Zoom navigation transitions for tabViewBottomAccessory are not working in SwiftUI with ObservableObject or Observable
The zoom navigation transition with matchedTransitionSource in tabViewBottomAccessory does not work when a Published var in an ObservableObjector Observable gets changed. Here is an minimal reproducible example with ObservableObject: import SwiftUI import Combine private final class ViewModel: ObservableObject { @Published var isPresented = false } struct ContentView: View { @Namespace private var namespace @StateObject private var viewModel = ViewModel() // @State private var isPresented = false var body: some View { TabView { Button { viewModel.isPresented = true } label: { Text("Start") } .tabItem { Image(systemName: "house") Text("Home") } Text("Search") .tabItem { Image(systemName: "magnifyingglass") Text("Search") } Text("Profile") .tabItem { Image(systemName: "person") Text("Profile") } } .sheet(isPresented: $viewModel.isPresented) { Text("Sheet") .presentationDragIndicator(.visible) .navigationTransition(.zoom(sourceID: "tabViewBottomAccessoryTransition", in: namespace)) } .tabViewBottomAccessory { Button { viewModel.isPresented = true } label: { Text("BottomAccessory") } .matchedTransitionSource(id: "tabViewBottomAccessoryTransition", in: namespace) } } } However, when using only a State property everything works: import SwiftUI import Combine private final class ViewModel: ObservableObject { @Published var isPresented = false } struct ContentView: View { @Namespace private var namespace // @StateObject private var viewModel = ViewModel() @State private var isPresented = false var body: some View { TabView { Button { isPresented = true } label: { Text("Start") } .tabItem { Image(systemName: "house") Text("Home") } Text("Search") .tabItem { Image(systemName: "magnifyingglass") Text("Search") } Text("Profile") .tabItem { Image(systemName: "person") Text("Profile") } } .sheet(isPresented: $isPresented) { Text("Sheet") .presentationDragIndicator(.visible) .navigationTransition(.zoom(sourceID: "tabViewBottomAccessoryTransition", in: namespace)) } .tabViewBottomAccessory { Button { isPresented = true } label: { Text("BottomAccessory") } .matchedTransitionSource(id: "tabViewBottomAccessoryTransition", in: namespace) } } }

Degraded RoomPlan performance
We have been using RoomPlan in our app for 2+ years. Through a combination of in-app and manual coaching on scanning best practices, most users are able to achieve high-quality scans on a consistent basis. In recent weeks, however, we have observed an increase in reports of degraded scanning performance, even from veteran users who had not previously encountered issues. The RoomCaptureView overlay is jittery and crooked, and the resulting scan file has significant issues, even for simple, well-lit rectangular rooms. It is difficult to troubleshoot these issues given the number of variables at play, and the overall volume of reports is still relatively low, but we'd appreciate any guidance on known issues or workarounds that could help unblock our users who are being affected by this. I noticed that this post includes an acknowledgement of FB14454922 and FB15035788. Our issues seem slightly different as the scans are simply inaccurate and jittery without failing outright. I haven't found any other threads on similar issues.

