title: App Crashes Only On Testflight Build
body: <p>I have created an app on swift and tested it extensively using iPhone 6, iPhone 6 plus and iPhone 5 devices and all the simulators offered in Xcode. The app runs fine and does not crash when uploaded locally. (iOS 8)</p>
  
  <p>I finally submitted a build for Testflight. The app consistently crashes at the same place after downloading the app through the Testflight build. </p>
  
  <p>Is there a known issue where uploaded builds run differently than locally created builds? And how can I debug the issue with the Testflight build? </p>
