Target: WatchOS 10.5 NOTE: This is a watchOS only app Given: A single view containing NavigationSplitview, with the List in the "sidebar", a TabView in the "detail" and a TabView in a sheet attached to each tab in the "detail" view. When: Navigating between top-level list and "detail" TabView, or navigating through "detail" to "sheet" TabView Then: Memory leaks occur. If the TabView() views are replaced with List() views there are no longer memory leaks. There are no reference types involved. Everything is in Structs Code below causes the issue which can be observed in Instruments. So my question is what have I coded incorrectly to cause this issue? Or, How can I fix this? Thanks in advance. @main struct VerticalTabView_MemLeak: App { var body: some Scene { WindowGroup { ContentView() } } } struct ContentView: View { struct ParentItem: Identifiable, Hashable { var id = UUID() var name: String var children: [Item] init(_ name: String, _ children: [Item]){ self.name = name self.children = children } } struct Item: Identifiable, Hashable { var id: UUID = UUID() var name: String init(_ name: String){ self.name = name } } @State var selectedParentItem: ParentItem? @State var selectedItem: Item? var parentItems = [ ParentItem("A", [Item("one"),Item("two"),Item("three")]), ParentItem("B", [Item("four"),Item("five"),Item("six")]), ParentItem("C", [Item("seven"),Item("eight"),Item("nine")]) ] var body: some View { NavigationSplitView { List(selection: $selectedParentItem) { ForEach(parentItems, id: \.id) { parentItem in NavigationLink(value: parentItem) { HStack { Text(parentItem.name) } .padding() } } } .navigationTitle("Top Level") } detail: { if let items = selectedParentItem?.children { TabView(selection: $selectedItem) { ForEach(items, id:\.id) { item in Text(verbatim: item.name) .tag(item) .onTapGesture { selectedItem = item } } } .tabViewStyle(.verticalPage) .navigationTitle(selectedParentItem?.name ?? "") .sheet(item: $selectedItem, onDismiss: { selectedItem = nil }, content: { item in TabView { Text(item.name).foregroundStyle(.yellow) Text(item.name).foregroundStyle(.yellow) } .tabViewStyle(.verticalPage) .navigationTitle(selectedParentItem?.name ?? "") }) } } } } #Preview { ContentView() }

Starting from Xcode 16 Beta 2, NSValue.CGSizeValue is no longer available on watchOS, whereas this method was supported in previous versions of Xcode. The Xcode header files mark this method as unavailable on watchOS, but after manually modifying the Xcode files to remove the unavailable macro, the code compiles and runs normally. Is there a change in this API that makes it unsupported on watchOS, or is this an error? Previously, I submitted feedback FB14072192, and the status of this feedback was updated to "Unable to diagnose with current information" without any further response. If this is indeed an issue, I hope it can be fixed.

Hi, Suddenly product's are not being loaded on WatchOS anymore, no error throwing. Just empty array response... Works normal on iOS. Any idea why? WatchOS 10.5

During WatchOS 10 dev betas and now into 11 dev betas, I am still seeing were stands are not being detected. What I do not know is if the steps are detected. But here is the situation. Today: I was going on some wiring outside and in the basement. I was clearly up and moving around for over an hour. I can see on my camera's I went outside at 15:50, came back in at 16:18. Then went to my basement and was working down there from 16:19 until 16:30. After that cleaned up my mess. So I was up and down stairs and without a doubt standing. At 16:50 I got the reminder to stand. Other cases: 1: I get home from work about XX:10 . I have to walk about 50 ft from my garage to my house, up stairs, take the dog out, make dinner, and finally get my chair to eat and at XX:50 I get the reminder. 2: I'm at work, I'm going to get lunch and I have to walk pretty far and again at XX:50 I get the reminder. This is very rare, but it has happened. Now, in a odd twist. I get up in the morning at XX:50, I have 10 steps to the bathroom, and I manage to get that hourly stand.

I have a watchOS app written in C++, Swift and SwiftUI. This app is meant only for 64-bit architecture. I know Apple uses the arm architecture, so I thought arm64 will be the arch of latest AppleWatches. I tested my code in x64 simulator (Intel Mac) and arm64 simulator (silicon Mac) - no trouble. Next is to test on a device - AppleWatch Series 9, model: A2984. I set the arch to arm64 and my application failed to build, with Xcode showing a popup about arch mismatch... which is due to the app's arch begin different from device's arch. When I change Xcode arch setting to arm64_32, then I don't get this popup, but my builds fail. When I read about arm64_32, I realised that this is a version of arm64 with 32 bit pointers... not the arm64 with 64 bit pointers. Looking at the specification of AppleWatch Series 9, Apple has confirmed that it has 64 bit CPU, but the instruction set is unknown. This wiki page about different AppleWatch CPUs is marked TBC for AppleWatch Series 9. From Xcode, I got to know that this unconfirmed arch is arm64_32. This completely breaks my code. Are there any 64-bit watches with 64-bit pointer sizes? What is Apple's future in this area? Do they plan to release AppleWatches that support 64-bit pointers or it's always going to be 32?

