In macOS 13.2, the NSTrackingEnabledDuringMouseDrag flag for NSTrackingArea is broken, i.e., mouse-entered and mouse-exited events are not sent during a drag. This problem did not exist in macOS 12. I've filed a bug report, FB11973492, just wondering if anyone knows a workaround.

I've created a custom keyboard and implemented the: class KeyboardViewController: UIInputViewController The imlementation looks like this: override func viewDidLoad() { super.viewDidLoad() var stack = UIStackView() stack.axis = .vertical stack.spacing = 8 stack.translatesAutoresizingMaskIntoConstraints = false stack.distribution = .fill stack.heightAnchor.constraint(equalToConstant: 200).isActive = true .... view.addSubview(stack) NSLayoutConstraint.activate([ stack.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20), stack.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -20), stack.topAnchor.constraint(equalTo: view.topAnchor, constant: 10), stack.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -10) ]) The problem is that the keyboard seems to start showing in the size (I've printed the parent frame): Optional(<UIView: 0x101008480; frame = (0 0; 390 844); autoresize = W+H; layer = <CALayer: 0x600000207b80>>) and than resizes to my given height. But it's not fast enough so that I can see some glitches whenever I switch from another keyboard to my custom keyboard. Is there a way to prevent this resizing or start the keyboard in a given size? This is just not the best user experience.

Hello. In my app, I use RegisterEventHotkey to implement global keyboard shortcuts to trigger actions. Up until macOS Sequoia, I was able to use a keyboard shortcut with option and shift as the modifiers, like option shift 2 (⌥ ⇧ 2). Now, on macOS Sequoia, using RegisterEventHotkey to register a hotkey with those exact modifiers (option and shift), regardless of the key, fails with the error -9868 (eventInternalErr). Is this a documented and wanted change, or is this a bug? Other modifier keys (just command, command option, command shift, command control, control shift, etc), all work. Any insight into this would be appreciated. (Feedback filed: FB15163561) Thank you, Matthias

In a modal dialog, when tabbing to next NSTextField, or programmatically selecting a NSTextField, the NSTextfField that is loosing focus (aka resigning FirstResponder) appears empty in Tahoe 26 ( aka not displaying its content) . The same thing works oK in all systems before Tahoe. Found no workaround this issue which looks to be a Tahoe problem. i have a small app that demonstrate the issue.. but cannot be posted here due to zip format not accepted... i appreciate any help or apple engineer attention to that issue also posted with Evaluation Assistant under #FB21102969 ThX

Hi Is there a way to create a dynamic app clip card experience? I have advanced app clip experiences set up and working fine already and but I am looking to provider a more dynamic experience. For example, my invocation url now is https://mycompany.com/profile/<profile_slug>, this URL shows the app clip card with the title, subheading, and cover image as configured in app store connect which is right. But I would like to show a different title, subheading, and cover image based on the <profile_slug> in the invocation URL. Like we can show the name as the title, job title as the subheading, and profile's banner image as the cover image for the app clip It seems like this is possible as I have seen one company do this for their product. Apple has no mention for such a thing in their documentation from what I have seen. Any help would be appreciated. Thanks

Hi, does anyone know how to enable creating or configuring Near NFC Reader in SwiftUI? I've already added the capability, the permissions in info.plist, the entitlement, and the SwiftUI code, but without success. Here's the example code: class PaymentT2PViewModel: NSObject, ObservableObject { @Published var paymentT2PUIState: PaymentT2PUIState // MARK: - NFC Properties @Published var nfcMessage: String = .empty @Published var isNFCReading: Bool = false private var nfcSession: NFCTagReaderSession? init(paymentT2PUIState: PaymentT2PUIState) { self.paymentT2PUIState = paymentT2PUIState super.init() ) } func startNFCReading() { print("INICIO: startNFCReading llamado") guard NFCTagReaderSession.readingAvailable else { print("ERROR: NFC NO disponible en este dispositivo") Task { @MainActor in self.nfcMessage = "NFC no disponible en este dispositivo" } return } print("NFC disponible, creando sesión...") nfcSession = NFCTagReaderSession( pollingOption: [.iso14443, .iso15693, .iso18092], delegate: self, queue: nil ) print("Sesión creada, configurando mensaje...") nfcSession?.alertMessage = "Acerca la tarjeta al iPhone" nfcSession?.begin() print("Sesión NFC INICIADA - debería aparecer popup") Task { @MainActor in self.isNFCReading = true } } func stopNFCReading() { nfcSession?.invalidate() Task { @MainActor in self.isNFCReading = false } } extension PaymentT2PViewModel: NFCTagReaderSessionDelegate { func tagReaderSession(_ session: NFCTagReaderSession, didInvalidateWithError error: Error) { print("SESIÓN INVALIDADA") print("Error: (error.localizedDescription)") if let readerError = error as?

