Customize sign in with phone number

[LeonardoPasseri]

Hello,

As far as I understood the only way to provide phone number authentication is through FirebaseUI.

Unfortunately, it seems that ChatSDK doesn't allow to specify custom subclasses for FirebaseUI view controllers, since FirebaseUIModule assign itself to FIRAuth.delegate and returns an instance of FUIAuthPickerViewController, preventing the client code from specifying a custom auth picker view controller (and any other auth-related custom view controller).

However, FirebaseUI looks poorly customizable even if custom view controllers could be used (e.g. no clean way to customize sign in buttons).

Can you suggest a way to use a custom login view controller that provides phone number authentication?

Thanks

Hi @LeonardoPasseri the Firebase UI ChatSDK module is a very lightweight wrapper around Firebase UI. If you want to customize it you can just copy-paste those classes into your project.

Firebase UI is not very customizable as you said. But it's not hard to re-implement the UI using Firebase APIs.

For example, for phone auth you would follow this guide:

Hi, @bensmiley. I managed to customize the sign-in with phone number flow by forking FirebaseUI and making the needed changes. Thank you for your help.
