[🐛] Firebase Crashlytics error in React -Native

[AfzalAghariya]

When I try to run command 'yarn ios' after doing all set up for firebase crashlytics and pod install after that I am getting below mentioned error

This is my firebase version for different libraries

"@react-native-firebase/analytics": "^21.2.0",
"@react-native-firebase/app": "^20.5.0",
"@react-native-firebase/crashlytics": "^21.2.0",
"@react-native-firebase/messaging": "^20.5.0"

@AfzalAghariya you are using an incorrect combination of firebase-ios-sdk and react-native-firebase

We test these things for cross-compatibility but only in certain combinations, and that strategy is valid because react-native-firebase expects to own the versioning on the transitive dependency of firebase-ios-sdk

We allow people to override the firebase-ios-sdk version for emergencies that we cannot foresee, but we explicitly say you are on your own if you do so:

https://rnfirebase.io/#overriding-native-sdk-versions

Using your own SDK versions is generally not recommended as it can lead to breaking changes in your application. Proceed with caution.

If you ever see an error in an iOS build about an "unrecognized selector" that means "hey, you are using code that seems okay but we can't find the symbol you want?" and if you have a problem finding symbols it is generally because a symbol was added in a new version but you are not getting the new version for some reason.

And that's what is happening here.

We note these things in the CHANGELOG, as we noted here https://github.com/invertase/react-native-firebase/blob/main/CHANGELOG.md#2100-2024-09-26 - firebase-ios-sdk v11+ required

Remove any version pins you have on firebase-ios-sdk in your Podfile, and / or analyze your Podfile.lock to see why firebase-ios-sdk < v11 is coming in and your project will build

There is no further action that will happen in this repository, as our current code does build with current firebase-ios-sdk as specified in this repo

[mikehardy]

Also, this is something you should never do - you should never under any circumstances mix versions of react-native-firebase:

"@react-native-firebase/analytics": "^21.2.0",
"@react-native-firebase/app": "^20.5.0",
"@react-native-firebase/crashlytics": "^21.2.0",
"@react-native-firebase/messaging": "^20.5.0"

I am not able to understand the issue , please help me out @mikehardy

@AfzalAghariya that comment is impossible to read, the formatting is impenetrable.

Github markdown allows you to place things in triple-backticks to format things so that people you attempt to collaborate with can read your posts

like this

I have told you what to do already, but will be more explicit:

"@react-native-firebase/analytics": "^21.2.0",
"@react-native-firebase/app": "^20.5.0",
"@react-native-firebase/crashlytics": "^21.2.0",
"@react-native-firebase/messaging": "^20.5.0",

This is invalid. It is the source of your problem. You are not following the versioning rules here, which are explained in the blog post I linked.

Use all one version at all times of react-native-firebase.

If you update them all to 21.2.0 your project will build.

[AfzalAghariya]

I updated them all to 21.2.0 ,but still the issue is there

[mikehardy]

after updating you will need to run pod install again, if you have not done that then you will not get the new firebase-ios-sdk transitive dependencies pulled down

If you have run pod install then you will need to investigate your Podfile to make sure you do not have an erroneous version pin for firebase-ios-sdk and/or you will need to investigate your Podfile.lock to determine why you are getting firebase-ios-sdk versions that are not v11+

I will be absolutely clear with you that this is a problem local to your project, there is no problem when using the correct transitive dependencies of firebase-ios-sdk that we specify in react-native-firebase, with current react-native-firebase code

Further support on this issue will not be available as I've given you all the direction I possibly can - the answer will be somewhere in your Podfile / Podfile.lock