What am I doing wrong?

The ScreenCaptureKit sample application (https://developer.apple.com/documentation/screencapturekit/capturing-screen-content-in-macos) uses a filter initially set to capture content from the selected display, excluding only the sample application, and excepting no windows: private var contentFilter: SCContentFilter { var filter: SCContentFilter switch captureType { case .display: guard let display = selectedDisplay else { fatalError("No display selected.") } var excludedApps = [SCRunningApplication]() // If a user chooses to exclude the app from the stream, // exclude it by matching its bundle identifier. if isAppExcluded { excludedApps = availableApps.filter { app in Bundle.main.bundleIdentifier == app.bundleIdentifier } } // Create a content filter with excluded apps. filter = SCContentFilter(display: display, excludingApplications: excludedApps, exceptingWindows: []) ....... return filter However, if another application uses the legacy NSWindowSharingType NSWindowSharingNone attribute, that application is initially not included in the captured stream. Only by toggling either the "Capture Type" or "Exclude sample from stream" checkbox does the initially hidden application become visible. Additionally, if the "Stop Capture" button is used followed by "Start Capture", the application using the legacy NSWindowSharingType NSWindowSharingNone attribute is once again hidden from the stream, and is only made visible by toggling either the "Capture Type" or "Exclude sample from stream" checkbox. Does some additional filter element or other SCStream configuration need to be included to verify that all applications, regardless of NSWindowSharingType, are captured using ScreenCaptureKit without requiring manual user interaction/filter refreshing? It seems odd that QuickTime screen recording (using ScreenCaptureKit) immediately captures an application using the NSWindowSharingNone attribute while the ScreenCaptureKit sample application linked above does not. See images below showing the stream preview before and after toggling the "Capture Type" or "Exclude sample from stream" checkbox. Images were taken from a QuickTime screen recording during testing.

Is anyone else experiencing NavigationStack title disappearing in iOS 26? Hey everyone, I just updated to iOS 26 and I'm running into a really frustrating issue with my app. Wondering if anyone else is seeing this or if I'm missing something obvious. What's happening: My navigation titles are completely blank when the app first loads, but then magically appear when I scroll down. It's super weird and makes my app look broken at first glance. My setup: I'm using NavigationStack with some pretty standard stuff: Navigation title with .navigationTitle() A toolbar with a settings button ScrollView content with a gradient background Here's basically what I have: NavigationStack { ScrollView { VStack(spacing: 24) { // My app content here - cards, etc. ForEach(myItems) { item in // Content cards } } .padding() } .background( LinearGradient( gradient: Gradient(colors: [ Color.surfacePrimary, Color.surfacePrimary.opacity(0.95), Color.surfaceSecondary.opacity(0.3) ]), startPoint: .top, endPoint: .bottom ) ) .navigationTitle("My Title") // ← This doesn't show up initially! .toolbar { ToolbarItem(placement: .navigationBarTrailing) { Button("Settings") { // Settings action } } } } The weird part: Works perfectly fine on my iOS 18.6.2 device Completely broken on iOS 26 - blank navigation area As soon as I scroll, the title appears and stays there Happens on both simulator and physical device What I've tried: Double-checking my code (it's identical to what worked before) Testing on multiple devices Different navigation title strings Removing and re-adding the toolbar Has anyone else run into this? I'm thinking it might be an iOS 26 bug with NavigationStack, but I wanted to check if others are seeing it before filing a radar. It's affecting my main landing screens (Tennis, NFL, and Prediction Markets tabs) and honestly looks pretty bad when users first open the app and see blank headers. Temporary fix I found: If anyone else hits this, I discovered that forcing inline titles works as a workaround: .navigationTitle("My Title") .navigationBarTitleDisplayMode(.inline) // This fixes it but kills large titles Obviously not ideal since we lose the nice large title behavior, but at least the titles show up. Questions: Is this happening to anyone else's iOS 26 apps? Any better workarounds that preserve large titles? Should I file this as a radar or is Apple already aware? Really hoping this gets fixed soon - having to choose between broken navigation or losing large titles is pretty frustrating. Thanks for any insights! Anyone else dealing with this NavigationStack nightmare in iOS 26? 😅

