UIActivity is not annotated with concurrency information. Does anyone know if subclasses you create will always run on the @MainActor ?

My document-based UIKit app can open plain text files such as .txt files. When tapping a particular button I want to be able to select a folder, but when using the code below, the document picker allows me to select folders as well as .txt files: class DocumentViewController: UIDocumentViewController, UIDocumentPickerDelegate { override func viewDidAppear(_ animated: Bool) { let documentPicker = UIDocumentPickerViewController(forOpeningContentTypes: [.folder]) documentPicker.delegate = self present(documentPicker, animated: true) } } If I remove the text file entry from the Info.plist's document types list, it works as expected. Is this a bug and if yes, is there a workaround? <key>CFBundleDocumentTypes</key> <array> <dict> <key>CFBundleTypeName</key> <string>Text</string> <key>CFBundleTypeRole</key> <string>Editor</string> <key>LSHandlerRank</key> <string>Default</string> <key>LSItemContentTypes</key> <array> <string>public.text</string> </array> </dict> </array> I created FB22254960.

I want to create SplitView App for macOS like Apple Mail. Is it possible using swiftUI NavigationSplitView or should I use AppKit to achieve it. I want exact toolbar buttons also. Filter button will be in Invoice list pane and other buttons in the details pane. Also, I want details pane completely collapsable(just like in Mail app).

I'm building a macOS app with two separate NSPanel windows, both using the new liquid glass material (NSVisualEffectView / macOS 26). The UI intentionally has two separate floating panels visible at the same time. The problem: only the key window displays the active liquid glass appearance. The non-key panel always renders with the inactive/foggy appearance, even with: NSWindowStyleMaskNonactivatingPanel canBecomeKeyWindow = false orderFrontRegardless() addChildWindow(_:ordered:) Is there any way — documented or otherwise — to force the active liquid glass appearance on a non-key NSPanel? Or is this fundamentally a compositor-level restriction? If it's impossible with two separate windows, is there an alternative approach to achieve two visually separate liquid glass boxes that both appear active simultaneously?

My basic need is that I have unicode symbols which compose to a marked musical note. I'd like that note to be rotated upside down. Obviously, I could do this by sticking each into a View of some sort, and applying rotation effect. Indeed, I've done this for the part of my app where these notes are the labels of Buttons. However, the results of pressing the buttons need to be displayed, and on most of my app, this is a simple String. However, I can find no way to rotate individual glyphs of a String. And I'm not keen to write a compositor to layout View like glyphs in a String. Is there a way to make a font by finding individual glyphs, doing the transform, and packaging them into a new specialized font, without needed to use an external Font making application?

On macOS 26, how do you support the Preferred Text Size value as defined in the Accessibility Settings? Historically, "Dynamic Type" has not been available on macOS. However, the user has some control over text size through the Accessibility Settings. On macOS 26, a small subset of applications are honouring changes to that value include Finder, Mail, and sidebars in many applications. Dynamic sizing in table views has been available on macOS for awhile. But Mail.app, in particular, is also adjusting the font sizes used in the message's body pane while the Finder is adjusting font sizes used for Desktop icons. I can't find an NSNotification that is fired when the user adjusts the Accessibility Text Size slider, nor can I find an API to read the current value. NSFont.preferredFont(forTextStyle:options:) looks promising but the fonts returned do not appear to take the user's Accessibility setting into account. (Nor do they update dynamically.) SwiftUI's Text("Apple").font(.body) performs similarly to NSFont in that it does respect the style, but it does not honour dynamic sizing. NSFontDescriptor has a bunch of interesting methods, but none that seem to apply to Accessibility Text Size. Given an AppKit label: let label = NSTextField(labelWithString: "AppKit") label.font = NSFont.preferredFont(forTextStyle: .body) Or a SwiftUI label: Text("SwiftUI").font(.body) How do I make either of them responsive to the user's Text Size setting under Accessibility? Note this is on macOS 26 / Xcode 26. I realize there have been some previous forum posts related to this issue but hoping that things might have improved since then.

