title: React Native AppStore release - view unhandled JS Exceptions
body: <p>I've got an react native app that's been released to the AppStore.</p>
  <p>According to the Crash reporting that you get with XCode, I can see that there have been some crashes. I can then download the symbol files for these and open the crash in XCode.</p>
  <p>However, all I see is that there was an unhandled JS exception:</p>
  <p><a href="https://i.stack.imgur.com/nNAfI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nNAfI.png" alt="Xcode showing me where the crash happened" /></a></p>
  <p>What I can't work out is how to see the contents of the unhandled JS exception - all I can see is where in the RN native code it was handled. It goes to a method called <code>RCTFatal</code> which just seems to throw a <code>RCTFatalException</code> with the details - is this not captured by Apple for me to view, or is there some additional config I'm missing?</p>
  <p>Thanks</p>
