I believe so. The launchd plist is:
==
"http://www.apple.com/DTDs/PropertyList-1.0.dtd;>
Label
org.sil.KLMHelper
MachServices
org.sil.KLMHelper
Program
/Library/PrivilegedHelperTools/org.sil.KLMHelper
ProgramArguments
/Library/PrivilegedHelperTools/org.sil.KLMHelper
==
The code to connect to the helper is:
==
helperToolConnection =
NSXPCConnection.init(machServiceName: toolIdentifier, options:
NSXPCConnection.Options.privileged)
helperToolConnection?.remoteObjectInterface =
NSXPCInterface.init(with: Keyboard_Layout_HelperProtocol.self)
helperToolConnection?.invalidationHandler = {
self.helperToolConnection?.invalidationHandler = nil
OperationQueue.main.addOperation({
self.helperToolConnection = nil
})
}
==
where toolIdentifier is "org.sil.KLMHelper"
The code that invokes the code is like this:
==
let connection = connectionManager.helperToolConnection
let proxy =
connection?.remoteObjectProxyWithErrorHandler { (error) in
NSApp.presentError(error)
} as! Keyboard_Layout_HelperProtocol
let authorization = connectionManager.authorization
// Call the proxy with the appropriate code
proxy.authenticatedCreateDirectory(url: location,
authorization: authorization) { handler($0, $1) }
==
All of this is derived from Even Better Authorization Sample, translated
to Swift.

Are you specifying the MachService you use for your XPC connection in your launchd job?

Debugging a privileged helper
I have a working app in Objective-C that has a privileged helper. I am creating a different app, this time in Swift, and need a privileged helper. As far as I can tell, I have mirrored all the appropriate settings, but it's not working. Calling SMJobBless succeeds, and the job is installed appropriately in /Library/LaunchDaemons and /Library/PrivilegedHelperTools. However, when I try to activate it via NSXPCConnection, all appears to be fine in the host app, but the helper tool never launches, as far as I can tell. I've run out of places to look for problems, so I need some more ideas on how to track down the problem. Any suggestions?
