From real device cannot able to send bytes

[muga87]

Hi, i need to send array of bytes to server. I have tried from simulator I can able to send and getting response.
to establish connection cam using
client = TCPClient(address: myhost, port: myport) (in viewDidLoad)
Same thing when I tried to send from iPhone device, connection is success but can not able to send bytes. I am getting following error.

Error in data sent : "The operation couldn’t be completed. (SwiftSocket.SocketError error 3.)"

am I need to do anything configuration in device?
