Send multiple data

I am working on a turn based Game Center game and want to convert a string and an Int to NSData and send it to the other player.

This is how i convert the string:

      let sendString = "Hello"
       let data = sendString.dataUsingEncoding(NSUTF8StringEncoding,   allowLossyConversion: true)

This is how i convert the int:

      let sendInt = 2
       let data = NSData(bytes: [sendInt], length: sizeof(Int))

This work, but how do i send both instances? I only manage to send one of them.

Not sure the context you are working in, but if it's a func or a struct and you want to return two things the easiest way is usually to return a tuple.
