XCode build error: Undefined symbols for architecture x86_64: "_FIREmailAuthProviderID"

I have been trying to integrate FirebaseAuth based on following guide: https://firebase.google.com/docs/auth/ios/firebaseui

As I only have enabled Sign-in with Google, I have added pods like,

  pod 'FirebaseUI/Auth'
  pod 'FirebaseUI/Google'

And installed Pods from Terminal.

When Pods get installed properly, I opened workspace, cleaned build (also removed contents from DerivedData) and tried to build the app for Simulator which gave me error and my build failed.

Error: Undefined symbols for architecture x86_64:
  "_FIREmailAuthProviderID", referenced from ...

Full error log and screenshot is attached below.

Full error log

I have also tried to integrate full Pod, like,

pod 'FirebaseUI'

That too gave me build errors.

I have tried other solutions available online but this library is integrated via CocoaPods and few online solutions are not applicable to my scenario. However, I have not yet reached to any solution for the issue.

Please let me know if there is any solution to this issue or not. I will also try to integrate this framework manually.

I am using XCode 12.

    As mentioned on this issue comment: https://github.com/firebase/FirebaseUI-iOS/issues/928

    pointing to latest pods resolved the issue.

    Like,

    pod 'FirebaseUI/Auth', '~> 8.0'

  2. 0

    First try it…**

    I had the same issue with Carthage, but I resolved it.

    Please check if the PromisesObjc.framework is added to your project (make sure the correct target is selected). In my case it wasn’t because I believe this is a new framework they’ve added recently. It goes without saying that “Do Not Embed” should be selected under Frameworks, Libraries and Embedded Content”.

    Second try it…

    pod file in Framework and Library section add this :- Accelarate framework

    Clear derived data and run app

    I hope this helps, let me know 🙂
