title: iMessage extension showing empty screen
body: <p>I created an iMessage extension. When I install it on one phone (via Xcode), everything works fine. Same with simulator.</p>
  <p>When I attempt to connect a friend's phone and launch the app, it shows a blank screen. I can't find a crash nor other information in the Xcode console nor the macOS console.</p>
  <p>I'm guessing the device is either too old (iPhone X), or the app is crashing on this phone for some reason.</p>
  <p>Any idea what's wrong?</p>
