SwiftUI Firebase: Sending a message to the mail - ios

Question

In the function I want to add sending a message to the confirmation email, if you confirm, then you get to Homescreen(), else SignUp().
What do I need to add to my code?
func register(){
if self.email != ""{
if self.pass == self.repass{
Auth.auth().createUser(withEmail: self.email, password: self.pass) { (res, err) in
if err != nil{
self.error = err!.localizedDescription
self.alert.toggle()
return
}
print("success")
UserDefaults.standard.set(true, forKey: "status")
NotificationCenter.default.post(name: NSNotification.Name("status"), object: nil)
}
}
else{
self.error = "Password mismatch"
self.alert.toggle()
}
}
else{
self.error = "Please fill all the contents properly"
self.alert.toggle()
}
}
SignUp() - View where registration takes place
Homescreen() - View where the message about successful registration appears

Answer 1

You can first try to sign the user in with email using following code:
Auth.auth().signIn(withEmail: email, link: self.link) { authResult, error in
// ...
}
If there is an error, present the error alert to the user.
If sign in was successful, you can use the following code to get the current user:
if let user = Auth.auth().currentUser {
}
And inside of the curly brackets just check if current user has already verified the E-Mail with user.isEmailVerified
If that is the case, then simply present your Homescreen
If current user has not verified his E-Mail yet, you can present an alert, where the user can choose if he wants to have the verification E-Mail sent out again. If that is the case, you can simply resend the E-Mail with
user.sendEmailVerification {error in
}
and the user will get his verification E-Mail or there can occur an error while sending the Email so you should handle that error aswell!
Good luck!