Incorrect menu consistency warnings logged in Tahoe for NSStatusItem, performance issues related?
Is anyone else getting new warning about menu items with submenus when running on Tahoe? I'm getting big performance problems using my menu as well as seeing these messages and I'm wondering if there's a connection. My app is faceless with a NSStatusItem with an NSMenu. Specifically it's my own subclass of NSMenu where I have a lot of code to manage the menu's dynamic behavior. This code is directly in the menu subclass instead of in a controller because the app I forked had it this way, a little wacky but I don't see it being a problem. A nib defines the contents of the menu, and it's instantiated manually with code like: var nibObjects: NSArray? = [] guard let nib = NSNib(nibNamed: "AppMenu", bundle: nil) else { ... } guard nib.instantiate(withOwner: owner, topLevelObjects: &nibObjects) else { ... } guard let menu = nibObjects?.compactMap({ $0 as? Self }).first else { ... } Within that nib.instantiate call I see a warning logged that seems new to Tahoe, before the menu's awakeFromNib is called, that says (edited): Internal inconsistency in menus - menu <NSMenu: 0x6000034e5340> believes it has <My_StatusItem_App.AppMenu: 0x7f9570c1a440> as a supermenu, but the supermenu does not seem to have any item with that submenu My_StatusItem_App.AppMenu: 0x7f9570c1a440 is my menu belonging to the NSStatusItem, NSMenu: 0x6000034e5340 is the submenu of one of its menu items. At a breakpoint in the NSMenu subclass's awakeFromNib I print self and see clear evidence of the warning's incorrectness. Below is a snippet of the console including the full warning, only edited for clarity and brevity. It shows on line 32 menu item with placeholder title "prototype batch item" that indeed has that submenu. Internal inconsistency in menus - menu <NSMenu: 0x6000034e5340> Title: Supermenu: 0x7f9570c1a440 (My StatusItem App), autoenable: YES Previous menu: 0x0 (None) Next menu: 0x0 (None) Items: ( "<NSMenuItem: 0x6000010e4fa0 Do The Thing Again, ke mask='<none>'>", "<NSMenuItem: 0x6000010e5040 Customize\U2026, ke mask='<none>'>", "<NSMenuItem: 0x6000010e50e0, ke mask='<none>'>" ) believes it has <My_StatusItem_App.AppMenu: 0x7f9570c1a440> Title: My StatusItem App Supermenu: 0x0 (None), autoenable: YES Previous menu: 0x0 (None) Next menu: 0x0 (None) Items: ( ) as a supermenu, but the supermenu does not seem to have any item with that submenu (lldb) po self <My_StatusItem_App.AppMenu: 0x7f9570c1a440> Title: My StatusItem App Supermenu: 0x0 (None), autoenable: YES Previous menu: 0x0 (None) Next menu: 0x0 (None) Items: ( "<NSMenuItem: 0x6000010fd7c0 About My StatusItem App\U2026, ke mask='<none>', action: showAbout:, action image: info.circle>", "<NSMenuItem: 0x6000010fd860 Show Onboarding Window\U2026, ke mask='Shift', action: showIntro:>", "<NSMenuItem: 0x6000010fd900 Update Available\U2026, ke mask='<none>', action: installUpdate:, standard image: icloud.and.arrow.down, hidden>", "<NSMenuItem: 0x6000010e46e0, ke mask='<none>'>", "<NSMenuItem: 0x6000010e4780 Start The Thing, ke mask='<none>', action: startTheThing:>", "<NSMenuItem: 0x6000010e4dc0 \U2318-\U232b key detector item, ke mask='<none>', view: <My_StatusItem_App.KeyDetectorView: 0x7f9570c1a010>>", "<NSMenuItem: 0x6000010e4e60, ke mask='<none>'>", "<NSMenuItem: 0x6000010e4f00 saved batches heading item, ke mask='<none>', view: <NSView: 0x7f9570b4be10>, hidden>", "<My_StatusItem_App.BatchMenuItem: 0x6000016e02c0 prototype batch item, ke mask='<none>', action: replaySavedBatch:, submenu: 0x6000034e5340 ()>", "<NSMenuItem: 0x6000010f7d40, ke mask='<none>'>", "<My_StatusItem_App.ClipMenuItem: 0x7f956ef14fd0 prototype copy clip item, ke mask='<none>', action: copyClip:>", "<NSMenuItem: 0x6000010fa620 Settings\U2026, ke='Command-,', action: showSettings:>", "<NSMenuItem: 0x6000010fa6c0, ke mask='<none>'>", "<NSMenuItem: 0x6000010fa760 Quit My StatusItem App, ke='Command-Q', action: quit:>" ) Is this seemingly incorrect inconsistency message harmless? Am I only grasping at straws to think it has some connection to the performance issues with this menu?

