UITextFields keyboard not appearing in UIScrollview - swift

Question

I have 2 textfields as subViews of a contentView and the contentView is a subView of a scrollView. The textfields appear with no issue.But the problem I am having is when I tap or select the textfield to enter text neither a keyboard appears or the blue cursor, the textfields placeholder remains there. Is there something wrong with my constraints? How can I get the keyboard to appear and edit the text?
class SignInViewController: UIViewController {
private let scrollView: UIScrollView = {
let scrollView = UIScrollView()
scrollView.translatesAutoresizingMaskIntoConstraints = false
return scrollView
}()
private let contentView: UIView = {
let view = UIView()
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
private let emailOrPhoneTextField: UITextField = {
let textField = UITextField()
textField.translatesAutoresizingMaskIntoConstraints = false
textField.placeholder = "Email or Phone Number"
textField.textAlignment = .center
textField.backgroundColor = .red
return textField
}()
private let passwordTextField: UITextField = {
let textField = UITextField()
textField.translatesAutoresizingMaskIntoConstraints = false
textField.placeholder = "Password"
textField.backgroundColor = .yellow
return textField
}()
override func viewDidLoad() {
super.viewDidLoad()
setupScrollView()
setupTextFields()
}
}
extension SignInViewController{
private func setupScrollView(){
view.addSubview(scrollView)
scrollView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
scrollView.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true
scrollView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
scrollView.addSubview(contentView)
contentView.centerXAnchor.constraint(equalTo: scrollView.centerXAnchor).isActive = true
contentView.widthAnchor.constraint(equalTo: scrollView.widthAnchor).isActive = true
contentView.topAnchor.constraint(equalTo: scrollView.topAnchor).isActive = true
contentView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor).isActive = true
}
private func setupTextFields(){
contentView.addSubview(emailOrPhoneTextField)
contentView.addSubview(passwordTextField)
emailOrPhoneTextField.centerXAnchor.constraint(equalTo: contentView.centerXAnchor).isActive = true
emailOrPhoneTextField.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 25).isActive = true
emailOrPhoneTextField.widthAnchor.constraint(equalTo: contentView.widthAnchor).isActive = true
emailOrPhoneTextField.heightAnchor.constraint(equalToConstant: 44).isActive = true
passwordTextField.centerXAnchor.constraint(equalTo: contentView.centerXAnchor).isActive = true
passwordTextField.topAnchor.constraint(equalTo: emailOrPhoneTextField.bottomAnchor, constant: 25).isActive = true
passwordTextField.widthAnchor.constraint(equalTo: contentView.widthAnchor).isActive = true
passwordTextField.heightAnchor.constraint(equalToConstant: 44).isActive = true
}
}

Try this and check if it works:
extension ViewController{
private func setupScrollView(){
view.addSubview(scrollView)
scrollView.addSubview(contentView)
contentView.addSubview(emailOrPhoneTextField)
contentView.addSubview(passwordTextField)
NSLayoutConstraint.activate([
scrollView.topAnchor.constraint(equalTo: view.topAnchor),
scrollView.rightAnchor.constraint(equalTo: view.rightAnchor),
scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
scrollView.leftAnchor.constraint(equalTo: view.leftAnchor)
])
NSLayoutConstraint.activate([
contentView.topAnchor.constraint(equalTo: scrollView.topAnchor),
contentView.rightAnchor.constraint(equalTo: scrollView.rightAnchor),
contentView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor),
contentView.leftAnchor.constraint(equalTo: scrollView.leftAnchor),
contentView.widthAnchor.constraint(equalTo: scrollView.widthAnchor),
contentView.heightAnchor.constraint(equalTo: scrollView.heightAnchor)
])
NSLayoutConstraint.activate([
emailOrPhoneTextField.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 50),
emailOrPhoneTextField.rightAnchor.constraint(equalTo: contentView.rightAnchor, constant: -20),
emailOrPhoneTextField.leftAnchor.constraint(equalTo: contentView.leftAnchor, constant: 20),
])
NSLayoutConstraint.activate([
passwordTextField.topAnchor.constraint(equalTo: emailOrPhoneTextField.bottomAnchor, constant: 25),
passwordTextField.rightAnchor.constraint(equalTo: contentView.rightAnchor, constant: -20),
passwordTextField.leftAnchor.constraint(equalTo: contentView.leftAnchor, constant: 20),
])
}
}
