React Native Firebase Push Notification Crash Report Problem - ios

Question

I am building an app with React Native. With React Native Firebase, I am adding push notification functionality. When I open a push notification from quit state, the app opens and hangs at the splash screen for a while, and then crashes.
Here is the crash report from the device, symbolicated. Honestly, I am new to programming and so I am having trouble in interpreting below report. I assume that there is a problem with RNSplashScreen module or AppDelegate.m, but can't be sure.
Can anyone help me out in interpreting this and point me to what might be a root cause/where to look at?
Thanks!

Answer 1

I had the same issue after adding React Native Firebase to my project and found the answer in this issue: https://github.com/crazycodeboy/react-native-splash-screen/issues/397
The real cause is in the react-native-splash-screen. Firebase requires to change "Background modes" in your App's Capabilities, this causes react-native-splash-screen to go into loop in RNSplashScreen.m:
while (waiting) {
NSDate* later = [NSDate dateWithTimeIntervalSinceNow:0.1];
[[NSRunLoop mainRunLoop] runUntilDate:later];
}
You can find it in this part of the backtrace:
5 Foundation 0x00000001ae1b1df0 -[NSRunLoop+ 36336 (NSRunLoop) runMode:beforeDate:] + 232
6 Foundation 0x00000001ae1b1cbc -[NSRunLoop+ 36028 (NSRunLoop) runUntilDate:] + 92
7 myapp 0x00000001005d15f0 +[RNSplashScreen show] (in myapp) (RNSplashScreen.m:31) + 5641712
To solve the problem you need to modify your AppDelegate.m, replace
[RNSplashScreen show]
with
[RNSplashScreen showSplash:#"LaunchScreen" inRootView:rootView];
But be careful, if your project uses LaunchScreen.storyboard instead of LaunchScreen.xib, you can catch this error:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </private/var/containers/Bundle/Application/D22A78C5-5733-4511-85BF-217A3BAEB6AB/myapp.app> (loaded)' with name 'LaunchScreen''
In this case you need to create the new View named "LaunchScreen" and copy-paste here your launch view from the LaunchScreen.storyboard.
