } struct TestFileCard: View { let title: String var body: some View { VStack(alignment: .leading, spacing: 8) { Image(systemName: "square.stack.3d.up") .symbolRenderingMode(.hierarchical) .font(.headline) Text(title) .font(.subheadline.weight(.semibold)) .lineLimit(2) .minimumScaleFactor(0.85) Spacer(minLength: 0) } .padding(12) .frame(maxWidth: .infinity, minHeight: 90, alignment: .topLeading) .background(.thinMaterial, in: RoundedRectangle(cornerRadius: 14, style: .continuous)) } } private struct TestRoot: View { var body: some View { NavigationStack { TestFileView( nodeName: "Lorem", children: ["Ipsum", "Dolor", "Sit"], pathPrefix: "Lorem" ) } } } #Preview { TestRoot() }

OTP AutoFill Fails to Distribute Code Across Multiple UITextFields on iOS 26.x
Issue Summary: On iOS 26.0.1 to 26.3, apps using multiple UITextFields for OTP input face a critical issue where the system autofill pastes the entire OTP string into a single text field, usually the focused one, rather than splitting digits across fields. Delegate events like textDidChange: do not trigger consistently on autofill, breaking existing input handling logic. Expected Behavior: OTP autofill should distribute each digit correctly across all OTP UITextFields. Delegate or control events should fire on autofill to enable manual handling. (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { if (string.length > 1) { // Autofill detected - distribute OTP manually for (int i = 0; i < string.length && i < self.arrayOTPText.count; i++) { UITextField *field = self.arrayOTPText[i]; field.text = [NSString stringWithFormat:@"%c", [string characterAtIndex:i]]; } UITextField *lastField = self.arrayOTPText[string.length - 1]; [lastField becomeFirstResponder]; return NO; } // Handle normal single character or deletion input here return YES; } // // Setup UITextFields - set .oneTimeCode on first field only for (int i = 0; i < self.arrayOTPText.count; i++) { UITextField *field = self.arrayOTPText[i]; field.delegate = self; if (@available(iOS 12.0, *)) { field.textContentType = (i == 0) ? UITextContentTypeOneTimeCode : UITextContentTypeNone; } } What We’ve Tried: Setting textContentType properly. Handling OTP distribution in delegate method. Verifying settings and keyboard use. Testing on multiple iOS 26.x versions. Impact: Major usability degradation during OTP entry. Forces fragile workarounds. Inconsistent autofill reduces user confidence. Request: Request Apple fix OTP autofill to natively support multi-field UITextField OTP input or provide enhanced delegate callbacks for consistent behavior. Did any one face this issue in recent time with iOS 26.0.1 to 26.3 beta version

If the swipe-back transition is not completed the tab bar suddenly stays visible When the swipe-back transition is interrupted close to the end of the transition and it goes back to the pushed view controller, the top UIBarButtonItems are showing a visual glitch where the content (text or icon) stays on the area where the tab bar is, while their container (the glass effect) are on the vertically aligned to the title view. I am surprised that I have not found any similar reports of these problems, so I am wondering if I am doing anything wrong or using hidesBottomBarWhenPushed simply isn't recommended or supported any more.

Wrong appearance of decimalPad keyboard in dark mode
Hi. The following code causes UI mismatch on iOS26. Keyboard with type decimalPad and appearance as dark is displayed as popUp with wrong colors. Before iOS26 keyboard was regular with correct color scheme. Please advice either how to make the scheme correct or force to display regular keyboard instead of popup. class ViewController: UIViewController { @IBOutlet weak var textField: UITextField! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. textField.keyboardType = .decimalPad textField.keyboardAppearance = .dark view.backgroundColor = .darkGray } }

Issue with preselecting images on iOS 26.1 in photo library
I have checked the sample project from the documentation page and noticed there is an issue with image/images not being preselected. The issue happens on iOS 26.1 and above (checked iOS 26.2 beta). I couldn't find any change to the PhotoPicker in the documentation.

List View Drag&Drop Support on iOS
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.

