title: iOS Xcode compile error: unable to execute command: Segmentation fault: 11
body: <p>I have a project which compiled perfectly in the past, but after the last Xcode update (6.3.2) I get a compile error whenever I try to run it directly on a device. Building and Running it in the simulator works fine. The Archive function works fine as well. But no matter what device I connect or what iOS version the device is running, I always get the same compile error:</p>

  <ol>
  <li>It shows me random files that I'm supposed to submit to the bug report.</li>
  <li>I haven't made any code changes from a working version to the version causing the current problems and I even reverted to an earlier version which is live and running in the Appstore but still the same error.</li>
  <li>I have deleted xcode and installed again trough the app store</li>
  <li>I tried making changes to my code to maybe pinpoint any problems but since the source file of the problem changes every time, I don't really think anymore that it has anything to do with my code.</li>
  </ol>
  
  <p>This is driving me mad.
  Any help is much appreciated</p>
