my Signup controller won't display email text fields. - swift

Question

I have been trying to programmatically create two separate view controllers in which I have a login, and sign up view controller. While my initial view controller, Login allows me to see the email/password text field, my sign up controller does not. I have plugged in the correct information however when I run my application, it is blank. I will post my code below, can anyone help me solve this issue?
let emailTextField: UITextField = {
let e = UITextField()
let attributedPlaceholder = NSAttributedString(string: "Email", attributes:
[NSAttributedStringKey.foregroundColor : UIColor.white])
e.textColor = .white
e.attributedPlaceholder = attributedPlaceholder
e.setBottomBorder(backGroundColor: GREEN_Theme, borderColor: .white)
return e
}()
let passwordTextField: UITextField = {
let p = UITextField()
let attributedPlaceholder = NSAttributedString(string: "Password", attributes: [NSAttributedStringKey.foregroundColor : UIColor.white])
p.textColor = .white
p.isSecureTextEntry = true
p.attributedPlaceholder = attributedPlaceholder
p.setBottomBorder(backGroundColor: GREEN_Theme, borderColor: .white)
return p
}()
override func viewDidLoad (){
super.viewDidLoad()
view.backgroundColor = GREEN_Theme
func setupFileComponents() {
setupEmailField()
setupPasswordField()
}
func setupEmailField() {
view.addSubview(emailTextField)
emailTextField.anchors(top: nil, topPad: 0, bottom: nil, bottomPad: 0, left: view.leftAnchor, leftPad: 24, right: view.rightAnchor, rightPad: 24, height: 30, width: 0)
emailTextField.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
}
func setupPasswordField() {
view.addSubview(passwordTextField)
passwordTextField.anchors(top: emailTextField.bottomAnchor, topPad: 8, bottom: nil, bottomPad: 0, left: emailTextField.leftAnchor, leftPad: 0, right: emailTextField.rightAnchor, rightPad: 0, height: 30, width: 0)
}
Thank you in advance.

You should move setupFileComponents, setupEmailField, setupPasswordField out of viewDidLoad then you have to add te calls in viewDidLoad like that:
override func viewDidLoad (){
super.viewDidLoad()
view.backgroundColor = GREEN_Theme
setupFileComponents()
setupEmailField()
setupPasswordField()
}
