title: Xcode always recompiles everything every time I build
body: <p>I'm working on a <code>Swift 2.3</code> project using <code>Xcode Version 8.0 (8A218a)</code>, I use <code>Cocoapods 1.0.1</code> for dependency management.</p>
  
  <p>I don't know what happens but every time I hit <code>build</code> or <code>build &amp; run</code>, wether there is a modification in a file or not, the compiler will take 2-3 minutes to recompile what seems to be all the sources files of my project.</p>
  
  <p>I found this thread on Apple's forum (<a href="https://forums.developer.apple.com/thread/44406" rel="nofollow">https://forums.developer.apple.com/thread/44406</a>) that doesn't solve my issue (I applied <code>Compiler Default</code> settings to both my project and the <code>Pods</code> sub-project).</p>
  
  <p>I have no idea what's happening and it's driving me crazy. Any lead welcome :)</p>
  
  <p>Thanks!</p>
