P.167 Error when trying to set indexPath

I am getting an error when I try to set the indexPath as the book describes.
I tried to look up NSIndexSet in the documentation but I could not find a method like it describes in the book. Perhaps the syntax changed in Swift 3.0? I am not sure…

Sorry I made a typo, the method suppose to be NSIndexPath(…)
I fixed the issue and it works! I am so happy.

By the way here is some updated syntax in the line below.
