Error compiling getting-started tutorial in Xcode 6.2

I’ve been following the EstiCafe getting started tutorial:

and when I try to compile in Xcode 6.2 I get the error

"Expression resolves to an unused function" 

on line 36 of MenuViewController.swift.

    presentViewController(vc, animated: true) {

I’m assuming this is an xcode/swift version compatibility issue. Does anyone know how I should modify this line to make it compile?

Ok must have been user error as it is now compiling.