Why MapKit Is So Unpredictable for macOS?
I have an existing iOS app with MapKit. It always shows the current user location with UserAnnotation. But the same isn't true for macOS. I have this sample macOS application in SwiftUI. In the following, the current user location with a large blue dot appears only occasionally. It won't, 19 of 20 times. Why is that? I do have a location privacy key in Info.plist. And the Location checkbox is on under Signing & Capabilities. import SwiftUI import MapKit struct ContentView: View { @State private var markerItems: [MarkerItem] = [ MarkerItem(name: "Farmers Market 1", lat: 35.681, lon: 139.691), MarkerItem(name: "Farmers Market 2", lat: 35.685, lon: 139.695), MarkerItem(name: "Farmers Market 3", lat: 35.689, lon: 139.699) ] @State private var position: MapCameraPosition = .automatic var body: some View { Map(position: $position) { UserAnnotation() ForEach(markerItems, id: \.self) { item in Marker(item.name, coordinate: CLLocationCoordinate2D(latitude: item.lat, longitude: item.lon)) } } .mapControlVisibility(.hidden) .mapStyle(.standard(elevation: .realistic)) .ignoresSafeArea() } } #Preview { ContentView() } struct MarkerItem: Hashable { let name: String let lat: Double let lon: Double }

Getting crashes when using QLPreviewPanel on AddressBook items
My app (FindAnyFile) provides a Finder-like interface in which it also offers a QuickLook preview command, which invokes [[QLPreviewPanel sharedPreviewPanel] makeKeyAndOrderFront:nil]; Now, if it shows .abcdp files, it often, but not always, crashes. This has been happening for many macOS versions, at least since 10.15, up to 26.1. Also, it does not seem to matter which SDK/Xcode I build with, as I used several and all versions lead to the crash. The issue rather appears to be inside the QLplugin for the AB file (ABCardCollectionView etc.). I am able to trace this crash in Xcode. There are a LOT of errors and warnings coming up, and eventually the qlplugin throws an ObjC exception which in turn brings down my entire app (and here I thought that the XPC system was designed to expressly avoid such crashes). Possibly significant errors are: CNAccountCollectionUpdateWatcher 0x6000025cf800: Update event received, but store registration failed. This event will be handled, but the behavior is undefined. Error using remote object proxy when fetchAnonymousXPCEndpoint: Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.telephonyutilities.callservicesdaemon.callstatecontroller" UserInfo={NSDebugDescription=connection to service named com.apple.telephonyutilities.callservicesdaemon.callstatecontroller} connection to service named com.apple.coreduetd.people … CNPropertyNotFetchedException: A property was not requested when contact was fetched. I've attached the (mostly) complete console output from such a debug run. I have also an open bug report regarding this kind of crash (back then I was not able to reproduce it myself): FB15553847 Also, when I "Quick Look" the same file in Finder, I get a "Preview not permitted" for the same items that crash in my app. If I copy the same items to the Desktop, then Finder can QL them and my app doesn't crash when viewing the item on the Desktop. So, the crash only happens with the items inside ~/Library/Application Support/AddressBook/Sources/…/Metadata/. Now, here is the weirdest part: You might think: So, if the Finder shows "Preview not permitted", then my app trying to view those items is the result of that condition (even if that's not supposed to crash). However: I have a clean 26.1 install (in an Apple ARM VM) where Finder also says "Preview not permitted" for these items in the user's Library/AB/Metadata folder, but my app can QL those items without crashing! Also, I have one user who uses 26.1 and gets the crash with files in the same location. So, the "Preview not permitted" is probably not the cause of this crash, though it's suspicious that a user gets this at all - why can't a user QL the abcdp files in the Metadata folder but when copied to the Desktop, QL works? You'd think that Finder has the necessary entitlements to access the AB, or doesn't it? Of course, my app has permission enabled under Privacy & Security / Contacts (if it's disabled, then the app can't show anything but will also not crash). And it has the "Address Book" entitlement. Would be nice if this could be looked into and eventually be fixed. Alternatively, I'd welcome any suggestions on how to prevent my app from crashing if the qlplugin throws. But if you look at the stack trace you'll see that there's no method of my own app involved where I could insert an exception catcher. I added code to my previewItemURL delegate method to make sure the NSURL item is readable, and it is, even Of course, apart from the issue with .abcdp files, the QL operation in my app works flawlessly, i.e. I have never received any other crash reports relating to any other QL plugins.