[Submitted as FB22226720] For a NavigationStack destination, applying .navigationBarBackButtonHidden(true) hides the back button and also disables the interactive left-edge back gesture when using the standard push navigation transition. However, when the destination uses .navigationTransition(.zoom), the back button is hidden but the left-edge back gesture is still available—it can still be dismissed even though back is intentionally suppressed. This creates inconsistent behavior between navigation transition styles. navigationBarBackButtonHidden(_:) works with a standard push transition, but not with .navigationTransition(.zoom). In the code below, .interactiveDismissDisabled(true) is also applied as another attempt to suppress the back-swipe gesture, but it has no effect. As a result, there’s currently no clean way to prevent back navigation when using the zoom transition. REPRO STEPS Create an iOS project then replace ContentView with code below, build and run. Leave nav type set to List Push. Open an item. Verify there is no back button, then try the left-edge back gesture. Return to the root view. Change nav type to Grid Zoom. Open an item. Verify there is no back button, then try the left-edge back gesture. ACTUAL In List Push mode, the left-edge back gesture is prevented. In Grid Zoom mode, the back button is hidden, but the left-edge back gesture still works and returns to the previous view. EXPECTED Behavior should be consistent across navigation transition styles. If this configuration is meant to suppress interactive backward navigation for a destination, it should also suppress the left-edge back gesture when using .navigationTransition(.zoom). SCREEN RECORDING SAMPLE CODE struct ContentView: View { private enum NavigationMode: String, CaseIterable { case listPush = "List Push" case gridZoom = "Grid Zoom" } @Namespace private var namespace @State private var navigationMode: NavigationMode = .listPush private let colors: [Color] = [.red, .blue] var body: some View { NavigationStack { VStack(spacing: 16) { Picker("Navigation Type", selection: $navigationMode) { ForEach(NavigationMode.allCases, id: \.self) { mode in Text(mode.rawValue).tag(mode) } } .pickerStyle(.segmented) if navigationMode == .gridZoom { HStack { ForEach(colors.indices, id: \.self) { index in NavigationLink(value: index) { VStack { RoundedRectangle(cornerRadius: 14) .fill(colors[index]) .frame(height: 120) Text("Grid Item \(index + 1)") .font(.subheadline.weight(.medium)) } .padding(12) .frame(maxWidth: .infinity) .background(.quaternary.opacity(0.25), in: RoundedRectangle(cornerRadius: 16)) .matchedTransitionSource(id: index, in: namespace) } .buttonStyle(.plain) } } } else { ForEach(colors.indices, id: \.self) { index in NavigationLink(value: index) { HStack { Circle() .fill(colors[index]) .frame(width: 24, height: 24) Text("List Item \(index + 1)") Spacer() Image(systemName: "chevron.right") .foregroundStyle(.secondary) } .padding() .background(.quaternary.opacity(0.25), in: RoundedRectangle(cornerRadius: 12)) } .buttonStyle(.plain) } } Spacer() } .padding(20) .navigationTitle("Prevent Back Swipe") .navigationSubtitle("Compare Grid Zoom vs List Push") .navigationDestination(for: Int.self) { index in if navigationMode == .gridZoom { DetailView(color: colors[index]) .navigationTransition(.zoom(sourceID: index, in: namespace)) } else { DetailView(color: colors[index]) } } } } } private struct DetailView: View { @Environment(\.dismiss) private var dismiss let color: Color var body: some View { ZStack { color.ignoresSafeArea() Text("Try left-edge swipe back") .font(.title.bold()) .multilineTextAlignment(.center) .padding(.horizontal, 24) } .navigationBarBackButtonHidden(true) .interactiveDismissDisabled(true) .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Close", action: dismiss.callAsFunction) } } } }

I need to validate whether specific menu items are correctly enabled/disabled. The XCUIAutomation elements for my menu items do not appear in the tree shown by displaying the XCUIApplication object in the debugger when building and testing the iPadOS version of my application. When running the application in an iPad simulator, I can make the menu bar appear by swiping down. The testing works as expected for the MacOS build and test. I did try to use the recording feature, but was not successful in creating a series of commands that worked for a test run.

Context: Xcode 26.3, iOS 18.7.6 on iPhone Xs In this iOS app, I call UIActivityViewController to let user Airdrop files from the app. When trying to send a URL whose file name contains some characters like accentuated (-, é, '), the transfer fails. Removing those characters makes it work without problem. The same app running on Mac (in iPad mode) works with both cases. I also noticed that even when airdrop fails, there is no error reported by activityVC.completionWithItemsHandler = { activity, success, items, error in } Are those known issues ?

