NSURLSession is a fancy HTTP client. It needs to talk to an HTTP server.
None of the included iOS and OS X frameworks (that I'm aware of) include an
HTTP server.
You can either run an HTTP server on the device in your app (
https://www.google.com/search?q=ios+http+server) or you can write your own
protocol and implement it.