I am developing a watchOS-only app, and whenever I attempt to make a network request, it always fails and throws the following error: Error Domain=NSURLErrorDomain Code=-1009 "The Internet connection appears to be offline." I noticed that when I turn off Wi-Fi and Bluetooth in the settings of the iPhone paired with the Apple Watch (thus disconnecting the Apple Watch from the iPhone), my app can successfully connect to the network. Additionally, when the app contains both an iOS app and a watchOS app, after granting network permissions on the iOS app, the watchOS app can access the network normally when connected to the iPhone. When opening some system apps on the Apple Watch (such as the "Workout" app), the app will display a network permission request similar to that on iOS, but this request does not automatically pop up when my watchOS app attempts to access the network. Is there a way to request network permissions in a watchOS-only app so that it can access the network while connected to the iPhone?

Hello, I am developing an application for the Apple Watch that requires the screen to remain active even when the wrist is moved into a down position. The core functionality of my app involves providing continuous visual and auditory guidance, and it's critical that the screen stays on without going into power-saving mode while the app is in use. Specifically, I am looking for a way to: 1.Disable the screen's power-saving mode when the wrist is moved down. 2.Ensure the screen remains active as long as the app is in the foreground. I understand that certain power management features are built into watchOS for battery conservation, but I would need this behavior to be overridden only while the application is running (the app would not be in the foreground for extended periods of time). Is there an approved method or best practice within Apple's guidelines to achieve either of these functionalities? Thank you for your assistance.

I have installed IOS18 and WatchOS11 Beta 3 already... all complications sent to clock (usign FACER app) is not showing up... they all appears DISABLED. doesnt matter what face watch i use.., its all disabled. Any help on it please????

I have a watchOS app where a user can select a picture. I’d like the picture to be displayed in a complication. I’m using WidgetKit, and I found out that for some watch faces (rendering mode = accented), the image gets tinted. Instead of the picture, the user sees only a colored box. It appears that using the old framework, ClockKit, it was possible to display an image that gets slightly colored with the tint color on tinted watch faces. I believe this is to ensure backward compatibility of old complications. My question is: can I do the same using WidgetKit? I tried using the widgetAccentable() modifier, but it doesn’t work. Here's an example of what I mean. In the middle complication, instead of the pink square, I'd like to display the user picture.

Looking into making requests using URLSession via a proxy, on watchOS, and found that in URLSessionConfiguration, there's a proxyConfigurations property. However, since ProxyConfiguration is part of the Network framework, does it means that TN3135 low level networking rules also applies in this case?

Hello, I have an iOS app and a companion watchOS app. Users record a workout on Apple Watch, the data for which is then transferred using both Watch Connectivity and Core Data + CloudKit (NSPersistentCloudKitContainer) to their iPhone, where it is processed and displayed. As users are recording the workout on their Apple Watch, when they finish and the transfer begins, their iPhone is often not reachable to immediately send the data using Watch Connectivity and they have no network connection (cellular or Wi-Fi). With Watch Connectivity I use transferFile from WCSession, which queues the file for transfer. With Core Data + Cloudkit I save the data and the export is queued. An undetermined amount of time may pass until the user returns to their iPhone or connects to Wi-Fi and most of the time neither of the transfer methods actually transfers the data until the user opens the watchOS app into the foreground, at which point the transfer happens immediately for both methods. I've tried a number of things already, without success, such as: Using sendMessage from WCSession to send an immediate message to the watchOS app when the iOS app returns to the foreground to try and wake the watchOS app up so it can complete the data transfer. On the watchOS app, after attempting to transfer the data, using downloadTask from URLSession to queue a background task to download something, in the hope that it would wake the watchOS app when network connectivity was restored and enable it to complete the data transfer. On the watchOS app, instead of saving the data using NSPersistentCloudKitContainer, using CKRecord and CKDatabase directly to save the data using userInitiated as the quality of service, in the hope that it would be exported once network connectivity was restored. Is there a way to trigger the watchOS app to transfer the data using Watch Connectivity or Core Data + CloudKit in the background when reachabillity or network connectivity is restored, even if the app may have been suspended by watchOS? Many Thanks, Alex

