you are looking at GKSession.. and this is an excellent and comprehensive tutorial for what you're looking for. IF you wanna dive a little deeper take a look at this project I made.

the link in the comment above uses bonjour, which is a layer below GKSession (ie GKSession is a wrapper for bonjour).. so depending on how many devices you want to connect at a time (GKSession starts choking around 3-4) and how extensive your throughput/ping requirements are, you'd chose one or the other.

Answer 3

Take a look at the Game Kit class. Game Kit provides classes that implement the low-level networking infrastructure to allow the devices to exchange data in real time.
