i am trying to send data from the container app to its system extension (specifically, a camera extension. i am not entirely sure how to go about this. i read that i could utilize XPC, and i have tried this but for some reason, the system extension returns nothing when trying to connect to the XPC Service. below is an example code snipper let connectionToService = NSXPCConnection(serviceName: "example.VirtualCameraXPC")     connectionToService.remoteObjectInterface = NSXPCInterface(with:VirtualCameraXPCProtocol.self)     connectionToService.resume() //checking processes available shows that the XPC Server process is never activated also. if let proxy = connectionToService.remoteObjectProxy as? VirtualCameraXPCProtocol {       proxy.getNewString() { aString in //this is never logged.         NSLog("Second result string was: \(aString)")       }     } when i run the above code from the container app, it works properly but from the system extension, i run into the problems commented above in the code block. i would appreciate any help that will help me successfully send data from my container app to my camera extension.
