"react-native-splash-screen": "^3.0.9",

What platform does your issue occur on? (Android/iOS/Both)

iOS

Describe your issue as precisely as possible :

1. Steps to reproduce the issue or to explain in which case you get the issue

The issue usually happens when I submit the app for release to TestFlight. At the moment it's being rejected, cause they only receive a blank screen. I'm unable to reproduce the bug locally.

2. Interesting logs

Join a screenshot or video of the problem on the simulator or device?

Show us the code you are using?

I'm having the same bug.
Everything works fine in debug / release mode on simulator / real device but it fails when the builds comes from Testflight.

What you could do is look at your device crash logs (CMD + SHIFT + 2 in Xcode with your device plugged in). From my logs it seems that l31 of the RNSplashScreen.m is responsible for the crash:

This very same line was already discussed because of BAD ACCESS issue a year ago: https://www.bountysource.com/issues/49406480-splashscreen-show-crashes-with-exc_bad_access

Apparently the app gets killed by the OS because it takes too much time to load. Maybe the loop does not stop early enough (in my case I call RNSplashScreen.hide() very late in my react-native code). Check this SO issue for more info: https://stackoverflow.com/questions/50186258/app-crash-exception-type-exc-crash-sigkill-termination-reason-namespace-spri.

I'll try to dig a bit !

I just read this thread that talks about a related issue: https://forums.developer.apple.com/thread/88529.
In their case it was the OS that was not handling correctly the end of a background task, but still it helps understand a bit more what's happening for us :)

I experience the same issue. Any update on this?

[code4cake]

I was the one that had posted the issue. I have not dig more into it, cause it sort of disapear on my end and I could not tested anymore.

I can confirm this bug and it seems to only happen on testflight builds for us. It is a showstopper unfortunately.

Any luck here from anyone? Started to hit this as well

[corelmax]

Same here, any luck?

FYI, I will try to use [RNSplashScreen showSplash:@"LaunchScreen" inRootView:rootView]; instead of [RNSplashScreen show]. You just have to create a View (.xib) via Xcode.

It seems like it's fixing the problem since it won't go into the Run Loop that was causing the crash.

EDIT: I confirm that you can workaround this issue by using the showSplash:inRootView: method instead of show (cc @corelmax @chevonc @mcorner @SebiVPS @colaskirschoff )

@ou2s

Just to confirm. You are saying you fixed the issue by using

[RNSplashScreen showSplash:@"LaunchScreen" inRootView:rootView];

Instead of

[RNSplashScreen show]

Or did you use something else IE showSplash:inRootView:

[Fausto95]

Facing the same issue here

EDIT: I just figured out that the issue wasn't related to react-native-splash-screen directly.

I can confirm using :
[RNSplashScreen showSplash:@"LaunchScreen" inRootView:rootView];
instead of
[RNSplashScreen show]

fixed crash for me.

Yes I confirm.

FYI, showSplash:inRootView: is not something else. It's the method name in Objective-C used in this code: [RNSplashScreen showSplash:@"LaunchScreen" inRootView: rootView].
Another example is: show is the method name in [RNSplashScreen show].

[dkoprowski]

Looks like [RNSplashScreen show] has some strange while (waiting) => while (true) in its code. The other method [RNSplashScreen showSplash:@"LaunchScreen" inRootView:rootView]; has a bit different code. I think it fixes issue for me as well.

Same here, Any solution ?
