A highly incomplete chat app written in Swift using Network.framework & Streams (client-side) and Swift NIO (server-side)
No 3-rd party libs used, this is a prototype of how chat funtionality is implemented using stream sockets.

1. Clone/download repo

2. Fetch dependencies and generate project:
   cd .../{project directory}/NIOServer
   $ swift package generate-xcodeproj
   

3. Run server
   $ cd .../{project directory}/NIOServer/Sources
   $ open TCPServer.xcodeproj
   build and run ('command + R' or from terminal: ‘$ swift run TCPServer’)
   

Note: in case you want to kill the process blocking your port:
$ lsof -t -i tcp: | xargs kill (or '$ sudo lsof -t -i tcp: | xargs kill')

4. Run client:
   $ cd .../{project directory}/Client
   $ open NetworkFrameworkResearch.xcodeproj
   command + R, fill host/port of the server
   

Run multiple simulators (ex. 7, 7Plus, 8)

Profit!
