This is just an experience on using Swift in Linux to create an Epoll based server.
This is heavily based on the C Epoll server published here.
To build enter:
swift build
To run enter:
.build/debug/EpollInSwift
Then start telnet on another terminal, for example:
telnet 192.168.1.1 8080
If the connection is established successfully anything you time will be printed on the server.
