Answer 1

In Swift 3

    let alert = UIAlertController(title: "Alert Ttitle", message: "Alert Message", preferredStyle:
        UIAlertControllerStyle.alert)

    alert.addTextField(configurationHandler: textFieldHandler)

    alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.default, handler:{ (UIAlertAction)in


    }))

    self.present(alert, animated: true, completion:nil)

func textFieldHandler(textField: UITextField!)
    {
        if (textField) != nil {
            textField.text = "Filename"
        }
    }
