I need to communicate my app with 2 devices. A restriction is that I can’t use a server but all iOS devices will be in one Wi-Fi network. What options do I have? How I can send a message to another copy of my app running on another device?
I dont know whether its a correct approach or not but as you cannot use server,so the approach i can think of is we can create a socket connection using TCP/IP or UDP(based on reliability) for data exchange.
