It is implemented as a UITableViewCell class category and can detect left or right horizontal swipes. Upon a left or right swipe, a swipe view is exposed. This library is meant to be flexible, so that any views can be exposed during a swipe and a myriad of actions can be taken during the swipe (e.g., swipe view animations, or cell snap back or destruction at the completion of a swipe).'
