Do not see the option of Int? toInt() for optional chaining video

For the Optional Chaining video, he selects Int? toInt() after culprit. I do not see Int? toInt() in my options for the Xcode i'm using. I'm using the latest version.

Hello there :

As of swift 2.0 toInt() is no longer being used. Instead you can use Int().

var stringNumber = "100"
var stringNumberToInt = Int(stringNumber)

There is a new problem. I updated Xcode and now I no longer get a long list of options that displays Int(stringNumber) as well as other options. Please help thanks!
