I'm new to RN and trying to debug why the app crashes with no error message. The splash screen comes up, then the green bar on top, then it crashes. There's no message in the metro terminal. The app runs fine if i run it directly from xcode.
Are there some error logs somewhere else?

I've been given a new React Native app to maintain and whenever I build it or run it in the simulator, I get the "Application has not been registered" error. There are no other errors in the console before this message (although there are some warnings). I can't find any code issues as if the error message is dismissed in the simulator, the app runs fine so the bundler is running correctly, although on an actual device, this registers as a crash on open.
I'm running in the simulator using react-native run-ios from the project root. Builds for running on actual devices is managed by Fastlane.
My app doesn't make an explicit call AppRegistry.registerComponent due (I think) to the way react-native-navigation is set up, so most of the info online about this error doesn't apply.
Where should I go next to figure this out?
When I want to run my react-native app with the command 'expo start', my app is built in the expo app. The emulator then displays 'building app ...%'.
I now have the problem that the expo app closes immediately when it reaches 100% but it does not give an error code.
I have already tried 'expo r -c' as well as deleting the android emulator data.
Can someone help me with this?
My React Native app works properly on Android. However for the iOS side/version of my React Native app, the SPLASH SCREEN shows up and gets stuck there.
I have put a console.log output on the componentDidMount of the First Screen of my App.
I have tried to use the SHAKE option on the iOS Simulator but for some reason the debug screen does not show up.
I would like to check why the app freezes but I don't even get any error showing on the simulator. I'm guessing that there might a error/feedback from the system in the console output but I don't know how to go to the debugging screen where the console.log will show up when one runs react-native run-ios.
How to display the screen/console where the console.log("WHATEVER") I put on the code will display its output????