On Tahoe NSTextField (and NSTextFieldCell) appears to ignore backgroundColor, drawsBackground, isBezeled, bezelStyle and isBordered properties. Those worked on prior macOS, but not Tahoe. Is there a way to make those properties effective while targeting Tahoe? Note: a slight erratum: backgroundColor has an effect while the text field has first responder status, but the background area is an inset rectangle and I suspect that is a remnant feature and not by design.

Our app was just rejected by Apple because they say the subscription management sheet never loads. It just spins indefinitely. We're using StoreKit's manageSubscriptionsSheet view modifier to present the sheet, and it's always worked for us when testing in SandBox. Has anyone else had this problem? Given that it's Apple's own code that got us rejected, what's our path forward?

I know iPhone Cannot prohibit screenshots, but I have seen someone else's solution, which is to capture a white page instead of the current design page when taking screenshots. I want to use swift implement iPhone The photo generated when taking a screenshot is a white screen, and I don't want my page to be seen by others

Device: iPhone 11 iOS Version: 17.2.1 Frameworks: UIKit, Auto Layout App Behavior: App supports Arabic (RTL). User can switch language in-app. When language is switched, the app sets UIView.appearance().semanticContentAttribute and fully rebuilds the window’s rootViewController. Problem Summary I update the global semantic direction only when the user explicitly switches language inside the app — e.g.: // Only run when user switches language inside the app UIView.appearance().semanticContentAttribute = .forceRightToLeft // or .forceLeftToRight // then rebuild the window's rootViewController I do not change UIView.appearance().semanticContentAttribute during navigation transitions. Despite that, after switching the language (and rebuilding the root), the app sometimes crashes during a subsequent UINavigationController push/pop animation. The crash appears to be caused by UIKit’s Auto Layout engine removing or updating directional constraints while a navigation transition is running.

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)?

[Also submitted as FB20225387] When using a custom SF Symbol that combines a base symbol with a badge, the symbol doesn’t stay vertically centered when displayed in code. The vertical alignment shifts based on the Y offset of the badge. There are two problems with this: The base element shouldn’t move vertically when a badge is added—the badge is meant to add to the symbol, not change its alignment. The badge position should be consistent with system-provided badged symbols, where badges always appear in a predictable spot relative to the corner they're in (usually at X,Y offsets of 90% or 10%). Neither of these behaviors match what’s expected, leading to inconsistent and misaligned symbols in the UI. Screenshot of Problem The ellipsis shifts vertically whenever the badge Y offset is set to anything other than 50%. Even at a 90/10 offset, it still doesn’t align with the badge position of the system "envelope.badge" symbol. SF Symbols Export This seem to be a SwiftUI issue since both the export from SF Symbols is correctly centered: Xcode Assets Preview And it's also correct in the Xcode Assets preview: Steps to Repro In SF Symbols, create a custom symbol of "ellipsis" (right-click and Duplicate as Custom Symbol) Combine it with the "badge" component (select Custom Symbols, select the newly-created "custom.ellipsis", then right-click and Combine Symbol with Component…) Change the badge's Y Offset to 10%. Export the symbol and add it to your Xcode asset catalog. In Xcode, display the symbol inside a Button using Image(“custom.ellipsis.badge”). Add a couple more buttons separated by spacers, using system images of "ellipsis" and "app.badge". Compare the "custom.ellipsis.badge" button to the two system symbol buttons. Expected The combined symbol remains vertically centered, matching the alignment shown in both the SF Symbols export window and the Xcode asset catalog thumbnails. Actual The base symbol (e.g., the ellipsis portion) shifts vertically based on the Y offset of the badge element. This causes visual misalignment when displayed in SwiftUI toolbars or other layouts. Also included the system “envelope.badge” icon to show where a 90%, 10% badge offset should be located.

