In Swift collectionView:canMoveItemAtIndexPath: doesn't accept nil index path.

Thanks. Unfortunately, we had the exact same naming as iOS 9's collection view data source. The best way to work around this is to namespace the API as provided at #101 but I haven't figure out an upgrade path for users of this library so I'm not too sure yet.

Either way, I'm hoping people was able to support iOS 9 at minimum soon so they can use the official API.
