As Scott pointed out, your check is backwards. In addition, the discussion of that initializer says that the connection is not opened until data is sent, so it doesn't really matter what it returns - it still tells you nothing about if the host is actually listening on that port. For that, you would actually need to send some data and look at the result. You are way better off dropping down to socket/connect.