URL.startAccessingSecurityScopedResource() returns false for "On My iPad" after a while
My app allows to save user-selected URLs in a list and browse them with a tap. A user reported that the app often shows that when browsing their saved entry for "On My iPad", it's apparently empty (it contains no files). I saved "On My iPad" in my own list some time ago and noticed that the same issue occurs. The URL seems to be correctly resolved from the saved bookmark data, but I noticed that url.startAccessingSecurityScopedResource() returns false. The other URL I saved some time ago is iCloud Drive, which I can access without issues. If I select "On My iPad" again in a file importer, create new bookmark data from it and resolve the URL from it, access works correctly. I create bookmark data like this: let data = try url.bookmarkData(includingResourceValuesForKeys: [.localizedNameKey, .pathKey, .volumeIsLocalKey]) and resolve URLs like this: let url = try URL(resolvingBookmarkData: data, bookmarkDataIsStale: &bookmarkDataIsStale) bookmarkDataIsStale is false for both the working and not working URLs for "On My iPad". The two bookmark data are different though, even if url.path is the same. What could be the issue?

Internal Tester not getting update
Have had issues all day with the delayed Processing times as seen by other posts on this forum. But after my app has completed Processing (took 4 hours, usually takes 10 minutes), the build doesn't show up for Internal Tester. Internal tester usually gets all app updates, but when I try to add Group to build, the internal tester group is greyed out. If I try to add individual tester to build I get "An error has occurred. Try again later."

Xcode Suddenly Failing to Build for ARM64 Simulator on Apple Silicon (M1)
Hi all, I’m suddenly experiencing an old issue again and can no longer build my project to run on the local iOS simulator. I’m using a MacBook with an M1 (ARM64) processor and Xcode for development. Until recently, everything was working as expected. However, when I opened Xcode today, I noticed new build options such as ARM64 and ARM64 + x86_64, and I’m also seeing simulator entries running under Rosetta. I don’t recall seeing these options the last time I used Xcode. At the moment: Building for “Any iOS Device (arm64)” succeeds. Building for Rosetta-based simulators also succeeds (which I understand are intended for Intel-based processes). However, when I select an ARM64 simulator, the build fails with the error: “Framework Podd_App not found.” It appears that simulator builds targeting ARM64 are being restricted or misconfigured, possibly due to a corrupted setting or a recent update. Has anyone experienced this before, or can suggest which settings I should check to resolve this issue? Thanks in advance.

BLE audio packet loss on iPhone 17 (Bluetooth 6 / N1) in real-time streaming
Hello Apple Bluetooth team, We are developing a real-time call translation system that streams raw PCM audio over BLE between iPhone and custom earbuds. This works reliably on iPhone 14 / 15 / 16, but on iPhone 17 (Bluetooth 6, N1 chip) we see severe and repeatable BLE packet loss, affecting both microphone uplink and TTS downlink. Our audio stream 16 kHz, 16-bit mono PCM 20 ms frames (~640 bytes) continuous bidirectional BLE streaming What happens on iPhone 17 BLE packets are frequently dropped entire audio frames are missing results in ASR gaps and broken TTS playback occurs even with strong RSSI and no RF interference Same firmware, same BLE protocol, same MTU and connection interval work normally on older iPhones. Questions We would like to know: Did Bluetooth 6 / N1 change BLE throughput, buffering, or scheduling? Are there new limits on sustained notify / write-without-response traffic? Is BLE audio now arbitrated differently against Wi-Fi / A2DP on iPhone 17? Is BLE still expected to support low-latency continuous audio streaming on iPhone 17, or is this no longer a safe assumption? Any guidance or new best practices would be greatly appreciated. Best regards, Valenti Zhang

