Hi Carmen,

Due to swift 2, the 'count(string)' also has to change. I have made the update below, also removing the brackets which weren't required:

func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {
    let length = textField.text!.characters.count - range.length + string.characters.count

}

Oh, and your variable 'string' had a capital 'S'.

thank you Daniel Watson! =) I also did it like this func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool { let length = textField.text!.characters.count - range.length + string.characters.count }
