When running a mobile app through Xcode, why can't the associated watch app be installed within the watch app? How can this problem be solved?

When importing FoundationModels in watchOS 27 Beta 2 this error appears: /Applications/Xcode-beta.app/Contents/Developer/Platforms/WatchOS.platform/Developer/SDKs/WatchOS27.0.sdk/System/Library/Frameworks/FoundationModels.framework/Modules/FoundationModels.swiftmodule/arm64e-apple-watchos.swiftinterface:6:15 Unable to resolve module dependency: 'CoreImage' Does anybody else have this issue?

Is there a known workaround (other than forking) for watchOS builds in Xcode 27 that depend on packages without a declared watchOS 9.0 floor? I depend on several Apple SPM packages with no minimum deployment target, such as https://github.com/apple/swift-algorithms. My project's minimum is 26.0. Xcode 27 will not build watchOS targets with these packages because watchOS 8.0 is below its range of supported targets. /.../SourcePackages/checkouts/swift-algorithms/Package.swift The watchOS Simulator deployment target 'WATCHOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 27.0.x.

I’m blocked debugging a watchOS app on a physical Apple Watch. The iPhone connects to Xcode normally (wired), but the Watch either fails to connect with a tunnel timeout or disappears entirely from Xcode after I unpaired it inside Devices & Simulators. Environment Mac: macOS 26.x (Apple Silicon Mac) Xcode: 26.2 iPhone: iOS 26.1 Apple Watch Ultra: watchOS 26.2 (build 23S303) Connection: iPhone connected to Mac via USB (trusted). Watch paired to iPhone and working normally in the Watch app. Issue A (when Watch is visible in Xcode) In Xcode → Window → Devices and Simulators, the Watch shows up but is not usable and fails to connect. Error: “Previous preparation error: A connection to this device could not be established.” “Timed out while attempting to establish tunnel using negotiated network parameters.” In some attempts the Watch shows “Capacity: Unknown” / limited details, and then fails during preparation. Issue B (after unpairing Watch in Xcode only) I unpaired/removed the Watch in Xcode (Devices & Simulators). I did not unpair the Watch from the iPhone. Now: iPhone appears in Xcode and works normally for builds. Watch is still paired to the iPhone and works normally. Watch no longer appears anywhere in Xcode Devices & Simulators (no paired watch section, no watch run destination). What I’ve tried Reboots of Mac, iPhone, Watch (multiple times) Watch unlocked, awake; iPhone unlocked and close to Watch Verified Watch is paired and connected in iPhone Watch app Developer Mode enabled on iPhone and Watch Wi-Fi and Bluetooth ON (Mac/iPhone/Watch), tried toggling both Tried on home Wi-Fi and also with iPhone hotspot (same result) Resetting trust prompts / reconnecting iPhone via USB, re-trusting Mac Apple Watch: “Clear Trusted Computers” Xcode: removing/re-adding devices; clearing derived data; restarting Xcode Watch Developer networking test: Responsiveness = Medium (430 RPM) Questions 1. Is this a known issue/regression with Xcode 26.2 + watchOS 26.2 tunneling (CoreDevice / devicectl)? 2. Is there an Apple-supported way to force Xcode to re-discover a paired Watch after it was removed from Xcode Devices & Simulators (without unpairing the Watch from the iPhone)? 3. Any recommended logs or diagnostic steps I should collect (Console logs, sysdiagnose, specific Xcode/CoreDevice logs) to include in a Feedback report? If helpful, I can provide the full error text from Xcode’s Devices window and any logs you recommend. Thank you in advance,

Currently, Apple WatchOS 26 can speak "split time" in workouts, but cannot announce notifications. While iOS 26 can "Announce Notifications on Speaker" (if iPhone is locked" ), this is not available on Apple Watch Please add this feature

Does Apple WatchOS 27 support my iOS 27 app being notified when the user wakes up?

Does WatchOS 27 support an iOS 27 app making announcements on the Apple Watch?

For low vision users, can my app override the Siri-suggested 6 apps and display my suggested apps?

