title: Xcode cannot build IPA file
body: <p>I am trying to build a file IPA by Xcode 6.1.1. But my Xcode say:</p>
  
  <blockquote>
    <p>"The password supplied for the account @"xxx" was rejected.Please make
    sure that your password is correct in the Accounts preference pane"</p>
  </blockquote>
  
  <p>What's happen to my Xcode? I have to update to 6.2, right?</p>