Can't download files from file provider's folder if they are read-only
I face this issue only on macOS 26 and only on the Intel architecture. I'm unable to download files from a file provider's folder when I make them read-only. STEPS TO REPRODUCE Download the sample from https://developer.apple.com/documentation/fileprovider/synchronizing-files-using-file-provider-extensions?language=objc Follow the steps on the page to configure the project. Build the project. Run it. Add a domain. Open the domain's folder in the Finder. Move a file to the domain's folder. Right-click on the file in the domain's folder and select "Remove Download". Close the Finder's window with the domain's folder and kill all the "Provider" processes to get rid of running instances of the extension. Change Item's capabilities in Item.swift to make the items read-only: var result: NSFileProviderItemCapabilities = [ .allowsContentEnumerating, .allowsReading ] Rebuild the project and run it. Open the domain's folder and try to drag and drop the file from the extension's folder to, let's say, the Desktop folder. EXPECTED RESULT The file is copied ACTUAL RESULT A dialog pops up with text "The file “filename” cannot be downloaded. Do you want to skip it?" Stop/Skip

“Keep Going with Apps” Tutorial section will not complete.

AppKit - Legal to Change a View's Frame in -viewDidLayout?
I have (had) a view controller that does a bit of manual layout in a -viewDidLayout override. This was pretty easy to manage - however since introducing NSGlassEffectView into the view hierarchy I sometimes am getting hit with "Unable to simultaneously satisfy constraints" and Appkit would break a constraint to 'recover.' It appears translatesAutoresizingMaskIntoConstraints is creating some really weird fixed width and height constraints. Here I wasn't doing any autolayout - just add the glass view and set its frame in -viewDidLayout. At runtime since I do manual layout in -viewDidLayout the frames are fixed and there is no real "error" in my app in practice though I wanted to get rid of the constraint breaking warning being logged because I know Autolayout can be aggressive about 'correctness' who knows if they decide to throw and not catch in the future. In my perfect world I would probably just prefer a view.doesManualLayout = YES here - the subviews are big containers no labels so localization is not an issue for me. Rather than playing with autoresizing masks to get better translated constraints I decided to set translatesAutoresizingMaskIntoConstraints to NO and make the constraints myself. Now I get hit with the following exception: "The window has been marked as needing another Layout Window pass, but it has already had more Layout Window passes than there are views in the window" So this happens because the view which now has constraints -- I adjusted the frame of it one point in -viewDidLayout. My question is - is not legal to make changes in -viewDidLayout - which seems like the AppKit version of -viewDidLayoutSubviews. In UIKit I always thought it was fine to make changes in -viewDidLayoutSubviews to frames - even if constraints were used - this is a place where you could override things in complex layouts that cannot be easily described in constraints. But in AppKit if you touch certain frames in -viewDidLayout it can now cause this exception (also related: https://developer.apple.com/forums/thread/806471) I will change the constant of one of the constraints to account for the 1 point adjustment but my question still stands - is it not legal to touch frames in -viewDidLayout when autolayout constraints are used on that subview? It is (or at least was if I remember correctly) permitted to change the layout in -viewDidLayoutSubviews in UIKit but AppKit seems to be more aggressive in its checking for layout correctness). What about calling -sizeToFit on a control in viewDidLayout or some method that has side effect of invalidating layout in a non obvious way, is doing things like this now 'dangerous?' Shouldn't AppKit just block the layout from being invalidated from within -viewDidLayout - and leave whatever the layout is as is when viewDidLayout returns (thus making -viewDidLayout a useful place to override layout in the rare cases where you need a sledgehammer?)

How to detect when Apple Watch is removed from wrist during active workout session?
I'm currently collecting real-time heart rate data using HKWorkoutSession. I want to track when the Apple Watch is physically removed from the user's wrist during an active workout. However, I've noticed that workoutBuilder(_:didCollectDataOf:) continues to be called even after the watch is removed from the wrist. Is there a way to detect when the Apple Watch is removed from the wrist during an active HKWorkoutSession? Or is this tracking not possible through the HealthKit framework? Any guidance or alternative approaches would be appreciated.
