title: How does one (re)install xcode?
body: <p>I made the mistake of upgrading xcode and its been painful.</p>
  
  <p>I'm at my wits end trying to satisfy apples demand of "Rebuilding my app using the current public (GM) version of Xcode and resubmitting it."</p>
  
  <p>some details <a href="https://stackoverflow.com/questions/33047922/xcode-7-0-1-invalid-swift-support-cocoapods-how-to-fix">Xcode 7.0.1 - Invalid Swift Support - cocoapods HOW TO FIX?</a></p>
  
  <p>As far as I know I'm using the current public (GM). I'm using version 7.0.1 (7A1001), please someone tell me if thats not the current public (GM).</p>
  
  <p>I've tried just about every "solution" here, the error still persists.</p>
  
  <p>Now I'm down to reinstalling xcode as a last grasp. 
  Of course this process is cloaked in mystery, how do you go about "reinstalling" xcode? I've heard that xcode has a "large footprint" so it's just not a matter of trashing the app, is it?</p>
