I'm reporting a critical Health data synchronization failure that began immediately after updating from watchOS 18 to watchOS 26.0.2 (stable release) and persists in watchOS 26.1 beta 2. Bug Description: Complete failure of Health data sync from Apple Watch to iPhone Health app. All health metrics are being captured and stored locally on the watch but fail to sync to the paired iPhone. Affected Data Types: Activity rings (Move, Exercise, Stand) Heart rate measurements Sleep tracking data Workout data All other HealthKit data points Environment: Device: Apple Watch Series 7 Initial failure: watchOS 26.0.2 (23R362) - stable release Current: watchOS 26.1 beta 2 (23S5052c) Paired iPhone: iPhone 17 Pro Max, iOS 26.1 beta 2 (23B5052c) Bluetooth and Wi-Fi connectivity: Normal Watch pairing status: Connected and functional for all other features Reproduction: Updated Apple Watch Series 7 from watchOS 18 to watchOS 26.0.2 on September 30, 2025 Health data sync ceased completely starting October 1, 2025 Issue persists after updating to watchOS 26.1 beta 2 and iOS 26.1 beta 2 Data remains stored locally on watch and is viewable in watch apps Apple Watch appears as connected data source in Health app but no data transfers Troubleshooting Performed: Multiple device restarts (both iPhone and Apple Watch) Bluetooth/Wi-Fi toggling and reconnection Verified Privacy > Motion & Fitness > Fitness Tracking and Health enabled on both devices Confirmed data source priority settings in Health app Extended charging periods to allow background sync operations Verified no Low Power Mode restrictions Impact: Critical functionality loss for primary Apple Watch use case. Unable to track longitudinal health data, breaking continuity of health records dating back to watchOS 18. Feedback Submitted: FB20533870 filed via Feedback Assistant with sysdiagnose from both devices Questions for Engineering: Is this a known regression in watchOS 26.0.2 or later builds? Are there any watchOS 26.1 beta release notes addressing HealthKit sync issues that I should review? Should I capture additional diagnostic data (e.g., specific console logs, HealthKit database states)? Is unpairing/re-pairing expected to resolve this, or would that indicate a deeper architectural issue? Additional Context: Apple Watch appears in Settings > Bluetooth as connected Can successfully change watch faces from iPhone Notifications, Messages, and calls work normally No previous sync issues prior to watchOS 26.0.2 Senior Apple Support advisor escalation completed; awaiting engineering review This appears to be a regression introduced in watchOS 26.0.2. Any guidance on additional diagnostics or confirmation of a fix in upcoming builds would be appreciated.

Looking at the UIDesignRequiresCompatibility documentation, watchOS is not listed among the supported platforms. When added to the project, it is also being ignored, resulting in Liquid Glass design. It is possible to opt-out from Liquid Glass design temporarily. Is that just an oversight for Apple Watch please?

Hello, My watchOS app has been performing fine by requesting background app refresh and then requesting any new data from health kit in the background so that the widget can be updated. However, on watchos26 I have been unable to read data in the background, with any query returning zero results. That same data is clearly read just fine while in the foreground. Can anyone assist?

Hi, I'm developing a watchOS app, no parent iOS app, when I archive the app, and submit it to APP Store Connect, it returns an info.plist error that I didn't set micphone permission description, but I actually set it. Could anyone how to fix it? and how to submit only a watchOS APP? Any help will be appreciated! thanks！

I'm having problems with my released app with iOS & WatchOS 26 support. I've added AppIntentConfiguration support in the WatchOS app such that users can configure the complication. My complications also support multiple families and so I have slightly different configuration options available if its in the .accessoryRectangular slot or the .accessoryCircular one. This works fine on Apple Watch when editing the Watch face. Here you can then select the configuration options fine and they are correct for the different variants. However on iOS when configuring in the Apple Watch app on iPhone, the different complication size is ignored and the same configuration options are offered meaning they are wrong for one of them. I created a sample project, here is the app intent code: struct TestWidgetConfigurationIntent: AppIntent, WidgetConfigurationIntent { static var title: LocalizedStringResource = "New Widgets with Configuration" static var description = IntentDescription("Lots of stuff.") static var isDiscoverable: Bool { return false} init() {} func perform() async throws -> some IntentResult { return .result() } @Parameter(title: "Enable More Detail", default: true) var moreDetail: Bool @Parameter(title: "Enable Other Parameter", default: true) var otherParameter: Bool static var parameterSummary: some ParameterSummary { When(widgetFamily: .equalTo, .accessoryRectangular) { Summary("Test Info") { \.$moreDetail \.$otherParameter } } otherwise : { Summary("Test Info") { \.$moreDetail } } } } In WatchOS you get the correct configuration options: In iOS you do not, you get the same configuration option regardless of which family size you select: This could be a bug so I've filed feedback FB20328319. Otherwise if anyone has insights, it would be very appreciated. This is all tested on the current iOS 26.0 and WatchOS 26.0 versions. Thanks!

