Socket.IO-Client-Swift
======================

Socket.IO-client for Swift. Supports ws/wss connections and binary

Installation
============
1. Requires linking [SocketRocket](https://github.com/square/SocketRocket) against your xcode project. (Be sure to link the [frameworks](https://github.com/square/SocketRocket#framework-dependencies) required by SocketRocket)
2. Create a bridging header for SocketRocket
3. Copy the SwiftIO folder into your xcode project

Use
===

```swift
// opts can be omitted, will use default values
let socket = SocketIOClient(socketURL: "https://localhost:8080", opts: [
    "reconnects": true, // default true
    "reconnectAttempts": 5, // default -1 (infinite tries)
    "reconnectWait": 5 // default 10
])