import AVFoundation Button { let utterance = AVSpeechUtterance(string: "Hello world") utterance.voice = AVSpeechSynthesisVoice(language: "en-GB") utterance.rate = 1 let synthesizer = AVSpeechSynthesizer() synthesizer.speak(utterance) } label: { Text("hello") } i omitted some code but this is the core part. When i run this on apple watch se 2 simulator (watch os 10.5) nothing happens and gives the error Query for com.apple.MobileAsset.VoiceServicesVocalizerVoice failed: 2 Unable to list voice folder Query for com.apple.MobileAsset.VoiceServices.GryphonVoice failed: 2 Unable to list voice folder Query for com.apple.MobileAsset.VoiceServices.CustomVoice failed: 2 Unable to list voice folder Query for com.apple.MobileAsset.VoiceServices.GryphonVoice failed: 2 Unable to list voice folder

I'm not quite sure whether this post belongs in a Design forum or here, but with iOS 18 Developer Beta 1 and watchOS 11 Developer Beta 1, when a Live Activity is displayed on an Apple Watch, the system font used is SF Pro rather than SF Compact. I would expect that the design guidance would be to stick with SF Compact while on watchOS, and I would expect that the system font, when displayed on the Apple Watch using .supplementalActivityFamilies([.small]), would appear as SF Compact. To ensure that SF Compact appears on my Live Activity when viewed on Apple Watch, I can set a custom font for use with the small supplemental family, but this seems really clunky; is there any other guidance here?

I'm excited to bring my Live Activity to Apple Watch via the .supplementalActivityFamilies([.small]) modifier. However, I'm also wondering whether it is possible for my watchOS app, separately, to initiate a Live Activity and receive updates for it via push notification. From my testing it seems like no, but the function call itself can be made, since ActivityKit is available on watchOS. Are there any other recommendations for how to go about initiating a Live Activity from a watchOS app? Would I have to communicate with a companion iOS app to start the Live Activity on the phone instead?

When I initiate WKExtendedRuntimeSession with a background mode of "Underwater Depth" I get an orange indicator showing the Action button on the screen that stays showing all the time and then animates when you press the action button. I believe this started with a recent WatchOS update, because it never happened before. Does anyone know how to hide it? Or keep it and be able to detect the Action button presses within my app (if possible)?

When I start a workout in my app, the system shows a Live Activity in the Smart Stack like in the picture. My app opens if I tap on it, but the pause and resume buttons doesn't do anything. I have implemented the PauseWorkoutIntent and ResumeWorkoutIntent which works with the Action Button. I guessed that these would be used from this Live Activity as well, but it seems like not. Has anyone successfully integrated with this? I haven't seen it documented anywhere, although I think it was already included in watchOS 10. This is also shown when using the built in workout app and for that the buttons work as expected.

I have started to work on adding Live Activities to my app in watchOS 11. The app already has interactive Live Activities on the phone that works as expected. I have added a view for the activityFamily: small and it shows up as expected. My problem is that buttons doesn't work. I use the Intent based button, and on the iPhone Lock Screen they work. On the watch, nothing happens. Has anyone got this working? Not sure if I'm missing something or if it's a bug.

I've been seeing warning like the following with my Apple Watch app: === AttributeGraph: cycle detected through attribute 140952 === === AttributeGraph: cycle detected through attribute 131640 === === AttributeGraph: cycle detected through attribute 131640 === === AttributeGraph: cycle detected through attribute 131640 === === AttributeGraph: cycle detected through attribute 131640 === === AttributeGraph: cycle detected through attribute 131640 === === AttributeGraph: cycle detected through attribute 131640 === I've done some debugging with Instruments and Xcode, I've determined that its caused by adding a .toolbar { ToolbarItemGroup(placement: .topBarTrailing) { Label("Stop", systemImage: "xmark") } } to an item within my NavigationSplitView List Destination view. To aid reproduction of this issue even more, I've verified the same warning occurs with the Apple sample code from the WWDC23 Backyard Birds app. https://developer.apple.com/documentation/swiftui/backyard-birds-sample?changes=_9 If you take the Apple sample code, open it in Xcode 15.4 and run it in the Apple Watch WatchOS 10.5 simulator, then select the Bird Springs item, all is well. If you then add the above toolbar code to the BackyardSummaryTab file at the bottom of the VStack, you'll see the same AttributeGraph issues I'm seeing in my app. Is this a bug? I can't understand why adding a static ToolBarItem in WatchOS is causing this. I've seen this issue in the simulator and also on device.
