Search the LC Lessons. I found a swipe example here:

but I remember some other lessons that also worked with both swipe and 
taps. Basically, if it isn't a swipe, you implement the tap behavior. 
There are also some lessons on 2-finger swipes in there somewhere. A 
couple that showed up in a search for "2 finger":
