When using Section(_:isExpanded:) inside a List with .listStyle(.sidebar) in a NavigationSplitView, some rows don't animate with the others during collapse and expand. Specific rows (often in the middle of the section) snap in/out instantly while the rest animate smoothly. I've reproduced this with both static views and ForEach. Minimal reproduction: struct SidebarView: View { @State private var sectionExpanded = true @State private var selection: Int? var body: some View { NavigationSplitView { List(selection: $selection) { Section(Section, isExpanded: $sectionExpanded) { ForEach(1...3, id: .self) { index in NavigationLink(value: index) { Label(Item (index), systemImage: (index).circle) } } } } .listStyle(.sidebar) .navigationTitle(Sidebar) } detail: { if let selection { Text(Selected item (selection)) } else { Text(Select an item) } } } } Environment: macOS 26.3, Xcode 26.3, SwiftUI Steps to reproduce: Run the above code in a macOS app Click the section disclosure chevron to collapse Observe that s

Hello, I have a critical issue regarding the Family Controls (Distribution) entitlement. My app FocusPact was approved for the entitlement, but there is a technical mismatch in the Bundle IDs that prevents distribution via TestFlight. [Current Situation] Parent App ID: com.hayashikento.FocusPact (Approved / Capitalized) Approved Extension ID: com.hayashikento.focuspact.ShieldConfigurationExtension (Approved / Lowercase) [The Issue] Due to the case-sensitivity difference (FocusPact vs focuspact), Xcode throws a Bundle identifier prefix mismatch error. Since the parent app identifier is already established as capitalized, I cannot change it to lowercase without breaking the existing configuration. [Request] I have submitted a new entitlement request with the corrected capitalized Bundle ID: Corrected Extension ID: com.hayashikento.FocusPact.ShieldConfigurationExtension Could a DTS engineer please help me synchronize the approved status to this capitalized ID? This is purely a technical correction of an

I am developing a Flutter iOS application and encountering a crash when using biometric authentication (Face ID) via the local_auth plugin. ■ Environment Flutter: 3.x local_auth: 2.2.0 (also tested with 2.1.6) iOS: real device (Face ID is working normally for device unlock) Firebase Authentication (email/password) Xcode build ■ Issue When calling biometric authentication, the app crashes immediately. Code: final didAuthenticate = await auth.authenticate( localizedReason: 'Authenticate to login', options: const AuthenticationOptions( biometricOnly: false, useErrorDialogs: false, ), ); ■ Error Thread 1: signal SIGABRT Crash occurs in libsystem_kernel.dylib (__pthread_kill) Happens immediately when authenticate() is called No exception is caught in Dart (native crash) ■ Verified NSFaceIDUsageDescription is correctly included in Info.plist Confirmed it exists in the built Runner.app Info.plist localizedReason is non-empty and in English Flutter clean / pod install executed App reinstall

Hi everyone, I’m seeing a strange rendering issue in Xcode 26.3 that seems to affect only the iOS Simulator. Environment: Xcode 26.3 SwiftUI app Reproduces in Simulator only Reproduces across multiple simulator device models My code is just a minimal example Expected behavior: The view should fill the entire screen. Actual behavior: The app content is rendered only inside a centered rounded rectangle/card-like area, with black space around it, as if the app canvas is being clipped incorrectly. Minimal reproduction: import SwiftUI @main struct LayoutShowcaseApp: App { var body: some Scene { WindowGroup { Color.green.ignoresSafeArea() } } } I also tried wrapping it in a ZStack and using: .frame(maxWidth: .infinity, maxHeight: .infinity) .background(...) .ignoresSafeArea() but the result is the same. What I already tried: Clean Build Folder Switching simulator device models Resetting simulator content/settings Rebuilding from a fresh minimal SwiftUI project Since this happens with such a minima

I’m seeing what looks like a compiler / macro-expansion / build-pipeline issue. Environment: Xcode 26.4 RC (17E192, latest); I believe it is also reproducible on earlier versions. github source code I reduced this to a very small macOS/iOS app plus a local macro package. The app logic is trivial, but app exits immediately on launch with code 138 Important observations: If I inline everything into a single file, the problem disappears. I also see an error like this during investigation: The file path does not exist on the file system: /var/folders/.../swift-generated-sources/@__swiftmacro_18MacroFeedbackRepro20MountActivationState17PreservedRawValuefMm_.swift That makes me suspect this is not an application logic issue, but something in macro expansion / generated source handling / compiler pipeline.

I’m seeing a visual glitch with toolbar buttons when building with Xcode 26 for iOS 26. During transitions (both pushing in a NavigationStack and presenting a .sheet with its own NavigationStack), the toolbar button briefly flashes the wrong background colour (black in dark mode, white in light mode) before animating to the correct Liquid Glass appearance. This happens even in a minimal example and only seems to affect system toolbar buttons. A custom view with .glassEffect() doesn’t have the issue. I’ve tried: .tint(...), UINavigationBarAppearance/UIToolbarAppearance, and setting backgrounds on hosting/nav/window but none of those made any difference. Here’s a minimal reproducible example: import SwiftUI struct ContentView: View { @State private var showingSheet = false var body: some View { NavigationStack { List { NavigationLink(Push (same stack — morphs)) { DetailView() } Button(Sheet (separate stack — flashes)) { showingSheet = true } } .navigationTitle(Root) .scrollContentBackground(.hidden) .b

Since 26.4 beta 3 I've been having errors after a few hours of using Claude Agent. I get an error stating that I am not authed. If I go into Xcode settings, it still shows I am signed into Claude Agent. I have click sign out and then go through the whole auth process again to start using the agent again. This is on two separate computers. Is there anything I can do to stop this behaviour and stay logged in for longer? It worked fine in 26.3.

Just installed the new Xcode 26.4 RC build (17E192) after happily using 26.3 for a few months. I'm noticing some immediate regressions in the Intelligence features: Frequent losing of OAuth token (Claude Agent). This had previously been fixed and now is back. Agent Thinking is constrained to thought bubble windows, which are (a) too small to read, (b) not scrollable when thinking goes beyond a few paragraphs. Yes they are tappable when thinking is finished, but this doesn't help. Due to (2), in deep thinking, it's impossible to follow progress beyond the visible window, so impossible to know if the agent is going off the rails. I'm noticing just more general slowness to complete tasks. Not just complete them -- it seems like it takes longer to START tasks, which is really weird. It sits there thinking for longer. Same project, same model as before. Every time you tap New Chat it presents both Claude and Codex choices, even if you're only signed into one. This turned a simple single tap into now a req
