title: Cannot export Apple ID from Xcode 9
body: <p>I'm trying to export my Apple ID from within Xcode 9.</p>
  
  <p>The error message that appears says:</p>
  
  <blockquote>
    <p><strong>Couldn’t communicate with a helper application.</strong></p>
    
    <p>Try your operation again. If that fails, quit and relaunch the application and try again.</p>
  </blockquote>
  
  <p>I did restart everything and also recreated my certificate - without luck.</p>
  
  <p>My OS is macOS High Sierra.</p>
  
  <p>How to solve this?</p>
