Hello!

I can't found any example about that in the Apple documentation. But I would like to write a SIMPLE, VERY SIMPLE client/server Asynchronous program.

Server part: a window with a Edit Text

Client part: a Edit Text and a Button

The server part must wait the connection from the client, when I launch the client, I insert a simple text (for example "hello") in the textbox, and when I press the button the data is sent to the server part and show it in the Edit Text.

I think is a good example for who want to start a develop something like that....or where I'm wrong???

There really is no such thing as a simple network program. For example, your problem description completely ignores security, which isn’t something that you can reasonably do in the modern world. If you’re new to networking I recommend that you watch my WWDC 2010 presentation, Network Apps for iPhone OS, which is a good introduction to the overall topic.

If you’re just getting start a good place to look is the WiTap sample code. This shows how to set up a TCP listener on the local network, connect to that listener, and exchange messages. It’s in Objective-C, but all of the APIs it uses are easy enough to call from Swift.
