Estou tentando usar a estrutura XMPP (https://github.com/robbiehanson/XMPPFramework) usando swift. Eu sou novo em veloz

    class ViewController: UIViewController {
    var password: NSString?
    var isOpen: Bool = false
    var xstream: XMPPStream?

    var loginServer: String = ""
    override func viewDidLoad() {
        super.viewDidLoad()
        println(connect())
        // Do any additional setup after loading the view, typically from a nib.
    }
        override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func connect() ->Bool{


        var xstream = XMPPStream()
        var error: NSError?
        xstream.addDelegate(self, delegateQueue: dispatch_get_main_queue())

        xstream.myJID = XMPPJID.jidWithString("test@localhost")
        xstream.hostName="127.0.0.1"
        xstream.hostPort=5222
        var password = "testing"

        if !xstream.connectWithTimeout(XMPPStreamTimeoutNone, error: &error) {
          println(error)

        }
        println(xstream.isConnecting()) // This prints true
        return xstream.isConnected();// This prints false.
    }
}

O nome de usuário e a senha e os detalhes do servidor estão corretos porque eu uso o adium para conectar ao servidor e funciona bem.
