ytSwift is cool new (well a few months old now) concept that allows users to instant-search, simultaneously watch, quickly pull videos from a particular user, easily share, and retrieve all metadata for youtube videos. The goal for creating ytSwift was to keep the entire youtube experience limited to a single page, allowing users to do most of what they do without having to open new tabs, hit the back button, or browse through numerous pages to watch the videos they want to.
