Hello, I'm developing a Mac application that uses a network extension. I'm trying to implement XPC to pass data between my main app and system extension and I'm using the SimpleFirewall demo app as a guide to do this. One thing I can't understand is how the ViewController in the SimpleFirewall main app has access to the class IPCConnection in the SimpleFirewallExtension without it being public and without SimpleFirewallExtension being imported in ViewController.
