CoderKman/SwiftWebSocket: High performance WebSocket client library for Swift. · GitHub

# SwiftWebSocket

Conforming WebSocket (RFC 6455) client library implemented in pure Swift.

Test results for SwiftWebSocket. You can compare to the popular Objective-C Library

SwiftWebSocket currently passes all 521 of the Autobahn's fuzzing tests, including strict UTF-8, and message compression.

Built for Swift 2.0 - For Swift 1.2 support use the 'swift/1.2' branch.

• Swift 2.0. No need for Objective-C Bridging.
• Reads compressed messages (permessage-deflate). IETF Draft
• Strict UTF-8 processing.
• The API is modeled after the Javascript API.
• TLS / WSS support.
• binaryType property to choose between [UInt8] or NSData messages.
• Zero asserts. All networking, stream, and protocol errors are routed through the error event.
• Send pings and receive pong events.
• High performance.

##Example

func echoTest(){
    var messageNum = 0
    let ws = WebSocket("wss://echo.websocket.org")
    let send : ()->() = {
        let msg = "\(++messageNum): \(NSDate().description)"
        print("send: \(msg)")
        ws.send(msg)
    }
    ws.event.open = {
        print("opened")
        send()
    }
    ws.event.close = { code, reason, clean in
        print("close")
    }
    ws.event.error = { error in
        print("error \(error)")
    }
    ws.event.message = { message in
        if let text = message as? String {
            print("recv: \(text)")
            if messageNum == 10 {
                ws.close()
            } else {
                send()
            }
        }
    }
}
