Firebase Email Authentication iOS: "The email is badly formatted" - ios

Question

Attempting to create a Firebase login/signup but no matter what I enter into the email textfield it prints the error "The email address is badly formatted", even if its a valid email. Also I'm a beginner so...sorry about the format. This is the code:
import UIKit
import Firebase
import FirebaseAuth
class SecondViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// FirebaseApp.configure()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBOutlet weak var username_input: UITextField!
#IBOutlet weak var password_input: UITextField!
#IBOutlet weak var signupButton: UIButton!
#IBOutlet weak var segmentControl: UISegmentedControl!
#IBAction func doSignUp(_ sender: Any) {
let email = self.username_input.text
let password = self.password_input.text
if email != "" && password != ""
{
if segmentControl.selectedSegmentIndex == 1 //signup
{
Auth.auth().createUser(withEmail: email!, password: password!, completion: { (user, error) in
if error == nil {
print("You have successfully signed up")
// Goes to main page
let vc = self.storyboard?.instantiateViewController(withIdentifier: "Home")
self.present(vc!, animated: true, completion: nil)
self.performSegue(withIdentifier: "segue", sender: self)
let request = Auth.auth().currentUser?.createProfileChangeRequest()
request?.displayName = email
}
else {
if (error?.localizedDescription) != nil
{
// 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)
print(error?.localizedDescription as Any)
let myError1 = error?.localizedDescription
print(myError1!)
}
}
})
}
}
if segmentControl.selectedSegmentIndex == 0 {
//login
Auth.auth().signIn(withEmail: self.username_input.text!, password: self.password_input.text!, completion: { (user, error) in
if user != nil
{
self.performSegue(withIdentifier: "segue", sender: self)
//sign in user
}
else
{
if (error?.localizedDescription) != nil
{
_ = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let myError = error?.localizedDescription
print(myError!)
}
else {
Auth.auth().signIn(withEmail: self.username_input.text!, password: self.password_input.text!, completion: { (user, error) in
if user != nil
{
self.performSegue(withIdentifier: "segue", sender: self)
//sign in user
}
else
{
if (error?.localizedDescription) != nil
{
_ = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let myError = error?.localizedDescription
print(myError!)
}
}
}
)}
}
}
)
}
}

My code For Reference have a look
//Outlets
#IBOutlet weak var emailTextField: UITextField!
#IBOutlet weak var passwordTextField: UITextField!
//Sign Up Action for email
#IBAction func createAccountAction(_ sender: AnyObject) {
let email = emailTextField.text
let pass = passwordTextField.text
if emailTextField.text == "" {
let alertController = UIAlertController(title: "Error", message: "Please enter your email and password", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
present(alertController, animated: true, completion: nil)
} else {
Auth.auth().createUser(withEmail: email!, password: pass!) { (user, error) in
if error == nil {
print("You have successfully signed up")
//Goes to the Setup page which lets the user take a photo for their profile picture and also chose a username
let vc = self.storyboard?.instantiateViewController(withIdentifier: "Home")
self.present(vc!, animated: true, completion: nil)
} 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)
}
}
}
