title: After updating to Xcode 10.2 build gets black screen on testflight
body: <p>I had my app working perfectly. I've updated the Xcode to the latest 10.2 version and something weird happened (as usual with any update...)</p>
  
  <p>The app runs smoothly on the debugger. No issues at all!</p>
  
  <p>When I archive a version to testflight, that version shows the splashscreen then goes into black screen (without crashing) just stays in the black screen... does anyone know what might be happening here?</p>
  
  <p>thanks in advance</p>
