NSXPCListener

A listener that waits for new incoming connections, configures them, and accepts or rejects them.

Declaration

class NSXPCListener

Overview

Each XPC service, launchd agent, or launchd daemon typically has at least one NSXPCListener object that listens for connections to a specified service name. Each listener must have a delegate that conforms to the NSXPCListenerDelegate protocol. When the listener receives a new connection request, it creates a new NSXPCConnection object, then asks the delegate to inspect, configure, and resume the connection object by calling the delegate’s listener(_:shouldAcceptNewConnection:) method.
