Long story short, I had my App and Watch app already uploaded to the app store. However, I needed to add a WatchConnectivity to have App to Watch communication.
At the beginning My app bundle id was: com.x My watch bundle id was: com.x.watchkitapp
However, while developing Watch Connectivity, I noticed that my Apps are not connected unless I changed it to com.x.watchkitapp -> com.x.watch
However after changing it I cannot submit my bundle anymore.
I'm getting Asset validation failed error
Invalid Bundle Identifier. Attempting to change bundle identifier from com.x.watchkitapp to com.x.watch is disallowed for bundle x.app/Watch/WatchX Watch App.app. (ID: 75a4621a-7e28-411d-a2a7-84674e460656) Any ideas how this could be solved?
