I get error when I set a limit to the textfield to 300

class ViewController: UIViewController, UITextFieldDelegate {

    func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {
        let newLength = count(textField.text!.utf16) + count(string.utf16) - range.length
        return newLength <= 300 // Bool
    }

}

I'm new to swift how to edit the code to fit the new 2.0 Swift – marrioa Aug 01 '15 at 18:14
`count(string.utf16)` --> `string.utf16.count`. – Martin R Aug 01 '15 at 18:43
There is an error pointed to count(textField.text!.utf16) thank you Martin R – marrioa Aug 01 '15 at 20:30
If you read *and understand* the linked-to Q&A and my previous comment then you should really be able to figure that out yourself. – Martin R Aug 01 '15 at 20:33
