title: Xcode stuck at "Processing Symbol Files"
body: <p>When I try to run my app on my device Xcode gets stuck on processing symbol files.</p>
  
  <p>I restarted the machine (I'm using VirtualBox), tried a different USB port, restarted the host computer, cleaned the build folder, tried a different project, updated Xcode to 8.2, tried to use Xcode 7.3 but nothing worked. My device does show in iTunes.</p>
  
  <p>I left iTunes open when I tried to run it on my iPad and then it said "<strong>Unable to copy symbol files</strong> - <em>unable to read required data from device</em>"</p>
  
  <p>Xcode 8.2 (latest currently) and iOS 10.1</p>
