title: XCode 5.1.1 freezes when running app on device, works on simulator
body: <p>When I'm trying to run my app on simulator, everything works as expected. </p>
  
  <p>However, when I run on a device (iPhone 5S):</p>
  
  <ol>
  <li>The app icon appears on device (and I can open the app manually), but XCode won't launch the app as normally.</li>
  <li>XCode shows "Running [appName] on iPhone".</li>
  <li>Console is empty, no any messages at all.</li>
  <li>XCode freezes, the <em>beachball</em> appears and MacBook gets really slow and unresponsive. The only way to recover from this is to force shutdown and restart my computer.</li>
  </ol>
  
  <p>XCode version is 5.1.1 and OS X 10.9.4. My iPhone 5S has iOS 7.1.2 and I've set Base SDK as "Latest iOs (iOs 7.1)" in XCode Build Settings.</p>
  
  <p>Do you have any idea what could cause this? I already tried reinstalling XCode and checking out my project from svn to another path.</p>
