[🐛] 🔥 Error: CocoaPods could not find compatible versions for pod "FirebaseCore" on build

[notnavindu]

Issue

Hello!

I am currently working on an expo project with react-native-firebase.

A bit of background context: I recently ran into this issue after upgrading my MacOS and xcode versions. Initially, I tried to fix the problem using the plugin approach mentioned here.

Unfortunately it was giving me the following error and failed.

Initial error

The above error occurred on expo SDK 50 and react-native-firebase V19. As per this comment i decided to upgrade my packages hoping to fix the issue.

I upgraded all my packages and expo to their latest versions. (versions shown below)

When I try to build the project I get the following error

❯ yarn prebuild
yarn run v1.22.21
warning [email protected]: The engine "pnpm" appears to be invalid.

⚠️  Something went wrong running `pod install` in the `ios` directory.
Command `pod install` failed.
└─ Cause: CocoaPods could not find compatible versions for pod "FirebaseCore":
  In Podfile:
    RNFBApp (from `../node_modules/@react-native-firebase/app`) was resolved to 21.0.0, which depends on

        FirebaseCore (~> 10.0)

pod install --repo-update --ansi exited with non-zero code: 1
✨  Done in 170.83s.

The error is there for all prebuild, run:ios and eas build --platform ios commands

Not sure why it's pulling in the wrong dependencies.

The RNFBMessaging.podspec specifies an unversioned transitive dependency on FirebaseCoreExtension here:

react-native-firebase/packages/messaging/RNFBMessaging.podspec

Line 42 in 9c94085

s.dependency 'FirebaseCoreExtension'

It does so because that dep is not always at the same version upstream, despite being current - it has been like this since v19.1 or so around here cb7ed0e

Perhaps you just need to do a pod repo update, I'm not sure

This does not reproduce in any build testing I've ever done so I'm unsure

[notnavindu]

Hey thanks for the response @mikehardy. The boringSSL part was a mistake and I removed it, along with doing a pod repo update. Issue still exists.

I also tried updating brew, cocoapods, and npx react-native-clean-project.

Also just tried to add this back in but nope.

s.dependency          'FirebaseCoreExtension', firebase_sdk_version

I didn't wanna mess with Podfiles too much as I am not very familiar with it :/

[mikehardy]

Something else must be pinning it somehow. All I can say is our e2e app, my work app, .and if you Google mikehardy rnfbdemo my build demonstrator are all fine

[notnavindu]

Hey it was an error on our end, these pods were pinned in the app.config.js some time ago for reasons I cannot remember :/ it is working now. Thanks for the help!
