title: Only crashing on Testflight
body: <p>We're using TestFlight to send out pilots of our app.</p>
  
  <p>There's a part of the app that is crashing, and we had a lot of trouble reproducing the crash. The code their is fairly simple.</p>
  
  <p>It turns out that the users who got the App via TestFlight get the crash, while if you build the app and install it using the IDE it doesn't crash!</p>
  
  <p>Anyone have ideas about what might be causing this? </p>
  
  <p>Any ideas for workarounds? We don't want to stop using TestFlight. </p>