I'm developing a watchOS companion app for my iOS app in Xcode 26.0.1 on macOS Sequoia. The watch app uses a simple ObservableObject class with @Published properties for state management, which compiles fine for iOS but fails for the watchOS target. Error: Initializer 'init(wrappedValue:)' is not available due to missing import of defining module 'Combine' Code: swiftimport SwiftUI import WatchConnectivity import Combine // Added explicitly class WatchConnectivityProvider: NSObject, ObservableObject { @Published var distance: Double = 0 @Published var isActive: Bool = false // Additional @Published properties... } Environment: Xcode 26.0.1 (17A400) macOS Sequoia watchOS deployment target: 11.0 Apple Watch Series 11 running watchOS 11.6.1 What I've tried: Adding import Combine explicitly Cleaning build folder Verifying target membership This same code pattern works in the iOS target Is @Published / Combine supported differently in watchOS under Xcode 26? This code worked in previous Xcode versions. What's the recommended approach for observable state in watchOS apps with Xcode 26?

Are there any HealthKit related changes to be aware of in the new update that enables SPO2 / Blood Oxygen Saturation measurements on certain Apple Watch models within the US? I’m aware of processing happening on the phone…. But beyond that: Does this mean values are then saved to Apple Health? Do these models still take background SPO2 measurements in the same way as other models do? Are these values then visible in third party iOS apps as normal through HealthKit? Do these values sync back to the paired Apple Watch HealthKit store for third party apps to access on the Watch? For reference I have an iOS and WatchOS app that, amongst other features, provides the ability to see your SPO2 values in the Watch app, complications and in the iOS app.

Notification coordination between iOS and watchOS is not working properly watchOS and iOS try to coordinate between phone and watch notifications. The concept here is that if there is a main app and a companion app, they could both be sending a notification, then the notification would alert on both, which is a deviation from how notification mirroring is handled if there is an iOS app but no watch app. The watch waits for the iOS notification to fire so they can determine if this is the same notification that needs to be deduped, displayed on one device but not the other, or separate notifications to be displayed both. If there is no notification on the phone, the watch will timeout after 13 seconds and alert anyway. If you have an iOS companion app, the best solution to this is to send the same notification on both devices simultaneously, and ensuring the UNNotificationRequest.identifier matches on both notifications. This will let the systems determine how to handle the notification correctly and quickly, and the notification will alert right away. https://developer.apple.com/forums/thread/765669 According to the above article, "when a notification arrives on watchOS alone first, it coordinates with iOS," but in reality, it doesn't work properly. Detailed process of this phenomenon watchOS receives a notification. On watchOS, the notification is not immediately shown to the user. iOS receives a notification with the same UNNotificationRequest.identifier as in (1). The notification in (3) does not appear on either iOS or watchOS. However, the notification from (3) does appear in iOS Notification Center. Thirteen seconds after watchOS received the notification, the notification from (1) is shown to the user on watchOS. In the end, the iOS and watchOS notifications are not consolidated and each remains in its respective notification center. Up to (3) there are no issues. Starting with (4), both iOS and watchOS exhibit a lot of odd behavior. This phenomenon occurs with both local notifications and push notifications. When iOS receives the notification first, there is no problem. The notification for watch received later is processed appropriately, and the watchOS notification is not additionally displayed to the user. Expected proper process Same as above. Same as above. Same as above. The notification in (1) is integrated into the notification in (3). The notification in (3) is alerted to the user immediately. 2 sample projects to reproduce Only the main code is attached. Sample project1: local notifications Swift code for local notification app (iOS, watchOS) - App.swift.txt Sample project2: push notifications This sample project is implemented using Firebase Functions and Firebase Cloud Messaging. Swift code push notification app (iOS, watchOS) - App.swift.txt Server side JavaScript code for FirebaseFunction - index.js.txt Tested devices and OS This phenomenon occurred in both of the following patterns. Pattern 1 Xcode 26.0 iPhone 16 (iOS 26.0) Apple Watch series 10 (watchOS 26.0) Pattern 2 Xcode 16.4 iPhone 11 (iOS 18.6) Apple Watch SE 2nd gen (watchOS 11.6) Question Is this phenomenon a bug? Or is my understanding or implementation incorrect? Feedback Assistant number FB20339772

