Swift 2 Optionals and ToInt()

Hello guys

I'm doing the second video class of optionals and trying Amit code on my Xcode.

Currently, I'm using Xcode 7 with Swift 2 So my code are like this: 

func sendNoticeTo(aptNumber aptNumber: Int) {

}

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

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

<p>But the problem is that the (?.toInt()) doesn't work anymore on Swift2 </p> Error: 'String' does not have a member named 'ToInt'

There's a way to make this To Int conversion and it still accept nil results?

toInt() not ToInt :)
