Based on the experience with PlexConnect (forum, github) this App was created as a proof-of-concept of an Apple TV 4 Plex client. And to have a look into Swift and the surrounding habitat...
It is based on PlexConnect's well-known XMLConverter concept, rethought and rewritten in Apple's Swift language.

Basically, you can do with the code whatever you want - with one constraint: Don't push binaries from this software, if essentially unmodified, to the Apple AppStore.