Hello, I’ve run into an issue with a configuration profile on my supervised iPhone. I’m wondering if anyone here might be able to help? The profile contains the allowListedAppBundleIDs key within the restrictions payload. My Apple Watch is paired with the iPhone. The iPhone was supervised manually with Apple Configurator, hence the Apple Watch has not been directly supervised itself. The profile works completely as expected when installed on the phone. As soon as the profile is installed on the iPhone, I can witness the apps on the Apple Watch rearrange themselves as some apps are hidden. So clearly the profile is applying its restrictions to the Apple Watch to some degree. My issue however is that apps listed in the whitelist are hidden from the Watch. The apps that are missing from my Watch are Walkie Talkie, Find My Items, Find My Friends, Messages, Alarm, Remote, Now Playing, Sleep, Meditation and Heart Rate. This is despite the following bundle IDs being listed in the whitelist array: com.apple.findmy.findpeople, com.apple.findmy.finddevices, com.apple.HeartRate, com.apple.SessionTrackerApp, com.apple.NanoWorldClock, com.apple.findmy.finditems, com.apple.Mind, com.apple.NanoOxygenSaturation, com.apple.watchmemojieditor com.apple.NanoSleep com.apple.NanoNowPlaying com.apple.noise com.apple.tincan com.apple.NanoRemote com.apple.NanoAlarm com.apple.private.NanoTimer com.apple.NanoStopwatch I’ve done some testing, but not sure what I’ve found really. I’ve so far identified 3 scenarios. Scenario 1: I have the whitelist profile installed on the iPhone. I download an app that appears in the whitelist from my watch (or at least its iPhone version does). The apps show up on the iPhone automatically and can be launched there. These apps cannot be launched on the watch. Scenario 2: I downloaded a few apps to my watch, that didn’t automatically install on my iPhone at the same time. They were on the whitelist. These ones couldn’t be launched from my Watch. I then downloaded them to the iPhone and they could be launched there (since they were on the whitelist). Scenario 3: A couple of 3rd party apps on the whitelist could be downloaded and launched from the watch with the whitelist installed. It seems as though there are different kinds of Apple Watch app and this is what I’ve read elsewhere. First of all there are Watch-only apps, which do not automatically install a companion iPhone app. Secondly there are companion apps, which when installed from the Watch App Store download their companion app to the iPhone in the background. Someone please correct me - I’m bound to be overlooking something here. So maybe the apps that when installed from Watch automatically install on iPhone and can only be launched from the iPhone have a separate bundle ID for their Watch app which I haven’t included? Apps that are on the whitelist AND do not automatically install an iPhone app AND can be launched from the Watch, include: solstice What3words So maybe these do not need a companion app, but have the same Bundle ID as their iPhone app? However, I’m still not sure why many stock Apple Watch apps are missing from the Watch…. The most obvious answer is that I’ve got their Bundle IDs wrong, but I don’t think I have given I extracted the bundle IDs from the App Store pages of the Apple WatchOS apps. I noticed at this Apple Support page (https://support.apple.com/en-gb/guide/deployment/dep34c5cd30f/1/web/1.0) that there is no mention of whitelisting or blacklisting apps on WatchOS using MDM, yet something definitely happens on the watch when the configuration profile is installed on the iPhone. Furthermore, if I tap on a configuration profile, which comprises a blacklist, on my iPhone it will ask me if I want to install it on the iPhone or Watch. The same pop-up question doesn’t happen when the profile contains a whitelist. All this to say, I’m massively confused as to why I can’t get this working. I’d really appreciate anyone’s advice which is bound to be expert. Thank you

I added a watchkit extension to an existing app. I get this error when uploading to App Store Connect. Building the archive itself is fine: Prepared archive for uploading Upload failed error: Validation failed Missing Info.plist value. A value for the key “WKApplication”, or “WKWatchKitApp” if your project has a WatchKit App Extension target, is required in “Runner.app/Watch/watch_Watch_App.app” bundle. For details, see: https://developer.apple.com/documentation/watchkit/creating_independent_watchos_apps/setting_up_a_watchos_project have the exact same issue when bundling. I added the flag manually in a additional plist fields entry with WKApplication=1 because my Info.Plist is generated and it didn't help. I wrote a custom Run Script Phase that added the flag and that didn't help as well. I need a reply from someone from Apple here. This needs to be fixed.

