I'm working with the Apple Watch's acceleration data and have referred to the document Identify the coordinate axes of the device. According to this document, the X-axis points to the right side of the watch, the Y-axis points towards the top side, and the Z-axis points towards the user. However, when I place the watch on a flat surface and move it horizontally to the right, I observe that the X-axis acceleration is negative. Similarly, when I move the watch vertically upwards, the Y-axis acceleration also shows a negative value. Is this expected behavior, or am I misunderstanding something about the coordinate system or acceleration readings?

Just triple-checking if it's only my Apple Watch Series 8 where the weather widget in the notification area is only showing 'WNW.' I think it's supposed to be showing the weekdays or the temperature.

Whenever I try to build on my Apple Watch using Xcode, I often encounter connection issues. It typically takes about an hour of troubleshooting, including restarting devices, restarting Xcode, erasing the Apple Watch, and other steps. I was wondering if anyone else has experienced similar problems and if there are any effective solutions.

We have a watchOS app in TestFlight that is currently crashing on any device running watchOS 11 and up. I have an older Apple Watch SE that's capped at 10.6.1 that can run the app just fine, but the same exact install on a newer device fails. This started happening after I updated my MacBook to macOS Sequoia and Xcode to 16. In order to get the Watch app to run on the 10.6.1 device, I had to change the Swift Optimization Level from -O to -Osize. I already filed Feedback on this (FB15691116). I've tried so many different things and have come up with nothing to show for it. When I look in the IPS file, I see that the crash point in my code on the watchOS 11 device is at KinesiaUOnWatch`@objc SessionDelegator.session(_:activationDidCompleteWith:error:): 0x3a3f48 <+0>: sub sp, sp, #0x60 0x3a3f4c <+4>: stp x26, x25, [sp, #0x10] 0x3a3f50 <+8>: stp x24, x23, [sp, #0x20] 0x3a3f54 <+12>: stp x22, x21, [sp, #0x30] 0x3a3f58 <+16>: stp x20, x19, [sp, #0x40] 0x3a3f5c <+20>: stp x29, x30, [sp, #0x50] 0x3a3f60 <+24>: add x29, sp, #0x50 0x3a3f64 <+28>: mov x19, x4 0x3a3f68 <+32>: mov x23, x2 0x3a3f6c <+36>: mov x22, x0 0x3a3f70 <+40>: mov w0, #0x0 ; =0 0x3a3f74 <+44>: bl 0x89818 ; symbol stub for: type metadata accessor for Swift.MainActor 0x3a3f78 <+48>: mov x24, x0 0x3a3f7c <+52>: adrp x25, 161 0x3a3f80 <+56>: ldr w25, [x25, #0x654] 0x3a3f84 <+60>: mov x20, x0 0x3a3f88 <+64>: bl 0x8980c ; symbol stub for: static Swift.MainActor.shared.getter : Swift.MainActor 0x3a3f8c <+68>: mov x21, x0 0x3a3f90 <+72>: adrp x0, 166 0x3a3f94 <+76>: add x0, x0, #0xc40 ; lazy protocol witness table cache variable for type Swift.MainActor and conformance Swift.MainActor : Swift.Actor in Swift Incident Identifier: 08E2F667-7965-4C86-B85E-9E2F03EAA963 Beta Identifier: AD390666-55CB-43B3-9B14-BD3E70F456EB Hardware Model: Watch6,1 Process: KinesiaUOnWatch [389] Path: /private/var/containers/Bundle/Application/B571E983-F2B0-40EF-9F0D-8C471CAEB3FB/KinesiaUOnWatch.app/KinesiaUOnWatch Identifier: com.glneurotech.kinesiau.watchapp Version: 5.1.0 (510271) AppStoreTools: 16B39 AppVariant: 1:Watch6,1:11 Beta: YES Code Type: ARM64_32 (Native) Role: Foreground Parent Process: launchd [1] Coalition: com.glneurotech.kinesiau.watchapp [464] Date/Time: 2024-12-03 15:12:51.1876 -0500 Launch Time: 2024-12-03 15:12:50.0000 -0500 OS Version: Watch OS 11.1 (22R585) Release Type: User Report Version: 104 Exception Type: EXC_BREAKPOINT (SIGTRAP) Exception Codes: 0x0000000000000001, 0x000000002053dd4c Termination Reason: SIGNAL 5 Trace/BPT trap: 5 Terminating Process: exc handler [389] But, as I said, this exact app runs just fine on an older watchOS 10.6.1 device.