There is a long-standing, structural issue with the iPadOS Korean IME when using a hardware keyboard. The IME forcibly intercepts the " (quote) keydown event and injects Unicode smart/curved quotes (“ or ”) directly into the text field. This hardcoded behavior ignores both: User Settings: The global "Smart Punctuation" toggle in [Settings > General > Keyboard] is completely ignored. Developer APIs: Setting UITextInputTraits.smartQuotesType = .no on a UITextView or UITextField has absolutely no effect when the Korean keyboard is active. Steps to Reproduce: Set smartQuotesType = .no on a standard UITextView. Connect a hardware keyboard. Switch input language to English -> Press the quote key. (Result: ASCII straight quote " - Correct behavior) Switch input language to Korean -> Press the quote key. (Result: Unicode curved quote “ - Incorrect behavior) Impact on Developers & Users: Because the OS IME forcefully injects the curved Unicode character before the app can process the raw key event, developers building code editors, markdown editors, or specific word processors (like Google Docs) cannot prevent this behavior. We cannot provide a standard text-editing experience for Korean users without forcing them to manually toggle their keyboard language to English just to type a straight quote. Expected Behavior: The Korean hardware keyboard IME must respect UITextInputTraits.smartQuotesType and the global OS toggle. Please provide a mechanism for developers and users to bypass this forced CJK typography rule.

Device: iPhone 17 Pro Max iOS version: iOS 26.3 CarPlay type: Wired We are encountering two intermittent UI issues in CarPlay when running our music application. The problems occur occasionally and cannot be recovered without restarting the device. Issue 1: CPListImageRowItem image not displaying On the CarPlay home page, some images occasionally fail to appear. Implementation details: The list is updated using CPListTemplate.updateSections. Each item is a CPListImageRowItem. On iOS versions below 26, images are updated using updateImages. On iOS 26, images are provided through CPListImageRowItem.elements, where each element is a CPListImageRowItemRowElement. Observed behavior: Logs confirm that the data is correctly provided. However, in failing cases the CPListImageRowItemRowElement appears with both title and subtitle equal to nil. The image is not rendered in the UI even though the item exists. Issue 2: Now Playing bottom buttons occasionally missing On the Now Playing screen, the bottom control buttons sometimes fail to appear. Implementation details: Buttons are updated using CPNowPlayingTemplate.updateNowPlayingButtons. The buttons are instances of CPNowPlayingImageButton. Observed behavior: Occasionally the buttons are not displayed. Once this occurs, the UI does not recover. Restarting the phone immediately resolves the issue. Additional observations The issue appears to occur intermittently. Once triggered, it persists until the device is rebooted. Similar behavior has been observed in other music apps (for example, QQ Music). Questions Are there known CarPlay UI rendering issues related to CPListImageRowItem or CPNowPlayingTemplate in recent iOS versions? Is there any recommended workaround or lifecycle handling that might prevent these UI elements from failing to render? Any guidance would be greatly appreciated.

I have faced a problem while I was trying to implement a reorder drag & drop view. I found that when I add any kind of .gesture or .simultaneousGesture, a ScrollView's scrolling behavior wasn't working properly (does not scroll at all). ScrollView(.vertical, showsIndicators: false) { ForEach($items) { $item in EditorCard(stepDetails: item) .simultaneousGesture( customCombinedGesture(item) ) } } This ScrollView worked fine with .onLongPressGesture(), however, I wanted to use custom gestures sequences.

[Submitted as FB22200608] With Increase Contrast turned on, the selected row highlight in a List behaves inconsistently between light and dark appearance on iPad. In light appearance the blue selection highlight correctly becomes darker, but in dark appearance it becomes lighter instead. The text contrast ratio drops from about 3:1 to about 1.5:1, well below accessibility guidelines. This reproduces both in the simulator and on a physical device. The sample uses a standard SwiftUI List inside NavigationSplitView with built-in selection styling. No custom colors or styling are applied. REPRO STEPS Create a new Multiplatform project. Replace ContentView with code below. Build and run on iPad. Select an item in the list. Turn on Dark appearance (Cmd-Shift-A in Simulator). Turn on Increase Contrast (Cmd-Control-Shift-A in Simulator). Observe the selected row highlight. ACTUAL In light appearance, the blue selection highlight becomes darker when Increase Contrast is on, improving contrast as expected. In dark appearance, the blue selection highlight becomes lighter when Increase Contrast is on, reducing contrast between the selection background and the white text. EXPECTED Increase Contrast should consistently increase contrast. In dark appearance, the selection highlight should become darker—or otherwise increase contrast with the foreground text—not lighter. SAMPLE CODE struct ContentView: View { @State private var selection: String? var body: some View { NavigationSplitView { Text("Sidebar") } content: { List(selection: $selection) { Text("Item One") .tag("One") Text("Item Two") .tag("Two") } } detail: { if let selection { Text(selection) } else { Text("Select an item") } } } } SCREEN RECORDING CONTACTS The Contacts app behaves correctly. When Increase Contrast is turned on, the selection blue becomes darker, improving contrast. PASSWORDS The Passwords app, however, exhibits the issue. With Increase Contrast turned on, the selection blue becomes lighter instead of darker, reducing contrast.

