flashing (flickering) occurs when canceling animation (returning to current view controller),
something like showing next view controller for milliseconds - and then hide it

How it can be prevented?

How can gesture for going to next view controller be initialized without waiting for [finishInteractiveTransition] end (to mimic the functionality of UIPageViewController changing child items)

It seems that completionCurve in ignored in the current implementation (it always seems to uses a linear curve when completing the transition animation). It'd be nice if we could use the easy in out curve for completion (while keeping the linear one when interacting with the transition).

Since the animation controller is unaware of being wrapped in AWPercentDrivenInteractiveTransition, it will always call completeTransition:YES to its transition context, even when the transition is cancelled and the animation is reversed. This can cause issues in certain contexts.

Potential solutions

• Swizzle completeTransition: on the context and catch up when called by the animator. Of course, swizzle back to original implementation once transition is over.
• Make AWPercentDrivenInteractiveTransition call completeTransition:NO itself. It would be run several times though :/

I ported the project to Swift here. I am about to integrate it into my project, and start testing.

Since I thought it doesn't make sense to have two implementations, I decided to remove the ObjC stuff. I suggest, if you like, to merge this into a new branch.
