React Native app crashing due to assertion error

[tclarke-scottlogic]

Started experiencing this crash today, have not encountered it before:

Build and run project in Xcode

Works for a while, then suddenly exits the app:

In system log, I see this:

Please provide repro (steps or code) on how to reproduce this. For me, it seems that it's unrelated to react native.

I just started getting this on a release build. Not sure if this is related but same error and all. Here are some more logs...

The best repro steps I can think of that is giving me this is just set an app to release mode and try running it on the simulator. I'm not getting any other logs for this either.
RN 0.55.4

Was a solution ever found? Happens to me only on release when upgraded to RN 0.56.0

Happening to us as well, only on iPhone X inside Expo or in the native built app.
Not finding much help here.
I know this is closed, but I have an App Store app that experiences it on iPhone X if that's any help.

This was the follow up, the crash was found to be in the iOS SDK. My fix was to rename a property of the data object from "notification", as it was somehow getting confused on the simulator about which notification was the one it was supposed to process.

I just rant into very much the same problem, but we are not using firebase

[PurnimaNaik]

@macnibblet did you find a solution? I have the same issue

[rimiti]

Is anyone has information about this issue ?

[Abramovick]

I'm not using Firebase but I'm also facing the same problem

[treynolds110]

I've also just encountered this issue. Any updated information?

This fixed it for me, can't speak to anyone else.
