问题
When getting an exception with React Native on iOS, I get this error screen with white background. You can see by the tapped cell that it actually has the exception stack, only with a white background. Not sure why's happening, but is there a way to fix? On Android the screen has red background (hence working as expected.)
Running React Native 0.48.3.

Found out why it was happening (At least in my case)
My team implemented a new launch screen as a .storyboard file, and that was causing the white screen.
If you change that launch screen for a .xib file it should work.

I can't figure out how to solve this issue, but a work around that I found is to enable Debug > Color Blended Layers for the Simulator. This gives some contrast to the screen, allowing you to make out the text. This problem happens to me on the iPhone X simulator, I haven't tested the other devices.

The problem was that react-native-navigation failed to load the Storyboard file caused the window to be loaded with empty rootViewController. It is now fixed in react-native-navigation latest version.
