Using `textField:shouldChangeCharactersInRange:`, how do I get the text including the current typed character?

Question

I\'m using the code below to try and have textField2\'s text content get updated to match textField1\'s whenever the user types in textField1

Answer 1

Swift version for it :

func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {

    if string == " " {
        return false
    }

    let userEnteredString = textField.text

    var newString = (userEnteredString! as NSString).stringByReplacingCharactersInRange(range, withString: string) as NSString

    print(newString)

    return true
}