.disabled() doesn't VISUALLY disable buttons inside ToolbarItem on iOS 26 devices
[Also submitted as FB19313064] The .disabled() modifier doesn't visually disable buttons inside a ToolbarItem container on iOS 26.0 (23A5297i) devices. The button looks enabled, but tapping it doesn't trigger the action. When deployment target is lowered to iOS 18 and deployed to an iOS 18 device, it works correctly. It still fails on an iOS 26 device, even with an iOS 18-targeted build. This occurs in both the Simulator and on a physical device. Screen Recording Code struct ContentView: View { @State private var isButtonDisabled = false private var osTitle: String { let version = ProcessInfo.processInfo.operatingSystemVersion return "iOS \(version.majorVersion)" } var body: some View { NavigationStack { VStack { Button("Body Button") { print("Body button tapped") } .buttonStyle(.borderedProminent) .disabled(isButtonDisabled) Toggle("Disable buttons", isOn: $isButtonDisabled) Spacer() } .padding() .navigationTitle("Device: \(osTitle)") .navigationBarTitleDisplayMode(.large) .toolbar { ToolbarItem { Button("Toolbar") { print("Toolbar button tapped") } .buttonStyle(.borderedProminent) .disabled(isButtonDisabled) } } } } }

hidesBottomBarWhenPushed in iOS 26
It appears that hidesBottomBarWhenPushed no longer works in iOS 26 Beta 1. Is it supposed to work, is it going away or is there a alternate behavior we should be using?

iOS 18.4 Beta: On iPhones which support Dynamic Island, the AppDelegate method applicationDidBecomeActive() takes longer to be called.
When testing with iOS 18.4 Beta on iPhones which support Dynamic Island, after doing a Face ID authentication, the amount of time it takes before the AppDelegate method applicationDidBecomeActive() is called takes longer than iPhones that do not support Dynamic Island. The time it takes is about double, 1.2 seconds vs 2.5 seconds on average. This does not occur with versions before 18.4 Beta. Anyone else seeing this?

SwiftUI toolbar with IDs crash since macOS 15
I understand this is a known issue, but it’s truly unacceptable that it remains unresolved. Allowing users to customize toolbars is a fundamental macOS feature, and it has been broken since the release of macOS 15. How is it possible that this issue persists even in macOS 15.3 beta (24D5040f)? FB15513599 import SwiftUI struct ContentView: View { @State private var showEditItem = false var body: some View { VStack { VStack { Text("Instructions to reproduce the crash") .font(.title) .padding() Text(""" 1. Click on "Toggle Item" 2. In the menu go to File > New Window 3. In new window, click on "Toggle Item" """) } .padding() Button { showEditItem.toggle() } label: { Text("Toggle Item") } } .padding() .toolbar(id: "main") { ToolbarItem(id: "new") { Button { } label: { Text("New…") } } if showEditItem { ToolbarItem(id: "edit") { Button { } label: { Text("Edit…") } } } } } }

AsyncImage - Cancelled Loading before View is Visible
I have been playing around with the new AsyncImage Api in SwiftUI I am using the initialiser that passes in a closure with the AsyncImagePhase, to view why an image may not load, when I looked at the error that is passed in if the phase is failure, the localised description of the error is "Cancelled" but this is happening before the view is being displayed. I am loading these images in a list, I imagine I am probably doing something which is causing the system to decide to cancel the loading, but I cannot see what. Are there any tips to investigate this further?

Persisting User Settings with SwiftData
I was wondering what the recommended way is to persist user settings with SwiftData? It seems the SwiftData API is focused around querying for multiple objects, but what if you just want one UserSettings object that is persisted across devices say for example to store the user's age or sorting preferences. Do we just create one object and then query for it or is there a better way of doing this? Right now I am just creating: import SwiftData @Model final class UserSettings { var age: Int = 0 var sortAtoZ: Bool = true init(age: Int = 0, sortAtoZ: Bool = true) { self.age = age self.sortAtoZ = sortAtoZ } } In my view I am doing as follows: import SwiftUI import SwiftData struct SettingsView: View { @Environment(\.modelContext) var context @Query var settings: [UserSettings] var body: some View { ForEach(settings) { setting in let bSetting = Bindable(setting) Toggle("Sort A-Z", isOn: bSetting.sortAtoZ) TextField("Age", value: bSetting.age, format: .number) } .onAppear { if settings.isEmpty { context.insert(UserSettings(age: 0, sortAtoZ: true)) } } } } Unfortunately, there are two issues with this approach: I am having to fetch multiple items when I only ever want one. Sometimes when running on a new device it will create a second UserSettings while it is waiting for the original one to sync from CloudKit. AppStorage is not an option here as I am looking to persist for the user across devices and use CloudKit syncing.

