I'm trying to count characters on a textField but it seems that .text or utf16count does´t work anymore. Help please!

I'm trying to make a counter as in twitter but the error says: "apis deprecated as of ios 7 and earlier are unavailable in swift" I have also tried countElements( ) but nope. here is my code...

@IBAction func ContadorCaracteres(sender: AnyObject) {

    var contador = 10 - countElements(sender.text) //neither utf16count
    lblContador.text = "\(contador)"
}

It is connected to a textField because I want to count the characters as I write them and as in twitter set a counter on the bottom (with a label) but I don't know how to count the TEXT on the textField

mmm... sorry I don´t understand I´m new to this. but I saw a guy who did it like this but it gives me the same error. I want to access to the text of the textField but don't know how :

"sender.text.utf16count"
