What worked for me is changing the "iCloudKey-Value Store" key in the iOS entitlements file to $(TeamIdentifierPrefix)$(CFBundleIdentifier).watchkitapp The same key in the watchOS entitlements file of course should then be left unchanged as $(TeamIdentifierPrefix)$(CFBundleIdentifier) No signing issues.

Same issue. Programmatically changing @FocusState is not working on 15A240d / watchOS 10.