The process of copying shared cache symbols from my Apple Watch has been horrendous. I cannot even get past 2% complete before this process fails. Every device is on the same network. I have trusted my machine. Developer mode is enabled on the watch. I have successfully paired the phone and watch. I managed to install an Watch app onto the watch. But the shared cache symbols were never copied from the watch. I gathered several commands at the terminal to help me. rm -rf ~/Library/Developer/Xcode/DerivedData rm -rf ~/Library/Developer/CoreDevice sudo killall -9 remoted CoreDeviceService 2>/dev/null || true xcrun devicectl manage ddis update xcrun devicectl list devices Clear CoreDevice state.

We ship WidgetKit complications (StaticConfiguration, TimelineProvider) in a companion iOS + watchOS app and want to send Adobe Analytics when users add, remove, or switch complication kinds/families on their watch face. From the widget extension we only see timeline refreshes via getTimeline, which seems too noisy and unrelated to user intent to use for lifecycle tracking. On iOS we diff WidgetCenter.shared.currentConfigurations() at app launch against persisted state—is that also Apple’s recommended pattern on watchOS, or is there a supported callback we’re missing? How should this work for a companion app (watch collects and relays via WatchConnectivity vs. tracking from the iPhone Watch app) versus a standalone watch app where third-party analytics may only run on-device? We’re especially unsure how reliably removal is detected if the watch app doesn’t launch again after a complication is removed.

With the recent introduction of the unified asset pipeline and Icon Composer, managing cross-platform icon designs has become incredibly efficient. However, there is still a significant platform disparity when it comes to maintaining visual consistency and brand uniformity across paired devices. On iOS, we can dynamically change the app icon at runtime using the setAlternateIconName API. Currently, watchOS completely lacks an equivalent mechanism. If a user selects an alternative icon inside an iOS companion app, the paired Apple Watch app icon remains locked to the default primary asset. This creates a disjointed experience and directly impacts user recognition. The watchOS home screen relies entirely on instant visual cues. If a user changes their iPhone icon to a custom colorway, they instinctively look for that same colorway on their wrist. Leaving the watch icon unchanged makes it harder to quickly locate the app. I have submitted an enhancement request via Feedback Assistant to bring alternate app icon support to watchOS, ideally through an automatic system-level sync within the unified .icon pipeline, or via a native watchOS runtime API. If your app utilizes alternate icons and you would like to see this cross-device continuity brought to watchOS, please consider filing your own duplicate request to help bring visibility to this gap.

What are the best practices for a painless physical watchOS debugging loop in Xcode? Debugging a standalone or companion watchOS app on a physical Apple Watch is arguably the slowest feedback loop in Apple development. Every minor code change often results in Xcode getting stuck on "Installing to Apple Watch" for minutes, or throwing a "Failed to attach" LLDB error after a long timeout. The biggest bottlenecks seem to be: The initial Symbol Copying / dyld shared cache sync: This takes forever whenever watchOS gets updated. Can these symbols be pre-cached or manually downloaded on the Mac via an internet connection rather than pulling them byte-by-byte from the watch? Slow Installation over Bluetooth: The watch often defaults to a sluggish Bluetooth link with the iPhone instead of leveraging local Wi-Fi or the direct Mac-to-Watch network tunnel. Debugger Connection Timeouts: Xcode routinely loses track of the target process before the app finishes launching on the watch. My Question: What are your recommended workflows, hidden Xcode flags, build settings, or networking setups to make physical watchOS debugging as close to the simulator experience as possible? Specifically, how do we handle symbol caching and force faster deployment pipelines?

I'm making an apple watch game and it's running so smooth and nice while developing but I ran into a showstopping problem that I wouldn't even have noticed until i deleted the app and reinstalled... Every first-run on a freshly installed copy of the game has major frame hitches as it loads assets. Every run after that has ZERO hitches and runs like butter. Even if i install a new version on top of the old one (which is why i never noticed this problem in my almost finished game) it runs smooth. Framerate issues come back if I delete and reinstall. I think it's compiling shaders or caching geometry but I haven't been able to trick it into doing the hard work during non-critical moments in the game. I've tried preloading assets in the main menu, loading at the start of the level, loading and rendering in a tiny part of the screen, rendering behind dialog boxes... it seems no matter what i can only get rid of the frame hitches after the game has been played through once... and I'm going to lose all customers on that first terrible impression even though the game is actually really good and fun when it's running properly... Any suggestions how i can prewarm/precompile the assets to avoid framerate hitches and freezes during gameplay? I thought I was so close to release but I feel this is un-shippable! I can send a link to my test flight build to anyone that wants to see the problem first hand. Also please note that I am artist-forward with a technical lean, but certainly not a real programmer, unfortunately. Jiovanie

Anyone know how to get watchOS to update on a reluctant iPhone/watch combo?

