Building on John Riselvato's answer, to retrieve the string back from the UIAlertView...

alert.addAction(UIAlertAction(title: "Submit", style: UIAlertAction.Style.default) { (action : UIAlertAction) in
            guard let message = alert.textFields?.first?.text else {
                return
            }
            // Text Field Response Handling Here
        })