Hi everyone, I am encountering an issue where my Live Activity (Dynamic Island) suddenly became invalid and failed to launch. It was working perfectly before, and I haven't modified any code since then. My Environment: Xcode: 26.1.1 Device iOS: 26.1 Testing: I also tested on iOS 18, but the Live Activity fails to start there as well. Here is my code: Live Activity Manager (Start/Update/End): func startLiveActivity() { // Initial static data let attributes = SimpleIslandAttributes(name: "Test Order") // Initial dynamic data let initialContentState = SimpleIslandState(message: "Preparing...") // Adapting for iOS 16.2+ new API (Content) let activityContent = ActivityContent(state: initialContentState, staleDate: nil) do { let activity = try Activity.request( attributes: attributes, content: activityContent, pushType: nil // Set to nil as remote push updates are not needed ) print("Live Activity Started ID: \(activity.id)") } catch { print("Failed to start: \(error.localizedDescription)") } } // 2. Update Live Activity func updateLiveActivity() { Task { let updatedState = SimpleIslandState(message: "Delivering 🚀") let updatedContent = ActivityContent(state: updatedState, staleDate: nil) // Iterate through all active Activities and update them for activity in Activity<SimpleIslandAttributes>.activities { await activity.update(updatedContent) print("Update") } } } // 3. End Live Activity func endLiveActivity() { Task { let finalState = SimpleIslandState(message: "Delivered ✅") let finalContent = ActivityContent(state: finalState, staleDate: nil) for activity in Activity<SimpleIslandAttributes>.activities { // dismissalPolicy: .default (immediate), .after(...) (delayed), .immediate (no animation) await activity.end(finalContent, dismissalPolicy: .default) print("End") } } } The Models (Shared between App and Widget Extension): // 1. Define State (Dynamic data, changes over time, e.g., remaining delivery time) public struct SimpleIslandState: Codable, Hashable { var message: String } // 2. Define Attributes (Static data, constant after start, e.g., Order ID) public struct SimpleIslandAttributes: ActivityAttributes { public typealias ContentState = SimpleIslandState var name: String // e.g., "My Order" } The Widget Code: // // SimpleIslandWidget.swift // ReadyGo // // Created by Tang Yu on 2025/11/19. // import WidgetKit import SwiftUI import ActivityKit struct SimpleIslandWidget: Widget { var body: some WidgetConfiguration { ActivityConfiguration(for: SimpleIslandAttributes.self) { context in // UI shown on the Lock Screen VStack { Text("Lock Screen Notification: \(context.state.message)") } .activityBackgroundTint(Color.cyan) .activitySystemActionForegroundColor(Color.black) } dynamicIsland: { context in // Inside Widget Extension DynamicIsland { // Expanded Region DynamicIslandExpandedRegion(.center) { Text("Test") // Pure text only } } compactLeading: { Text("L") // Pure text only } compactTrailing: { Text("R") // Pure text only } minimal: { Text("M") // Pure text only } } } } Additional Info: This is the minimal code setup I created for testing, but even this basic version is failing. I have set NSSupportsLiveActivities (Supports Live Activities) to YES (true) in the Info.plist for both the Main App and the Widget Extension. Has anyone experienced this? Any help would be appreciated.

My project uses the UINavigationController's largeTitle on the latest iOS 26.1, but I found that when I set the backgroundColor, the navigation bar's largeTitle disappeared after switching between normal and large titles. I checked the latest documentation and consulted AI, but I have not found any good solutions. For the demo project, please refer to FB20986869

Hey there, I have an app that allows picking any folder via UIDocumentPickerViewController. Up until iOS18 users were able to pick folders from connected servers (servers connected in the Files app) as well. On iOS26, the picker allows for browsing into the connected servers, but the Select button is greyed out and does nothing when tapped. Is this a known issue? This breaks the whole premise of my file syncronization application.

Noticed when using .glassEffect within NavigationStack gives different result when interacting with view. When it is not in NavigationStack, when view pressed, glassEffect is within Capsule, clipped. But when used with NavigationStack, pressing view gives additional background effect in rectangle form. In image can see this effect, it is subtle but in other scenarios its much more visible. Is there a way how to use glassEffect without rectangle appearing in NavigationStack? Here is full code for this example. struct ExampleGlass: View { var body: some View { GlassObject() .padding() .background(.blue) } } struct ExampleGlassNavStack: View { var body: some View { NavigationStack { GlassObject() .padding() .background(.blue) } } } struct GlassObject: View { var body: some View { Capsule() .frame(height: 150) .glassEffect(.clear.interactive()) } } #Preview { ExampleGlass() ExampleGlassNavStack() }
