In my project when user select specific UITextField (that UITextField supposed to get user telephone number), the QuickType Keyboard show user telephone number. I want when user select his/her telephone number I can change that (remove "+" in telephone number) and show the result in that UITextField. how can I do that?

**UPDATE**:

I tried `shouldChangeCharactersIn` (UITextFieldDelegate function) to handle that, but `replacementString` return space (" ") and if I just return true (doing nothing inside that function) to that nothing will show inside UITextField.
