title: App Crashes But No TestFlight Crash Report
body: <p>I have one user (with an iPhone 5) reporting that my app crashes on launch about 15 seconds after the screen goes black (the splash screen is black).  The user downloaded a TestFlight build where I included checkpoints in the App delegate, but I don't get evidence that those checkpoints are crossed, and I never get a crash report.</p>
  
  <p>I changed the entry point on the storyboard to a blank view controller, and now I can see that the checkpoints are being crossed.  It's occurred to me that Watchdog is suspending the app due to storyboard resources taking too long to load, but all the images are built in real-time as needed, with the exception of four tiny tab-bar icons.  There are several audio files but they are loaded on demand.  I can't think of any other resources that could be causing a delay.  No one else has reported this problem, and I'm stumped.</p>
  
  <p>Any insight appreciated, especially as to why I'm not seeing a crash report or checkpoints from TestFlight.</p>
