react native crashes on device

I'm starting with React Native, everything works fine in the iOS simulator. I decide to try it on a device.

The app launches, I can play with it, I close/reopen it around 4 or 5 times, and then somewhat randomly the app crashes on Launch Screen (the one with "Powered By React Native"). It just shows the screen, and the app crashes to the iPhone home screen.

Any idea how I can further debug that?

Edit: I added Bugsnag in my AppDelegate.m, but bugsnag doesn't detect anything when the app crashes.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  NSURL *jsCodeLocation;

  [BugsnagReactNative start];

  // Rest of code  


I came across this issue today. Read a few SO posts and saw one guy mentioned if your app launches and hangs on the splash screen and then crashes with no error it probably has something to one of your npm dependencies.

After digging deeper i saw the react packager was throwing the error

This error is caused by a @providesModule declaration with the same name across two different files.

To fix

  1. check / clean up dependencies(check for same name declerations)

  2. rm -rf node_modules

  3. rm -rf $TMPDIR/react-*

  4. npm i

I had this problem also, what triggered it for me though was updating react and react-native.

I did a build after updating and then I experienced the same issue. I downgraded back to the previous versions of react and react-native, but that didn't work for me.

I tried removing node modules, and reinstalling, that didn't help. Then I noticed that when I was building: react-native run-ios,

the files in ios/build were not updating

I rm -rf ios/build/ and then I react-native run-ios and the ios/build folder populated. My app ran fine after that.

  • build the app in debug mode and use remote js debugging to see the error thrown while the app crashes.
  • The app crashes before the JS is even loaded. I tried to add Bugsnag to see what happens but I receive no crash report when the app crashes.
  • @amaurymartiny i have the same issue! did you find a solution to this?
  • @Zolve I installed Bugsnag and, but didn't find anything. I created a fresh project and now everything works fine.
  • just wondering: did you find any solution by now?
  • Did anyone find out any particular dependencies that were causing this error?

  • @mharris7190, i believe this is because the app takes too long to load in the debug mode on iOS. I had the same issue
  • is it because of the linking or what? , also have you tried linking it manually?
