Introduction

Welcome to the documentation for Sockit, a powerful framework for socket programming in Swift. Whether you are building real-time chat applications, multiplayer games, or any other type of networked application, Sockit provides you with the tools and abstractions to easily handle socket communication.

Getting Started

In order to use Sockit in your Swift projects, follow the steps below:

  1. Install Sockit via Cocoapods or Carthage
  2. Import the Sockit module in your project
  3. Create a socket and configure it based on your requirements
  4. Handle socket events using Sockit’s event-driven architecture
  5. Send and receive data through the socket
  6. Handle errors and gracefully close the socket connection when necessary

Installation

You can install Sockit using either Cocoapods or Carthage.

Cocoapods

To install Sockit via Cocoapods, add the following line to your project’s Podfile:

pod 'Sockit'

Then, run the command pod install to install the dependency.

Carthage

To install Sockit via Carthage, add the following line to your Cartfile:

github "sockit/sockit"

Then, run the command carthage update to fetch and build the dependency. Finally, add the generated framework to your Xcode project.

Usage

Once you have successfully installed Sockit, you can start using it in your Swift project.

Importing Sockit

To import the Sockit module, add the following line to your Swift file:

import Sockit

Creating a Socket

To create a socket, use the provided Socket class. Here’s an example of creating a TCP socket:

// Create a TCP socket
let socket = Socket(type: .tcp)

Configuring a Socket

After creating a socket, you can configure it based on your requirements. For example, you can set the host and port to connect to:

// Set the host and port
socket.host = "example.com"
socket.port = 8080

Handling Socket Events

Sockit follows an event-driven architecture, allowing you to handle socket events easily. Register your event handlers to receive notifications about various socket events such as connection, disconnection, and data reception.

// Register event handler for connection
socket.onConnect = {
    print("Socket connected")
}

// Register event handler for disconnection
socket.onDisconnect = { error in
    print("Socket disconnected with error: \(error)")
}

// Register event handler for receiving data
socket.onData = { data in
    print("Received data: \(data)")
}

Sending and Receiving Data

You can use the methods provided by the Socket class to send and receive data through the socket. The example below shows how to send data as well as receive data:

// Send data
socket.send(data: "Hello, server!")

// Receive data
socket.onData = { data in
    print("Received data: \(data)")
}

Handling Errors

Sockit handles errors gracefully and provides you with the necessary information to handle errors effectively. When receiving an error from the socket, the onDisconnect event handler will be triggered with the error as a parameter.

// Register event handler for disconnection
socket.onDisconnect = { error in
    print("Socket disconnected with error: \(error)")
}

Closing a Socket

To gracefully close a socket connection, use the close() method:

// Close the socket
socket.close()

Conclusion

Congratulations! You now have a solid understanding of how to use Sockit in your Swift projects. Refer to the official documentation for more advanced features and examples. Happy coding!
