[🐛] v24.1.0 Crashes on iOS

[birdofpreyru]

I have an existing app, using

    "@react-native-firebase/analytics": "^24.0.0",
    "@react-native-firebase/app": "^24.0.0",
    "@react-native-firebase/app-check": "^24.0.0",
    "@react-native-firebase/auth": "^24.0.0",
    "@react-native-firebase/database": "^24.0.0"

after bumping up these packages to the latest 24.1.0 the app started to sporadically crash on start-up on iOS, with the following error trace captured by Sentry:

googling for ODCConversionService I found this — firebase/firebase-ios-sdk#15961, so... perhaps it is a regression in Firebase SDK for iOS, or some change in the SDK not correctly updated for in RNFB. Yeah... the downgrade from v24.1.0 back to v24.0.0 (while keeping in place all other changes done between app versions) helps to avoid the issue.

@birdofpreyru sorry I didn't see this immediately - there was a firebase-ios-sdk update included in the 24.0.0 -> 24.1.0 delta, but it was partial, that is it did not take firebase-ios-sdk all the way to current since moving past 12.11.0 requires a newer Xcode and that's a breaking change we weren't ready to release yet.

It appears to be fixed in 12.12.1 upstream but that's past the "newer xcode needed" break in 12.12.0 so this is unfortunate.

I think the right thing to do here is likely to revert the firebase-ios-sdk update on our 24.x.x stable release series then when we release v25 with the final typescript migrations (the main breaking change coming up) we can include a version of firebase-ios-sdk that contains the fix for this

For you, given you are likely on a newer Xcode, you can also use our overrides to adopt a newer firebase-ios-sdk at your option / if you need it - I'll consider you an advanced user and assume you've done that before so are familiar with it. I'm not aware of any incompatibilities though I'm aware of this bug now, at least...

24.1.1 is out with a firebase-ios-sdk revert back to 12.10.0 to revert this until we can roll all the way forward

Thanks again @birdofpreyru
