The module names changed in the last major release. You'll have to import FirebaseAuthUI instead of FirebaseUI now.

[gallaugher]

The documentation needs to be changed online:
https://firebase.google.com/docs/auth/ios/firebaseui
It still refers to FirebaseUI, not FirebaseAuthUI.
Does FirebaseAuthUi cover GoogleAuthUI, or does one also need FirebaseGoogleAuthUI when using Google, or does FirebaseAuthUI cover this?

[morganchen12]

Thanks @gallaugher, I'll update those docs. You'll need FirebaseGoogleAuthUI when using Google.

[morganchen12]

The documentation has ben updated.

After adding https://github.com/firebase/firebase-ios-sdk in SwiftPackageManager I chose FirebaseAuth as a package that I want to add to my project.
Then import FirebaseAuthUI still resulted in No such module 'FirebaseAuthUI'.
Am I missing something?

UPDATE:
Just realised I was importing the wrong repo.
Instead I should add https://github.com/firebase/FirebaseUI-iOS. It would be nice to add that in the README though.
