I am creating an application which authenticate user using PhoneAuth. In my application I have a function which let user add Email to his account But not meant that I authenticate user using Email and Password, I just want to add email to his/her account (auth.auth().currentUser).
Initially, I let user to add his/her email in textfield and then I start to logout user from his/her device in order to reauthentication otherwise, I cannot update user's email using auth.updateEmail(). But sadly, the credential always expired after I called func updateEmail().
This is how I signIn user and update Email
let credential = PhoneAuthProvider.provider().credential(withVerificationID: verficationID, verificationCode: code)
Auth.auth().signInAndRetrieveData(with: credential) { (result, error) in
guard let result = result else {
completion(false)
return
}
if error == nil {
guard let user = Auth.auth().currentUser else {
return
}
if UserDefaults.standard.getUserUpdatedEmail() {
user.reauthenticate(with: credential, completion: { (error) in
if error == nil {
user.updateEmail(to: newEmail, completion: { (error) in
if error == nil {
UserDefaults.standard.setUserUpdatedEmail(value: false)
completion(true)
//return true
} else {
completion(false)
//return false
print("Error validate email ",error?.localizedDescription ?? "")
}
})
} else {
completion(false)
// return false
print("Error reauthntication email ",error?.localizedDescription ?? "")
}
})
} else {
print("User is signed in \(result.user)")
print("This is userID \(result.user.uid)")
completion(true)
}
} else {
if let error = error {
print("Error during verification \(error.localizedDescription)")
}
completion(false)
}
}
I don't why the credential is expired too fast? I cannot figure it out how to update user email using PhoneAuthCredential. Is there any other techniques to do it?
