P2p network between ios devices?

Question

Objective-C

Hello. Maybe the question is of course trivial, but I did not find the information on it on the Internet in the right amount.
How to properly implement a p2p network between ios devices? It is needed to exchange files between devices.
As I understand it, each network node must be both a client and a server. There are no problems with the client. But to do in the ios application the processing of requests from other nodes on the network is still a problem. If I don't find a third-party library for this task, then I think to use CFNetwork.
If anyone has done something similar, please share your experience. And in general, I think in the right direction of thought, or I don’t think there at all. Thanks in advance!

I can advise you to study DC ++ clients for Mac, these are file exchange programs + there is a built-in chat.

A very undeveloped topic for iOS, it will be possible to transfer via the web using the principles of RTC technology, when a tunnel is created between users for data transfer, the connection is forwarded through NAT and cellular networks also function.