When using ShareLink in SwiftUI to share an image, the “Save Image” action dismisses not only the share sheet but also the presenting SwiftUI view. The behavior differs depending on whether the photo library permission alert appears. Observed behavior: The first time the user taps Save Image, the system permission alert appears. After granting permission, the image saves successfully and the share sheet dismisses normally. On subsequent attempts, the image is saved successfully, but both the share sheet and the presenting view are dismissed unexpectedly. Expected behavior: After saving the image, only the share sheet should dismiss. The presenting SwiftUI view should remain visible. Steps to Reproduce Present a SwiftUI view using .sheet. Inside that view, add a ShareLink configured to export a PNG image using Transferable. Tap the ShareLink button. Choose Save Image. Grant permission the first time (if prompted). Repeat the action. Result: On subsequent saves, the share sheet dismisses and the presenting view is dismissed as well. Sample code ` internal import System import UniformTypeIdentifiers import SwiftUI struct RootView: View { @State private var isPresented: Bool = false var body: some View { ZStack { Color.white Button("Show parent view") { isPresented = true } } .sheet(isPresented: $isPresented) { ParentView() } } } struct ParentView: View { @State private var isPresented: Bool = false var body: some View { NavigationStack { ZStack { Color.red.opacity(0.5) } .toolbar { ToolbarItem() { let name = "\(UUID().uuidString)" let image = UIImage(named: "after")! return ShareLink( item: ShareableImage(image: image, fileName: name), preview: SharePreview( name, image: Image(uiImage: image) ) ) { Image(uiImage: UIImage(resource: .Icons.share24)) .resizable() .foregroundStyle(Color.black) .frame(width: 24, height: 24) } } } } } } struct ShareableImage: Transferable { let image: UIImage let fileName: String static var transferRepresentation: some TransferRepresentation { FileRepresentation(exportedContentType: .png) { item in let fileURL = FileManager.default.temporaryDirectory .appendingPathComponent(item.fileName) .appendingPathExtension("png") guard let data = item.image.pngData() else { throw NSError(domain: "ImageEncodingError", code: 0) } try data.write(to: fileURL) return SentTransferredFile(fileURL) } } } `

ShareLink works fine except for save image action which dismiss the presenting view first time system shows the premission alert so image get saved without any problem but for the next saves image get saved then share sheet dismiss and also presenting view dismiss as well here is a sample code ` internal import System import UniformTypeIdentifiers import SwiftUI struct RootView: View { @State private var isPresented: Bool = false var body: some View { ZStack { Color.white Button("Show parent view") { isPresented = true } } .sheet(isPresented: $isPresented) { ParentView() } } } struct ParentView: View { @State private var isPresented: Bool = false var body: some View { NavigationStack { ZStack { Color.red.opacity(0.5) } .toolbar { ToolbarItem() { let name = "\(UUID().uuidString)" let image = UIImage(named: "after")! return ShareLink( item: ShareableImage(image: image, fileName: name), preview: SharePreview( name, image: Image(uiImage: image) ) ) { Image(uiImage: UIImage(resource: .Icons.share24)) .resizable() .foregroundStyle(Color.black) .frame(width: 24, height: 24) } } } } } } struct ShareableImage: Transferable { let image: UIImage let fileName: String static var transferRepresentation: some TransferRepresentation { FileRepresentation(exportedContentType: .png) { item in let fileURL = FileManager.default.temporaryDirectory .appendingPathComponent(item.fileName) .appendingPathExtension("png") guard let data = item.image.pngData() else { throw NSError(domain: "ImageEncodingError", code: 0) } try data.write(to: fileURL) return SentTransferredFile(fileURL) } } } `

