SwiftUI Firebase: Sending a message to the mail

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!
