Apart from the starter project that you have to download, you must also grab another file from here.For now just get the file, and you’ll see next how to use it.First of all, the app will be parted by two view controllers: In the first one, the user will be able to “sign in” to the app by providing a nickname only (we’ll avoid a more complicated login mechanism for obvious reasons).Once that happens, all existing users will be listed in a tableview, where next to their names a connection status indication will be displayed ( The second view controller is dedicated to the chat functionality.IO library (client) for i OS and how to achieve real-time communication with a server, I decided that our best hit would be to create a chat application as the demo app of this tutorial.Of course, we won’t make everything from scratch, as the point is to focus on the important details only.Once that happens, all the connected apps can send messages to that port (outgoing messages), and listen to it for any incoming messages.

Even though we’ll see everything in details in the following parts, let me give you a short brief of our goal here.

The websocket communication relies on the client-server logic, where a persistent connection between a server and a client always exists.

To be more precise, the server “opens” a dedicated port where clients get connected to it.

Implementing the connection to a socket and communicating through it with a server is not the easiest task on the world. IO in a big project recently, and I had the chance to see how easy it actually is to have bidirectional communication with the server, and get messages instantly to the app.

Even though the whole idea sounds fascinating, there might exist several problems until it’s possible to achieve a proper communication. I strongly advice you to pay a visit to the official website, so you understand what is all about and how it works. IO has been designed mostly for web applications, it offers a library for i OS that can be integrated into a project in no-time at all.
