Error - The email address is badly formed. Xcode Swift Firebase - ios

Question

I'm building a UI interface with authentication as an iOS app. I've come a long way from where I was originally but I cannot get past this error. I don't understand what I'm compiling incorrectly. Please take a look and help me out if you can.
import UIKit
import Firebase
class SignUpViewController: UIViewController, UITextFieldDelegate
{
#IBOutlet weak var email: UITextField!
#IBOutlet weak var password: UITextField!
#IBOutlet weak var passwordConfirm: UITextField!
#IBOutlet weak var signUpButton: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
email.delegate = self
password.delegate = self
passwordConfirm.delegate = self
}
#IBAction func signUpAction(_ sender: UIButton) {
if password.text !=
passwordConfirm.text{
let alertController = UIAlertController(title: "Password Incorrect", message: "Please re-type password", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
else{
Auth.auth().createUser(withEmail: email.text!, password: password.text!){ (user, error) in
if error == nil {
self.performSegue(withIdentifier: "signupToHome", sender: self)
}
else{
let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}
}
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool { //delegate method
textField.resignFirstResponder()
return true
}
}
The goal is to then accept the user input from email.text and password.text and segue into the home screen after creating a new user in my Firebase console.

Firebase has its own email validation which is like this 'abc#somedomain.com' so you need to pass a email address like this other wise it will keep throwing this error.
