iPhone 16 pro

I will add that the following error is logged on the phone shortly after starting the workout: Error Domain=com.apple.healthkit Code=554 Primary session is unreachable. UserInfo={NSLocalizedDescription=Primary session is unreachable.} in workoutSession(_:didReceiveDataFromRemoteWorkoutSession:):

15.8 isn't available as a platform in xCode, but 15.5 is. Yes, the iPhone 7/15.5 simulator works, but that doesn't resolve the issue with connecting a physical iPhone 7 with iOS 15.8 repeatedly fails.

@Vision Pro Engineer I did some more digging and it seems clear that the ImmersiveSpace gets backgrounded as soon as the FaceTime call gets initiated from the SharePlay UI. Again; that only happens in TestFlight environment. Maybe as a workaround I can try first dismissing the immersive space manually and then restarting it once the .activate() call has finished. Not great but I'm not sure if there is another way currently. Here a full video of whats happening: https://jumpshare.com/s/dOcSWPmHIPaiVBM3rE8v

There are a number of Bluetooth related fixes in iOS 26.1 on iPhone 17. Please test with the current 26.1 beta 3, and see if the issue continues for your app/device. If it does not seem to be fixed, then we'd need specific information about the issue. We need a specific diagnostic log. Please go to https://developer.apple.com/bug-reporting/profiles-and-logs/ and follow the instructions for Bluetooth for iOS to install a logging profile on your device. Then reproduce the issue, and follow the instructions at the above link to create a sysdiagnose. In that case, please open a bug report, include the sysdiagnose from above step, any other logs you might have, and sample code or models that reproduce the issue, and post the FB number here once you do. Bug Reporting: How and Why? has tips on creating a successful bug report. Important: For feedback related to a specific framework or API, select Developer Technologies & SDKs as your Topic, then select the specific technology and relevant OS. For feedba

Same here. We're getting this message in all our iPhones. Even after uninstalling and installing Testflight again. We open, press continue and the error message pops up. We are based in Germany. Any idea on how to fix this?

I compiled a Swift SDK library using Xcode 26 and gave it to someone else. When they import the library using Xcode 16, they get an error. How can I fix this?

I have updated the system to iOS 26.1 beta 3, and I am still unable to connect to Bluetooth. Everything is the same as before. I have submitted feedback using the same Apple ID on the phone experiencing the issue, and I included the system logs and Bluetooth logs. Please investigate as soon as possible.@Engineer

Since the minimum of deployment version that Xcode 26 supports is iOS 15.0, according to Gemini, I suppose, it should recognize your phone. And you are not able to run the iPhone 7 Simulator?

Please update to Xcode 26 to developer with iPhone 17. — Ed Ford,  DTS Engineer

Thanks for the quick response @Vision Pro Engineer ! I've filed FB20701196 with a minimal reproduction project. I created a simplified test app based on the structure of Apple's Building a guessing game for visionOS sample, and it has the exact same issue in TestFlight. The immersive space transitions to background state when FaceTime appears, but works fine in local builds. My FB includes: Since a clean implementation following the sample code structure hits this same issue in TestFlight, it seems like a platform bug rather than something wrong with my code. This is blocking our SharePlay launch, so really hoping for a fix soon. A public TestFlight link is attached to the radar but awaiting review. There are also screen recordings. Thank you!
