title: Xcode 8: Loading a plug-in failed
body: <p>when launching Xcode beta 8 on a macOS Sierra beta I'm getting this error:</p>
  
  <blockquote>
    <p>Loading a plug-in failed.<br>
    The plug-in or one of its prerequisite plug-ins may be missing or damaged and may need to be reinstalled.</p>
  </blockquote>
  
  <p>After searching, it seems that the issue is related with python and the new security measures that Apple introduced after XCode Ghost.</p>
  
  <p>I couldn't find a solution, anybody can help?</p>
  
  <p><strong>EDIT</strong>
  By looking at the Xcode logs, I noticed that it has NOTHING (apparently) to do with Python.
  I see a whole bunch of
  *Requested but did not find extension point with identifier Xcode.**
  errors</p>
  
  <p>I have to say that I also have Xcode 7 installed on my machine.</p>
