Dear All, I am developing a watchOS app for Apple Watch Ultra that needs to use the Apple depth / water submersion APIs with the entitlement. The app is configured with the shallow depth and pressure entitlement right now, and I have verified that the entitlement is present both in the signed Watch app and in the embedded provisioning profile. App configuration: Platform: watchOS Device: Apple Watch Ultra Entitlement used: com.apple.developer.submerged-shallow-depth-and-pressure = true Info.plist contains: WKSupportsAutomaticDepthLaunch = true WKBackgroundModes includes underwater-depth I verified the built Watch app with: codesign -d --entitlements :- /path/to/WatchApp.app The output contains: com.apple.developer.submerged-shallow-depth-and-pressure I also verified the embedded provisioning profile with: security cms -D -i /path/to/WatchApp.app/embedded.mobileprovision The embedded profile also contains: com.apple.developer.submerged-shallow-depth-and-pressure The built Watch app Info.plist also confirms: WKSupportsAutomaticDepthLaunch = true WKBackgroundModes includes underwater-depth At runtime, my diagnostics show: Requested source: Automatic or Apple Sensor Runtime source: Automatic / Apple Sensor Capability resolved by the app: Shallow Resolved provider: Apple Sensor — Shallow Sample source: Apple Shallow CMWaterSubmersionManager.waterSubmersionAvailable: true Depth automation: available Provider start is called First provider event is received Submersion state: unknown No submersion event is received No depth measurement is received No temperature sample is received Provider state: error Raw error: Domain: CMErrorDomain Code: 105 Description: The operation couldn’t be completed. The relevant runtime failure is: CMErrorDomain 105 The app also does not appear in: Apple Watch Settings → General → Auto-Launch → When Submerged This is the key point that I cannot clarify from the documentation. My questions are: Is the entitlement com.apple.developer.submerged-shallow-depth-and-pressure sufficient for a watchOS app to appear in: Apple Watch Settings → General → Auto-Launch → When Submerged? Is the shallow depth entitlement sufficient to receive runtime events from CMWaterSubmersionManager, including submersion and depth measurements? Or is the full submerged depth entitlement required for: appearing in the “When Submerged” auto-launch list; receiving CMWaterSubmersionManager submersion events; receiving CMWaterSubmersionManager depth measurements? What does CMErrorDomain code 105 mean in the context of CMWaterSubmersionManager? If the shallow entitlement is sufficient, what other conditions could cause CMWaterSubmersionManager to return CMErrorDomain 105 before delivering any submersion or depth samples? To summarize: The shallow entitlement is present in the source entitlements file. The shallow entitlement is present in the signed Watch app. The shallow entitlement is present in the embedded provisioning profile. The built Info.plist contains WKSupportsAutomaticDepthLaunch = true. The built Info.plist contains WKBackgroundModes = underwater-depth. CMWaterSubmersionManager.waterSubmersionAvailable returns true. The app does not appear in the Watch “When Submerged” list. CMWaterSubmersionManager fails with CMErrorDomain 105 before delivering submersion/depth samples. Any help will be strongly appreciated. Thank you.

I've a question for you maybe you can help me. My watchOS app has: WKSupportsAutomaticDepthLaunch = true WKBackgroundModes = underwater-depth com.apple.developer.submerged-shallow-depth-and-pressure = true entitlement present in codesign and embedded provisioning profile The app uses the shallow depth entitlement, but it does not appear in: Settings → General → Auto-Launch → When Submerged. Is the shallow depth entitlement sufficient for appearing in the system underwater auto-launch app list, or is the full submerged depth entitlement required?
