Treat phone number like email in phone auth flow

[entaku0818]

• Swift4.2
• iOS version: 11
• FirebaseUI/Auth (5.2.2)
• FirebaseUI/Phone (5.2.2)
• CocoaPods Version: 1.5.3

Expected Results:

• I expect the following two actions

1. Anonymous user can signup by phone number. This user become phone "number number user" and have a user info when anonymous user.
2. Anonymous user can login by phone number, if phone number user was login in the past.

Relevant Code:

I think get Expected Results by the code below. However, I have a Expected Result 1 only. Why?

        let authUI: FUIAuth = FUIAuth.defaultAuthUI()!
        let authProvider: FUIAuthProvider = FUIPhoneAuth(authUI:authUI)
        authUI.providers = [authProvider]

        let phoneProvider: FUIPhoneAuth = authUI.providers.first as! FUIPhoneAuth

        phoneProvider.signIn(withDefaultValue: "", presenting:self) { (credential, error, callback) in

            if let error = error{
                print(error)
                return
            }

            if let credential = credential,let user = Auth.auth().currentUser {

                user.linkAndRetrieveData(with: credential) { (authResult, error) in
                    if let error = error {
                        print(error)
                        Auth.auth().signInAndRetrieveData(with: credential) { (result, error) in
                            if let error = error {
                                print(error)

                                return
                            }
                            self.navigationController?.dismiss(animated: true, completion: nil)

                        }
                        return
                    }
                    self.navigationController?.dismiss(animated: true, completion: nil)
                }

            }
        }

What errors are you running into when trying this? Phone auth is currently experiencing some issues.

Thank you for the response. This error message is below.

Error Domain=FIRAuthErrorDomain Code=17025 "This credential is already associated with a different user account." UserInfo={FIRAuthUpdatedCredentialKey=<FIRPhoneAuthCredential: 0x283d25470>, NSLocalizedDescription=This credential is already associated with a different user account., error_name=ERROR_CREDENTIAL_ALREADY_IN_USE}
Error Domain=FIRAuthErrorDomain Code=17051 "The SMS code has expired. Please re-send the verification code to try again." UserInfo={NSLocalizedDescription=The SMS code has expired. Please re-send the verification code to try again., error_name=ERROR_SESSION_EXPIRED}

Looks like you're running into two errors.

• The first error says the credential you're trying to link to your account is already associated with another account. You should handle this by just logging into that account and discarding the anonymous user.
• The second error says the SMS code has expired. Maybe you're going through the authentication flow too slowly?

I know.

I wanted to make the following logic When that phone number was using "sign in", if it was not using "signup."

I guess it's hard I think it would be good for the user input to "sms code" again when that phone number was using.

Thank you your help.
