title: Xcode 8.0 Swift 3.0 slow indexing and building
body: <p>I've installed Xcode 8.0 and converted Swift 2.2 to 3.0 (that process also took a lot of time, I just left my Mac running all night). I have not a big project (about 20 files). I am also using <code>Pods</code>. Indexing of previous Xcode version (&lt; 8.0) worked fast but now, after upgrade, the progress bar is stuck on one position (I am already waiting for an hour).</p>
  
  <p>Things I've tried that didn't help me:</p>
  
  <ul>
  <li>Cleaned the <code>DerivedData</code> folder and restarted Xcode</li>
  <li>Cleaned the project and restarted Xcode</li>
  <li>Deleted <code>Pods</code> directory with <code>&lt;project&gt;.xcworkspace</code> and then installed again</li>
  <li>Restarted Mac</li>
  <li>Tried build project without Pods</li>
  <li>Reinstalled Xcode</li>
  <li>Tried on another Mac with cloned project</li>
  </ul>
  
  <p>It is really not cool to make such releases of software when developers have to spend hours on solving such ridiculous problems. It is very disappointing.
  Any ideas how to fix this?</p>
