Classification:Incorrect behaviour Reproducible:Always
 
After the release of Watch OS 8 and iOS 15, we've had issues with our enterprise app not launching anymore on the watch.

After following the steps here https://developer.apple.com/forums/thread/682775 and later the official documentation https://developer.apple.com/documentation/xcode/using-the-latest-code-signature-format, we still experience that xcode does not sign the watch and watch extension properly, only the iOS app.

I have tried the following workarounds:
* Added '--preserve-metadata' and '--generate-entitlement-der' to 'Other code signing flags'
* manually signing

The former does not work, watch and extension are still not signed with DER entitlement.
The latter works but is rather inconvenient.

My setup:
Mac OS Big Sur - 11.4 (20F71)
Xcode 12.5.1 (Still reproducible with Xcode 13)
Watch running WatchOS8
iPhone running iOS15

------- Please list the steps you took to reproduce the issue -----------
1. Create small iOS project
2. Add watch and watch extension target
2b. optional step: add --preserve-metadata and --generate-entitlement-der to 'Other Code signing flags'
2. Archive
4. Inspect .ipa

--------- What did you expect to happen? ------------------
iOS app, watch app and extension appex having a -6, -7 in its signature and being able to launch app on watch


------------ What actually happened? ------------------
Only the iOS app has -6, -7 signatures.. watch and extension does not. App on watch does not launch.

Issue fixed

Issue seems to have been resolved with Xcode 13.1. There's no release note to confirm it though...