Hi. I’m not sure where to post it, but after 1.5 years with the AWU2 the main Watch face is still bugged, missing seconds (two digit) in format. In the attached example it shows “06:30:5” for 10 seconds until it hits ”06:31:00”. I’m not sure if it’s only related to Danish AWU’s. But it is so annoying, and has forced me to change watch to Garmin in the past. PLEASE FIX IT, please please.

Hello, since the last version of iOS and WatchOS I have a problem with this code. This is the minimal version of the code, it have two pickers inside a view of a WatchOS App. The problem its with the focus, I can't change the focus from the first picker to the second one. As I said before, it was working perfectly in WatchOS 10.0 but in 11 the problems started. struct ParentView: View { @FocusState private var focusedField: String? var body: some View { VStack { ChildView1(focusedField: $focusedField) ChildView2(focusedField: $focusedField) } } } struct ChildView1: View { @FocusState.Binding var focusedField: String? @State private var selectedValue: Int = 0 var body: some View { Picker("First Picker", selection: $selectedValue) { ForEach(0..<5) { index in Text("Option \(index)").tag("child\(index)") } }.pickerStyle(WheelPickerStyle()).focused($focusedField, equals: "first") } } struct ChildView2: View { @FocusState.Binding var focusedField: String? @State private var selectedValue: Int = 0 var body: some View { Picker("Second Picker", selection: $selectedValue) { ForEach(0..<5) { index in Text("Option \(index)").tag("childTwo\(index)") } }.pickerStyle(WheelPickerStyle()).focused($focusedField, equals: "second") } } When you do vertical scrolling on the second picker, the focus should be on it, but it dosnt anything. I try even do manually, setting the focusState to the second one, but it sets itself to nil. I hope that you can help me, thanks!

I have released a watchOS-specific application that retrieves data from the iPhone calendar app and displays it on the Apple Watch. It uses the calendars function in EKEventStore to retrieve the list of calendars, but it seems that it sometimes fails to retrieve iCloud calendars. Trouble is, this problem only occurs in a very few users‘ environments, the majority of other users’ environments are able to retrieve them without any problems, and I cannot reproduce it at all in my environment. Local calendars and Google calendars seem to be retrieved without any problems. Minimal example code: import SwiftUI import EventKit struct ContentView: View { let eventStore = EKEventStore() @State var success: Bool = false @State var calendarNames: [String] = [String]() func request() async { success = (try? await eventStore.requestFullAccessToEvents()) ?? false } func list() { calendarNames = eventStore.calendars(for: .event).map { $0.title } } var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Access: \(success.description)") ScrollView { ForEach(calendarNames, id: \.self) { name in Text(name) } } } .onAppear { Task { await request() list() } } .padding() } } I asked the user experiencing the problem to try restarting the iPhone and Apple Watch, reinstalling the app and re-pairing them, but there was no change. I would appreciate any information you can provide. Best regards.

It may have made sense in the early days of watchOS, but given the Apple Watch is now 10 years old and we have "Standalone" Apple Watch apps, it no longer makes sense to have this seemingly arbitrary limitation of only being able to query 7 days of data on the watch. I have an open feedback (FB7649612) from 2020 with no responses and ask this question every year at WWDC Developer labs. WHY must we still deal with this limitation which only causes other developers to store critical health data in iCloud or on their own servers in order to provide a robust stand alone watch experience on the Apple Watch. Even Apple themselves must either use a separate private API or use iCloud for the new Vitals app. How else can I escalate this request?

First post here! Is there a way to reduce the number of haptic feedback for double tap on primary button? Context: Double tap is awesome. Two haptic actuations are given to the gesture to let the user know that the gesture is "received" then a third haptic feedback is given shortly after to signal the primary button is tapped. Is there a way to disable the third haptic feedback. In other words make primary action "silent"? I have tested a number of apps that supports double tap, it seems to me that the triple tap is a system level default, and it cannot be changed. Any help would be greatly appreciated.

