How to convert from String to Int in code 8

Hello, I am using Xcode 8 and I understand that these tutorials use an earlier version.

The .toInt() function no longer works as described in the video. What are my other options for achieving this? Below is what I have so far.

import UIKit

func findApt (aptNumber:String) -> String? { let aptNumbers = ["101", "202", "303", "404"] for tempAptNumber in aptNumbers { if tempAptNumber == aptNumber { return aptNumber } } return nil }

func sendNoticeTo (aptNumber:Int) {

}

if let culprit = findApt(aptNumber:"101") { sendNoticeTo(aptNumber: culprit) }

var stringNumber = "1234"
var numberFromString = Int(stringNumber)
