In this session, we will build a Jabber Client for iOS. The application developed in this session will enable users to sign in, add buddies, and send messages. In the process of building this app, we will describe how to install and configure a jabber server, create accounts, and interact with the server from an iOS application. To simulate a chat environment we will build a scenario with two users: one user will be chatting from an iPhone app and the other will be using iChat.
