Add Google Auth to SPM

[mamilov]

• Objective C or Swift: Swift
• iOS version: iOS 14.1
• Firebase SDK version: 7.11.1
• FirebaseUI version: master branch
• CocoaPods Version: Swift Package Manager

Step 3: Describe the problem:

When using with FirebaseUI with SPM, FUIGoogleAuth cannot be found in the project. Since I can find it in the spm packages, I assume that something is not exported right.

Steps to reproduce:

1. Add FirebaseUI with SPM
2. Try to import and use FUIGoogleAuth

Observed Results:

• Cannot find *FUIGoogleAuth' in scope

Expected Results:

• Can find and use FUIGoogleAuth

Can it be due to 'FirebaseGoogleAuthUI' missing in Package.swift?

Google Auth is not yet supported in SPM since one of the dependencies, GoogleSignIn, does not yet support SPM.

Thank you for reporting this; I've filed an internal issue b/189044410 to track this.

[mamilov]

A new version of googlesignin with spm support has been released: https://github.com/google/GoogleSignIn-iOS

[mamilov]

Is there an ETA for an update regarding GoogleAuth support?

[morganchen12]

Sometime this week, hopefully, though given the changes in GoogleSignIn 6 it's likely going to require a major version update.

Re-opening since this hasn't been released yet.
