I know you can che

Answer 1

I wrote extension for the same. To provide Password toggle.

1. In your Assets first add images that you want for toggle.

2. Add following Extension for UITextField.

   extension UITextField {
   fileprivate func setPasswordToggleImage(_ button: UIButton) {
       if(isSecureTextEntry){
           button.setImage(UIImage(named: "ic_password_visible"), for: .normal)
       }else{
           button.setImage(UIImage(named: "ic_password_invisible"), for: .normal)
   
       }
   }
   
   func enablePasswordToggle(){
       let button = UIButton(type: .custom)
       setPasswordToggleImage(button)
       button.imageEdgeInsets = UIEdgeInsets(top: 0, left: -16, bottom: 0, right: 0)
       button.frame = CGRect(x: CGFloat(self.frame.size.width - 25), y: CGFloat(5), width: CGFloat(25), height: CGFloat(25))
       button.addTarget(self, action: #selector(self.togglePasswordView), for: .touchUpInside)
       self.rightView = button
       self.rightViewMode = .always
   }
   @IBAction func togglePasswordView(_ sender: Any) {
       self.isSecureTextEntry = !self.isSecureTextEntry
       setPasswordToggleImage(sender as! UIButton)
   }
   }
   

3. Call extension on your UITextView Outlet

    override func viewDidLoad() {
                super.viewDidLoad()
                txtPassword.enablePasswordToggle()
                txtConfirmPassword.enablePasswordToggle()
            }
