xcode firebase message error OSAtomicCompareAndSwapPtrBarrier

I have an application in ionic 3 (legacy) when building it I get the error in the Firebase Messaging library in this part of the file "GtalkExtensions.pbobjc"

if (!OSAtomicCompareAndSwapPtrBarrier(nil, worker, (void * volatile *)&descriptor)) {
      [worker release];
    }

Conflicting types for ‘OSAtomicCompareAndSwapPtrBarrier’

Declaration of ‘OSAtomicCompareAndSwapPtrBarrier’ must be imported from module ‘Darwin.libkern.OSAtomic’ before it is required

Implicit declaration of function ‘OSAtomicCompareAndSwapPtrBarrier’ is invalid in C99

How to solve this problem I already removed cocoapods completely and tested several versions and it didn’t help.

    I have upgraded everything firebase related to the latest version and the error is gone.
    Example: 

    "@react-native-firebase/analytics": "^17.5.0",
"@react-native-firebase/app": "^17.5.0",
"@react-native-firebase/crashlytics": "^17.5.0",
"@react-native-firebase/dynamic-links": "^7.5.1",
"@react-native-firebase/firestore": "^17.5.0",
"@react-native-firebase/messaging": "^17.5.0",
"@react-native-firebase/remote-config": "^17.5.0",

    it’s might be incompatible with Protobuf.
    maybe you can try to specific another version in Podfile.lock like

    - Protobuf (3.21.12)

    The problem is related to new Protobuf (3.23.X) library. If you want to fix your current version of Firebase without upgrading to the latest one you can pin a previous working version of ‘Protobuf’ in your Podfile:

    ...
target 'YourTarget' do
  project 'YourProject'
  ...
  pod 'Protobuf', '= 3.22.1' # Pinned version for Firebase Messaging
end

    Then remove Podfile.lock and run pod install.