Exploring Live Activity feature for Apple Watch right now and found that it has this default view with "Open on iPhone" button when you tap Live Activity. That button perfectly brings iOS app to foreground as if you tapped iOS's Live Activity. Is there a way to mimic that behavior from inside Watch app code? From inside WKApplicationDelegate, for example Tried openSystemURL but it seems lile it's only available for tel or sms links

I'm unable to pair my Apple Watch Ultra (watch os 11.1 GA) onto Ios 18.2 beta 2 (had same issue with beta 1). I get a Phone out of date Error and was wondering if someone had a workaround. I tried backing up my phone, restoring on a 18.1 GA phone and tried to pair there (in hopes of later restoring backup on 18.2 b2) but I got the same error on 18.1 after the restore; I'm guessing somewhere in the backup it incorrectly restores the iOS version. I am able to pair watch on a non restored 18.1. HELP!

Our company has developed a product available, which measures body composition. During the measurement process, lasting 40 seconds, we require the device screen to remain illuminated. We are actively using the "Always On" feature and have set the timer on the watch to 70 minutes to prevent the screen from dimming. However, we are encountering issues where the screen may still turn off during the measurement. Could you please provide guidance on how to keep the screen active with backlighting across all Apple Watch models during measurements?

Apple Watch doesn't vibrate for notifications version: 11.1 help please

Hi, We have a bank app which can activate tokenized payment cards (in Requires Activation status) on Apple devices. In my case some customers tried to activate their card token on their Apple Watch. Our card system gathered all the required card data with the PNO and sent them to our app. Our app called the PKPassLibrary.activate() method, but got back the Swedish localizedDescription "Oväntat fel" which means "Unexpected error" in English. We checked our card system logs and contacted our PNO, both found no issue and no explanation to the unexpected error. How can we identify the issue here? Can we somehow find a more detailed error log from Apple Server? Best regards, Adrian Lui

I got a new MacBook and set it up as a new one, not transferring any data from the old one. But now the Apple Watch (Series 6) paired with my iPhone (14 Pro Max) ist not shown in Xcode. iPhone and Watch are using the latest RC and also Xcode is the latest RC. But in Xcode I ca only see my iPhone, not the paired Watch. See Screenshots. The first shows the new MacBook and the second the old one. I already tried a lot, but nothing helps: Unpair Watch from Phone and then pair it again Plug the iPhone to different USB ports Restart Watch, iPhone and Mac Delete the iPhone from Xcode Enable and disable Developer Mode on iPhone and Watch What else can I try to get the Watch back?

Dear all, i am a music conductor and developer, and to fulfill my joy with music i recently developed a WatchFace and some apps for a non-apple watch called "PineTime". My whole development is done in c++ and is available at https://github.com/luto65/PineConductor/ Since I am aswell an apple developer, and most of my friends have apple watches, i am now porting those c++ apps to the apple watch. I just finished the very first one, that is actually a watch Face I now ported it to appleWatch and it looks pretty similar too (here a screenshot from the simulator) I would like to now remove the annoying digital hour on the top right corner, and then sell it as new custom face, together with my other swift-ports of my original c++ applications. Looking forward any feedback.

Even after resetting my watch 3x and doing a hard reset I keep getting the notification “Your iPhone has a policy that requires a new Apple Watch password” I have tried and tried to re-set it only to keep getting the same notification

The peripheral is initiating a passkey entry mechanism, IOS device is getting a pop up to enter the passkey but the WatchOS device is not displaying any pop-up. Is there anything to be enabled from the watch side?

Can someone confirm this is supposed to be happening after all these years. I have noticed that now when I delete the messages from my Apple Watch (IOS11) they are now deleting from my phone (IOS18). I was glad I noticed and was able to recover them but I almost lost some impoRyan messages. I did do a test and confirm this is true. But the question is, is this supposed to be happening and if so is there a way to disable only this sync? I like to try and keep the messages icon on the watch clean since when I read the messag on my phone it does sync read on the watch and leaves the unread number on the icon.

There's no option to help me turn it on in my iPhone 16 Pro Max MYW43LL/A (iOS 18.1 developer beta) and Apple Watch Series 10 MWX13LW/A (watchOS 11 Developer Beta).
