Current behavior

This is my code :

return FirebaseAuthentication.signInWithApple({ skipNativeAuth: true, scopes: ["name", "email"] }).then((result: SignInResult) => {
          const provider = new OAuthProvider('apple.com')
          const authCredential = provider.credential({
            idToken: result.credential.idToken,
            rawNonce: result.credential.nonce,
          });
         return signInWithCredential(getAuth(), authCredential)
.then((result: UserCredential) => {console.log(result.displayName}

Problem is that displayName null for new account...

I remove account in firebase console after every registration.

Expected behavior

I'm expecting to get displayName of Apple account where I can find firstname and lastname.

Apple provides the display name only once at signup.
Make sure you delete the Firebase user entry AND revoke the Apple ID access correctly.

[ludonoel1]

I did it ...

[robingenz]

Okay, I will take a closer look at it as soon as possible.

[ludonoel1]

Thanks. Do you have a working example maybe ? please, because it's urgent

[ludonoel1]

With version 5.1.0 it's working on Web but not for ios simulator

[robingenz]

It should work with the demo app. But the demo app does not use skipNativeAuth. So I don't know if it will help you.

There are currently a few open issues that I need to work through. If you want you can have your issue prioritized via a one-time sponsorship. Otherwise PRs are also welcome.

Finally I use this code:

let options: SignInWithAppleOptions = {
                clientId: 'cclientID', //
                redirectURI: 'handler', //
                scopes: 'email name',
              };
              
              return SignInWithApple.authorize(options)
                .then((result: SignInWithAppleResponse) => {
                  const provider = new OAuthProvider('apple.com')
                  const authCredential = provider.credential({
                    idToken: result.response.identityToken,
                  });
    const displayName = `${result.response.givenName} ${result.response.familyName}`
                 return signInWithCredential(getAuth(), authCredential)

Issue is that signInWithCredential doesn't return displayName. DisplayName is still null

[robingenz]

I am glad you found a workaround.
Does this problem occur on all 3 platforms? Or on which platforms did you test it?

[ludonoel1]

I use this above code for android and IOS,

and your code for Web

[robingenz]

I mean on which platforms does the bug with the @capacitor-firebase/authentication plugin occur? I have to debug it.

[ludonoel1]

On Ios and android. Sorry

[robingenz]

Oh, so you mean on Android & iOS?

[ludonoel1]

Yes :)

[robingenz]

Thanks 👍

[robingenz]

I just tested it and cannot reproduce your issue. When I delete the Firebase user entry and revoke the Apple ID access, the next time I sign in I get the display name.
