Thanks for your valuable feedback Quinn. I have a follow up question.  

Is it possible to give a provision such that only intended Clients can connect to my Server and not every independent process who knows the service name that is advertised in launchd.plist ? 

Concept is basically to make sure the Clients that try to connect to my Server adhere to a protocol while connecting to my Server and if a Client doesn't then I would discard that connection. 

thanks,
~Arjun

Yes.  It's perfectly valid to create a launchd daemon or agent that vends an XPC service via the MachServices property of its launchd property list file.

Yes.  If you vend your service from a launchd agent, it'll only be available to clients in a particular login context.  If you make it a launchd daemon, it'll be available to all clients (subject to sandboxing restrictions).  In the latter case the clients will have to set XPC_CONNECTION_MACH_SERVICE_PRIVILEGED.

Share and Enjoy
