title: Enable BitCode error Xcode 7
body: <p>I have tried to compile my app with <code>Xcode 7 beta</code>, and i receive this error:</p>
  
  <pre><code>-U and -bitcode_bundle (Xcode setting ENABLE_BITCODE=YES) cannot be used together
  </code></pre>
  
  <p>if I disable it in the config settings all works fine, but it's fine to disable it? what I have to do?</p>
