title: WatchKit Extension Bundle ID Unavailable
body: <p>I've added a watch kit app to my iOS app and everything was working fine and running well until I wanted to share data between the two apps.</p>
  
  <p>Whenever I try to add the 'App Groups' capability on the watch kit extension, it tells me that my bundle ID (com.myrealappid.watchkitextension) is not available.</p>

  It also informs me that 'No matching provisioning profiles found' in the General tab, and if I try to fix it, it also says that the App ID (com.myrealappid.watchkitextension) is not available.</p>

  Logging into the members centre I can't find any reference to a bundle ID with the suffix 'watchkitextension'. I also can't re-add this bundle ID within the members centre because it seems to think it already exists as well.</p>
  
  <p>Has anyone come across this before or have any suggestion on how to fix it?</p>
