Socket.io-client-swift: Unable to connect to socket

[Ketan-Wadyalkar]

       let manager = SocketManager(socketURL: URL(string: "http://xxx.xxx.x.x:5000")!, config: [.log(true)])

    socket = manager.defaultSocket

   // Below method is never called.
         socket.on(clientEvent: .connect) {data, ack in
             print("socket connected")
        }

    socket.on(clientEvent: .error) {data, ack in
        print("socket error")
    }

    socket.connect()

    socket.onAny {
        print("Got event: \($0.event), with items: \(String(describing: $0.items))")
    }

I am missing on something in my code ?
How to check if socket was connected successfully or there was an error ?
Socket server is in an android app.
Socket never gets connected from my iOS app.

Below is the debug log

@Ketan-Wadyalkar Please read the FAQ and a little on ARC; the manager is being released from memory as soon as it goes out of scope.

@nuclearace Thanks for quick response and My bad that i didn't checked FAQ before raising this issue.
I have updated my code and it's working fine for web-socket but i am facing the above mentioned issue when i try to connect to the socket created by android app.
There is no issue in the socket, i am able to connect the socket using android app & Starscream library for iOS.
Any suggestion on how to do this using socket.io ?
Also it would be really helpful if you can guide me on how to write jsonstring on socket.

Thanks in advance.