Subject: Cross-Domain Access Behaviour in WKWebView – Clarification Required Description: We are facing a cross-domain issue in our iOS application where WKWebView loads content from one domain and attempts to access resources/data from another domain. Current Setup: App Platform: iOS WebView: WKWebView iOS Version: 26 Primary Domain: *.franconnectqa.net Data/Analytics Domain: analytics.franconnectdev.net SSL: Valid certificates configured ATS: Enabled Issue: When WKWebView loads content from franconnectqa.net, it attempts to access resources or analytics from analytics.franconnectdev.net, resulting in cross-domain restrictions. We would like to understand: Does WKWebView support cross-domain resource access by default? Are there any configuration settings that allow controlled cross-domain access? Are there known limitations regarding cookies, local storage, or session sharing across domains? Does WKWebView enforce additional restrictions beyond standard browser CORS policies? Are there recommended best practices for handling cross-domain scenarios in WKWebView? Expected Behavior: We want to determine whether: Cross-domain access is supported under certain configurations, OR The recommended approach is to align all resources under the same domain. Kindly provide guidance on the supported architecture and any configuration recommendations.

I'm using UITabBarAppearance to customize my TabBar in a SwiftUI app. The customization works perfectly on iOS 18 and earlier, but after updating to iOS 26, the unselected tab items no longer respect my color settings - they just appear black (they are on a white background).Here's my simplified setup: struct ContentView: View { var body: some View { TabView { Text("Home") .tabItem { Image(systemName: "house") Text("Home") } .tag(0) Text("Settings") .tabItem { Image(systemName: "gear") Text("Settings") } .tag(1) } .onAppear { setupTabBarAppearance() } } private func setupTabBarAppearance() { let appearance = UITabBarAppearance() appearance.configureWithOpaqueBackground() let itemAppearance = UITabBarItemAppearance() // These settings work for selected items itemAppearance.selected.iconColor = .systemBlue itemAppearance.selected.titleTextAttributes = [ .font: UIFont.systemFont(ofSize: 10), .foregroundColor: UIColor.systemBlue ] // These settings STOPPED working on iOS 26 for unselected items itemAppearance.normal.iconColor = .gray itemAppearance.normal.titleTextAttributes = [ .font: UIFont.systemFont(ofSize: 10), .foregroundColor: UIColor.gray ] appearance.stackedLayoutAppearance = itemAppearance appearance.inlineLayoutAppearance = itemAppearance appearance.compactInlineLayoutAppearance = itemAppearance UITabBar.appearance().standardAppearance = appearance UITabBar.appearance().scrollEdgeAppearance = appearance } }

I’m developing a text editor that provides a line number view. This view is placed next to the NSScrollView that contains the main text view, rather than inside the scroll view. The line number view updates its drawing in sync with the NSScrollView’s scrolling and text editing in the NSTextView, so it can display the correct line numbers. This approach worked fine through macOS 15, but on macOS 26 with Liquid Glass, the line numbers end up being drawn without the expected blur/soft edge effect under the window toolbar area. In AppKit, some view controllers provide APIs to switch edge effects between soft/hard, but I can’t find any API to control this for the window toolbar region. I considered simply not drawing the numbers outside the content area, but if possible I’d like to apply the Tahoe-style soft edge effect instead. Does anyone have ideas? Is this currently impossible, meaning the only option is to file a feedback/API request? Also, for various reasons, the traditional approach of implementing line numbers by subclassing NSRulerView is difficult for my app.

So I'm in the middle of an asynchronous file operation. I publish an NSProgress and it displays wonderfully in Finder. But it is a folder and while the operation is in progress the user should not be allowed to enter it, modify it, etc, while the work is being done. I want to do this to protect the user from doing something silly. But Finder does not prevent the selection with the published progress. And while it would be kind of dumb to do - the user can just go about adding/removing contents to the folder while it has progress. If I remember correctly publishing an NSProgress did use to prevent the file from being selectable in Finder until either the progress finished or my app is quit (or maybe not)? But now the user is free to select, edit, modify during progress which could cause problems if the user does something unexpectedly silly. Is there a way to mark the file 'unselectable' with the published progress? Thanks in advance.
