It looks like your carousel isn't centered which makes me think that maybe its bounds are wrong.
iCarousel doesn't have clipsToBounds enabled by default, which means that if the bounds are wrong, you will still see your item views, but may not be able to interact with them.
Try enabling clipsToBounds on the carousel, and setting the backgroundColor to something like red, so you can see if the carousel dimensions are correct.
If they aren't you may need to adjust your autoresizing or autolayout constraints.
UPDATE:
This was actually a bug in iCarousel relating to the heuristic it uses to determine if swipe gestures should be intercepted by the carousel. Fixed in beta 7.
