title: Register an App ID
body: <p>I'm trying to publish my first app on the AppStore. In order to do that I am trying to add an iOS App ID to my identifiers. My issue is that I always get the following error message:</p>
  
  <blockquote>
    <p>There were errors in the data supplied. Please correct and re-submit.</p>
    
    <p>An App ID with Identifier 'com.myTeam.myApp' is not available. Please
    enter a different string.</p>
  </blockquote>
  
  <p>I verified if the App IDmatched my bundle ID in Xcode and it's the case. </p>
  
  <p>How can I fix this issue ?</p>