SwiftUI navigationTransition(.zoom) glitches during interactive swipe-back
Hi everyone 👋 I’m fairly new to iOS development and I’ve been stuck on a SwiftUI issue for a while now, so I’m hoping someone here can spot what I’m doing wrong. I’m using navigationTransition(.zoom) together with matchedTransitionSource to animate navigation between views. The UI consists of a grid of items (currently a LazyVGrid, though the issue seems unrelated to laziness). Tapping an item zooms it into its detail view, which is structurally the same view type and can contain further items. All good expect that interactive swipe-back sometimes causes the item to disappear from the grid once the parent view is revealed. This only happens when dismissing via the drag gesture; it does not occur when using the back button. I’ve attached a short demo showing the issue and the Swift file containing the relevant view code. Is there something obvious I’m doing wrong with navigationTransition / matchedTransitionSource, or is this a known limitation or bug with interactive swipe-back? Thanks in advance. import SwiftUI struct TestFileView: View { @Namespace private var ns: Namespace.ID let nodeName: String let children: [String] let pathPrefix: String private func transitionID(for childName: String) -> String { "Zoom-\(pathPrefix)->\(childName)" } private let columns = Array(repeating: GridItem(.flexible(), spacing: 12), count: 3) var body: some View { ScrollView { VStack(alignment: .leading, spacing: 12) { Text(nodeName) .font(.title.bold()) .padding(.bottom, 6) LazyVGrid(columns: columns, spacing: 12) { ForEach(children, id: \.self) { childName in let id = transitionID(for: childName) NavigationLink { TestFileView( nodeName: childName, children: childrenFor(childName), pathPrefix: "\(pathPrefix)/\(childName)" ) .navigationTransition(.zoom(sourceID: id, in: ns)) } label: { TestFileCard(title: childName) .matchedTransitionSource(id: id, in: ns) } .buttonStyle(.plain) } } } .padding() } } private func childrenFor(_ name: String) -> [String] { switch name { case "Lorem": return ["Ipsum", "Dolor", "Sit"] case "Ipsum": return ["Amet", "Consectetur"] case "Dolor": return ["Adipiscing", "Elit", "Sed"] case "Sit": return ["Do", "Eiusmod"] case "Amet": return ["Tempor", "Incididunt", "Labore"] case "Adipiscing": return ["Magna", "Aliqua"] case "Elit": return ["Ut", "Enim", "Minim"] case "Tempor": return ["Veniam", "Quis"] case "Magna": return ["Nostrud", "Exercitation"] default: return [] } } } struct TestFileCard: View { let title: String var body: some View { VStack(alignment: .leading, spacing: 8) { Image(systemName: "square.stack.3d.up") .symbolRenderingMode(.hierarchical) .font(.headline) Text(title) .font(.subheadline.weight(.semibold)) .lineLimit(2) .minimumScaleFactor(0.85) Spacer(minLength: 0) } .padding(12) .frame(maxWidth: .infinity, minHeight: 90, alignment: .topLeading) .background(.thinMaterial, in: RoundedRectangle(cornerRadius: 14, style: .continuous)) } } private struct TestRoot: View { var body: some View { NavigationStack { TestFileView( nodeName: "Lorem", children: ["Ipsum", "Dolor", "Sit"], pathPrefix: "Lorem" ) } } } #Preview { TestRoot() }

OTP AutoFill Fails to Distribute Code Across Multiple UITextFields on iOS 26.x
Issue Summary: On iOS 26.0.1 to 26.3, apps using multiple UITextFields for OTP input face a critical issue where the system autofill pastes the entire OTP string into a single text field, usually the focused one, rather than splitting digits across fields. Delegate events like textDidChange: do not trigger consistently on autofill, breaking existing input handling logic. Expected Behavior: OTP autofill should distribute each digit correctly across all OTP UITextFields. Delegate or control events should fire on autofill to enable manual handling. (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { if (string.length > 1) { // Autofill detected - distribute OTP manually for (int i = 0; i < string.length && i < self.arrayOTPText.count; i++) { UITextField *field = self.arrayOTPText[i]; field.text = [NSString stringWithFormat:@"%c", [string characterAtIndex:i]]; } UITextField *lastField = self.arrayOTPText[string.length - 1]; [lastField becomeFirstResponder]; return NO; } // Handle normal single character or deletion input here return YES; } // // Setup UITextFields - set .oneTimeCode on first field only for (int i = 0; i < self.arrayOTPText.count; i++) { UITextField *field = self.arrayOTPText[i]; field.delegate = self; if (@available(iOS 12.0, *)) { field.textContentType = (i == 0) ? UITextContentTypeOneTimeCode : UITextContentTypeNone; } } What We’ve Tried: Setting textContentType properly. Handling OTP distribution in delegate method. Verifying settings and keyboard use. Testing on multiple iOS 26.x versions. Impact: Major usability degradation during OTP entry. Forces fragile workarounds. Inconsistent autofill reduces user confidence. Request: Request Apple fix OTP autofill to natively support multi-field UITextField OTP input or provide enhanced delegate callbacks for consistent behavior. Did any one face this issue in recent time with iOS 26.0.1 to 26.3 beta version
