    I finally reached a stage, where I think I need something new to go on in my programming life. I decided to make an application that takes advantages of simple networking features of OS X.

    A simple application I want to make is an IRC Client, or at least a simple chat program that can send messages between 2 different computers. That is an example of the type of a networking program

    But I am really stuck. How do I begin? What technologies I need to know? I am fairly proficient in C++, and have great experience with Cocoa and ObjC. Any recommendations, or technologies I will need to take a look at?

    Look into socket programming.


    Here is the RFC of the IRC specification which you will need to know.

    There are several good Cocoa classes for networking. Check out SocketClasses on CocoaDev. I'd suggest AsyncSocket.

    I started a simple IRC API in Objective-C; its still not quite halfway done. I'm not using the Cocoa framework as I want to keep it platform independent. Eventually when I finish the API a bot will soon follow. Text parsing in C stinks.. heh

    Anyway, I'm just using sockets in C with TCP then wrapped up in nice classes in Objective-C. Eventually I will add support for more than one connection, but gotta get the parsing properly working first :/

    You might check out Xchat-aqua, its open source... http://sourceforge.net/projects/xchataqua/
    And don't forget the IRC protocol: http://www.irchelp.org/irchelp/rfc/rfc.html

    I'm almost ashamed to show my code (lol); still has much that needs to be done, but https://launchpad.net/libobirc if you really want to glance.

    Thank you all for your answers. I considered taking a look into X-Chat, but I wasn't sure if that used the method I am willing to use. I think that simple BSD sockets will be fine for me. I will stick at that atm, till I need more.
