App is crashing on Launch Screen

When I’m testing my app on develop mode, everything is ok, but when I’m sending a test flight version of my app to the app store my app is crashing at Launch Screen and I have to open the app from recent list of iPhone.

When i run the app with Release mode i get the following error :

Getting the same issue after ungrading to iOS11 and react-native 0.48

[alenFMF]

I had exactly the same issue, the same type of a crash. It turned out to be due to use of the deprecated View.propTypes.style in one of the imported libraries. See:

https://github.com/facebook/react-native/issues/16542

By the way, you can test release builds before sending it to Testflight or Appstore in Simulator:
react-native run-ios --configuration Release