Xcode 27 refuses to build common Swift Packages for watchOS, such as swift-algorithms or swift-collections. ... 'WATCHOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 27.0.x. The error disappears by explicitly declaring in the SPM manifest "platforms: [.watchOS(.v9)]". (Patching the "SwiftStdlib" availabilities in swift-collections is insufficient.) Is there a better workaround than mirroring our whole SPM graph to declare the platform minimum? Our projects' minimums are correctly set at 11 or 26. (Also happens in the hello world Xcode 27 watchOS only project.) FB23037701 ref: https://developer.apple.com/forums/thread/829540

Environment: MacBook Air M4 macOS 27 Golden Gate Beta Xcode 27 Beta iPhone running iOS 27 Beta Apple Watch Series 10 paired to the iPhone Steps to Reproduce: Install macOS 27 Beta and Xcode 27 Beta. Pair an Apple Watch with an iPhone running iOS 27 Beta. Enable Developer Mode on the iPhone. Connect the iPhone to the Mac and launch Xcode. Open Window → Devices and Simulators. Attempt to locate the paired Apple Watch or enable Developer Mode on the watch. Expected Result: The paired Apple Watch appears in Xcode for development purposes. A Developer Mode option is available on the Apple Watch. Xcode is able to recognize and communicate with the watch through the paired iPhone. Actual Result: The Apple Watch does not appear in Xcode. No Developer Mode option is visible on the watch. The iPhone is successfully paired and running iOS 27 Beta, but the watch remains unavailable for development workflows. Additional Notes: The iPhone and Apple Watch are already paired and functioning normally. Developer Mode is enabled on the iPhone. Restarting devices and reconnecting the iPhone did not resolve the issue. Unsure whether this is a limitation of the current beta builds or a regression in Xcode/watchOS development tooling.

In the last few weeks 5 users have reported my workout watch app being unable to read health data despite the permissions being enabled in the iPhone Settings app. This has been a common complaint over the years and is usually fixed by disabling the permissions; rebooting both devices; and then enabling them again. This usually nudges iOS into sending the permissions to watchOS. However that procedure doesn't work for these users, all of whom are using watchOS 10.6.2. They are using various versions of iOS 18 or 26 so it seems to be a problem with that version of watchOS, which users are usually limited to because their hardware won't support anything more up to date. It seems that unpairing and re-pairing the watch can fix the problem but not always. I looked around and it seems that other apps are having the same problem: https://www.reddit.com/r/runna/comments/1rhhs2n/runna_wont_start_an_outdoor_run_on_apple_watch/ Does anyone know a way to fix this? My current advice is to repeatedly unpair / re-pair until it works, which isn't really practical! Thanks in advance.

I would like to create an Apple Watch only app that queries data such as blood oxygenation, heart varibility, number of steps, energy consumed, and other data of a similar nature recorded over the past month and performs calculations on them. I read from the HealthKit documentation that Apple Watch synchronizes data with iPhone and periodically deletes older data, and that I can get the date from which the data is available with earliestPermittedSampleDate(). Is there a risk that in general, by making queries to retrieve data up to a month old, the data will no longer be available? I need the app to work properly without needing an iPhone.

I have a app that has both mobile and watch versions. Recently some testers report that the watch app could not be launched if the put the app in the background and then resume. And if they kill the app and try to launch again, there is no any response when tapping the app icon. I managed to export some system logs by installing a sysdiagnose profile, and this info looks suspicious

I was having some trouble installing app to test on my Apple Watch (Series 9) so I removed it and thought to re-add it. However, after removing it, it no longer shows under my iPhone for me to add it as a possible run destination. I have tried numerous actions: Restart all devices Repair my watch Use hotspot so everything is on the same network Delete and reinstall Xcode None of these actions seem to be working. Does anyone have a way to get my watch to show up?
