Не удается найти инициализатор для типа 'UIAlertController' ОШИБКА

Question

Я немного новичок в этом, пожалуйста, помогите!

Heres полная ошибка:

Cannot find an initializer for type 'UIAlertController' that accepts an argument list of type '(title: String, message: (Int), preferredStyle: UIAlertControllerStyle)'

Вот часть моего кода, где происходит ошибка:

import UIKit 

class ViewController: UIViewController, UITextFieldDelegate, UITextViewDelegate{ 

@IBOutlet weak var CalcButton: UIButton! 
@IBOutlet weak var DaysLabel: UITextView! 
@IBOutlet weak var RateLabel: UITextView! 
@IBOutlet weak var CowsLabel: UITextView! 
@IBOutlet weak var PoundsLabel: UITextView! 

@IBOutlet weak var PoundsTextfield: UITextField! 
@IBOutlet weak var CowsTextfield: UITextField! 
@IBOutlet weak var DaysTextfield: UITextField! 
@IBOutlet weak var RateTextfield: UITextField! 
@IBOutlet weak var Label: UILabel! 

@IBAction func buttonCalc(sender: AnyObject) { 
    var Days: Int = DaysTextfield.text.toInt()! 
    var Pounds: Int = PoundsTextfield.text.toInt()! 
    var Cows: Int = CowsTextfield.text.toInt()! 
    var Rate: Int = RateTextfield.text.toInt()! 

    if Days > 0 && Pounds > 0 && Cows > 0 && Rate > 0 { 
     Label.text = String(stringInterpolationSegment: Days) 
     var sDays = String(Days) 
     var sCows = String(Cows) 
     let alertController = UIAlertController(title: "Based on the values you entered, this is what the bonus is for \(sCows) cows and \(sDays):", message: 
      (Rate/100 * Pounds) * (Cows * Days), preferredStyle: UIAlertControllerStyle.Alert) 
     alertController.addAction(UIAlertAction(title: "Dismiss", style: UIAlertActionStyle.Default,handler: nil)) 

     self.presentViewController(alertController, animated: true, completion: nil) 
    } 
} 

@IBAction func NDHIALink(sender: AnyObject) { 
    UIApplication.sharedApplication().openURL(NSURL(string: "http://www.dhia.org/")!) 
} 

Спасибо за помощь

UIAlertController(title: "Based on the values you entered, this is what the bonus is for \(sCows) cows and \(sDays):", message: 
      (Rate/100 * Pounds) * (Cows * Days), preferredStyle: UIAlertControllerStyle.Alert) 

Просто конвертировать (Rate/100 * Pounds) * (Cows * Days) в String

UIAlertController(title: "Based on the values you entered, this is what the bonus is for \(sCows) cows and \(sDays):", message: 
       String((Rate/100 * Pounds) * (Cows * Days)), preferredStyle: UIAlertControllerStyle.Alert)
