Not able to reproduce in my case, Check if there is any code in viewwillappear which is making textbox empty or applicationdidenterforeground. — Awesome.Apple, Mar 11 '16 at 05:54

Not able to reproduce either. Maybe you can create a breakpoint and run your app in debug mode to retry. — xi.lin, Mar 11 '16 at 06:12

You can override this method in your custom responders to update your object's state or perform some action such as highlighting the selection. If you override this method, you must call super at some point in your implementation.

The custom Class should be similar to:

class CustomSecureTextField: UITextField { 
    override func becomeFirstResponder() -> Bool {
        super.becomeFirstResponder()
         //if !isSecureTextEntry {
         //  return true 
         //} 
         if let currentText = text {  
             insertText(currentText)
         } 
         return true
    } 
}
