[Bug] 'headerValue()' is unavailable in Swift: Use asyncHeaderValue()

[Kharion]

Description

Xcode is unable to build our game. We did not made any changes to Firebase or any other SDK since October 9th. The builds stopped working overnight with following error:

build/Pods/FirebaseAuth/FirebaseAuth/Sources/Swift/Backend/AuthBackend.swift:112:40: error: 'headerValue()' is unavailable in Swift: Use `asyncHeaderValue() async -> String?` instead.
      request.setValue(heartbeatLogger.headerValue(), forHTTPHeaderField: "X-Firebase-Client")
                                       ^~~~~~~~~~~
FirebaseCoreExtension.FIRHeartbeatLoggerProtocol:12:10: note: 'headerValue()' has been explicitly marked unavailable here
    func headerValue() -> String?

We use EDM 1.2.183, Firebase Unity SDK 12.3.0. Not even downgrade to 12.2.1 helps. Google Mobile Ads version 9.2.0 (unity package). This is very unfortunate since we are in the release week. Please give us workaround instructions.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

[yepMad]

The same happens here, even in builds that previously worked and were untouched.
invertase/react-native-firebase#8073

[argzdev]

Hey folks, thanks for bringing this to our attention and also linking the react native thread.

Let me bring this up to our engineers, and see if we can come up with a fix.

[yepMad]

I've found a workaround for this, based on the answers the React Native Firebase folks provided.

In /Firebase/Editor inside all the Dependencies.xml you have (eg. AppDependencies.xml, AuthDependencies.xml, FirestoreDependencies.xml) change the “version” of <iosPod ... /> to 11.4.0. This should solve the problem for now.

Example:

<iosPods>
    <iosPod name="Firebase/Auth" version="11.4.0" minTargetSdk="13.0">
    </iosPod>
</iosPods>

[a-maurice]

Thanks for suggesting that workaround for folks. Talking with the Firebase iOS team, they have just published FirebaseCoreExtension 11.4.1 this morning to revert the problematic change. If you run pod update on your project, or hopefully just do a build from Unity which might pick up the new pods, you should also be good to go.

[argzdev]

Hi folks, I tried creating a new project and adding FirebaseAuth dependency, so far the iOS built app is now pulling the correct transitive dependencies. I guess that verifies that the issue has been resolved. I'll go ahead and close this thread now. Thanks!
