// First we need to take a look at the documentation
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
optional public func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool // return NO to not change text
- TextField: The text field containing the text.
- range: The range of characters to be replaced.
- string: The replacement string for the specified range. During typing, this parameter normally contains only the single new character that was typed, but it may contain more characters if the user is pasting text. When the user deletes one or more characters, the replacement string is empty.

//So you actualy need to combine the actual text and the new string together, not just count the character, as for example the user might be replacing a chunk of text with another using "paste" or auto correct.
//Obj-C
- (BOOL)textField:(UITextField *)textField shouldChangeCharac