Hi everyone, I’m building a sports performance app for Apple Watch that uses the onboard IMU to analyze swings and impacts in sports like tennis and golf. The goal is to estimate club/racket head speed, ball speed, and shot quality in real time from wrist motion data. With Core Motion, I can currently get deviceMotion updates at ~100 Hz. While this is fine for general movement tracking, the actual ball impact happens much faster — 5–10 ms in tennis and ~0.5 ms in golf. Many of the high-frequency vibration/impact components are missed at 100 Hz, making it hard to directly measure or more accurately estimate certain performance metrics. Questions for Apple / community: 1. Is there a way to access raw accelerometer and gyroscope data at higher sampling rates (e.g., 500–1000 Hz) on Apple Watch? 2. If not, is this due to hardware limitations or an API/software constraint? 3. Are there any research, partner, or beta programs that allow deeper sensor access for sports-science use cases? Even modest increases in IMU sampling could unlock more accurate ball-speed estimates, impact force analysis, and strike-quality detection without needing external sensors — making Apple Watch a best-in-class wearable for precision sports analytics. Happy to share more about the current approach, sample data, and potential use cases if helpful. Thanks, Max

I struggling in getting Xcode Cloud to work with a stand alone watch app. This app has the following three targets and each bundle identifier is set up in the Identifiers section of the developer portal. iphone container target called Unleashed abc.xyz.Unleashed watch target called Unleashed Watch App abc.xyz.Unleashed.watchkitapp watch target called Unleashed WidgetExtension abc.xyz.Unleashed.watchkitapp.Unleashed-Widget I have a App Store provisioning set up for abc.xyz.Unleashed.watchkitapp The app runs fine in the watch simulator, but fails with the following when I do an Xcode Cloud build Export archive for ad-hoc distribution Export archive for development distribution Export archive for app-store distribution When I expand each one of these errors it reports: Command exited with non-zero exit-code: 70 I also tried archiving the project in Xcode then selected the Archive but it won't let me validate because that button is disabled. Very confused I have successfully used Xcode Cloud for a phone app but am having a problem with this watch app that has a widget

Our app has an infrequently used but useful calculator screen similar to Apple's calculator app where the current value ticker squats in the top toolbar trailing area, extending into the system clock area. In 26 beta, that view is now broken: the system clock not longer hides when a layout collision is detected. Can the prior avoidance behavior (or an API to hide the clock) be triggered somehow?

I'm trying to update the icon of my app for watchOS 26, and I'm having troubles providing both a layered Liquid Glass icon for watchOS 26 users and a pre-rendered bitmap icon (in various sizes) for watchOS 11 and older users. Whatever I do; I either get a blurry, scaled-down watchOS 26 icon on watchOS 11; or watchOS 11's bitmap icons on watchOS 26. While I could get the wanted result on macOS 26 and iOS 26, I simply can't get an equivalent result with watchOS 26.

Hello everyone! I encountered a problem, Apple Watch 10, downloaded beta version 26 IOS, got tired of it, deleted in the settings to the previous IOS. As a result, now I deleted 26 IOS on the phone and can not connect the watch with the phone.

I’m developing a smart alarm app that makes use of the extended runtime session. I’ve looked at the docs, and one of the background modes for Apple watch is smart alarm. The docs also say that an extended runtime session can only be scheduled one at a time, and while the app is open, which isn’t very intuitive for an alarm app that runs on schedules. I’ve seen other apps do something similar, but I’m trying to make this fully automated, without the user having to do too much manually to reschedule the smart alarm. Is there no way to do this? I would’ve thought the smart alarm background modes would allow to schedule more than 1/a repeating extended runtime session.

I updated my IntentWidgetProvider recommendations() to return an empty array instead of all my previous static IntentRecommendation to allow my widgets to finally be configurable. When I go to the watch widget chooser I see samples of my widgets OK: But when I touch the sample would should bring up my configurations, I get "Unable to Load": Anybody see this or have any ideas? Thanks.

Hello developers, Now I'm facing a issue with a image alingment on watchOS app. As you see below, I load a UIImage on a view of watchOS app using SwiftUI and would like to fill the watch screen fully with the image. (That's why I added '.ignoreSafeAre()' modifier) As expected, the image fills the screen but the image is aligned to the left only in case of a landscape image (width > height). I tried anything I imagine, but all failed. Can anybody give a hint or advice to solve this issue? Many thanks in advance! ZStack{ Image(uiImage: image) .resizable() .aspectRatio(contentMode: .fill) .ignoresSafeArea() .scaleEffect(zoom) .offset(...) .gesture(... }

I'm trying to figure out how to make an inverted list in my watchOS app for a message view, so that messages appear from the bottom first, and go up. Everything I've tried so far has some sort of major drawback, and I'm wondering if there's some proper way to do it. My current implementation is flipping every message item upside-down, then flipping the whole list upside-down. This works in making the list go from bottom to top, but the digital crown scroll direction is also inverted. Simply inverting the array of messages doesn't work either, as the user has to scroll to the bottom of the list manually every time. Any tips/suggestions would be greatly appreciated.
