If you have a lot of textfield components my be it could be better to use an outlet collection, linking textfields and setting Return Key from interface builder

@IBOutlet var formTextFields: [UITextField]!

override func viewDidLoad() {
  for textField in formTextFields {
    textField.delegate = self
  }
}

extension RegisterViewController: UITextFieldDelegate {
  func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    if let componentIndex = formTextFields.firstIndex(of: textField) {
      if textField.returnKeyType == .next,
        componentIndex < (formTextFields.count - 1) {
        formTextFields[componentIndex + 1].becomeFirstResponder()
      } else {
        textField.resignFirstResponder()
      }
    }
    return true
  }
}
