Managed (with difficulty) to build and run, but...

[Motti-Shneor]

First, the "install" and "uninstall" targets are quite weird (they do their stuff at "build" time and not on "run" time - so on later Xcode versions, they simply fail immediately for not producing anything.

Second - you indeed said in ReadMe -

You will need to set SUDO_ASKPASS to run the installation and uninstallation targets.

but you didn't say where and to what --- I looked quite everywhere and didn't manage to find a way to make this work (I even saw your own setting somewhere in the project - assumed the value should be 'root' password and tried that too - to no avail.

So finally - only by doing both the "install" and "uninstall" stages manually in terminal (copying the .plist, the binary and then using launchctl to load the daemon) was I finally able to Mae things work. So -- this part needs some enhancement.

HOWEVER... I'm trying to use this wisdom and know-how in my own project, and simply cannot make it work.

I replicated almost exactly what you did, and my "Client" (some sample UI app I put up for this) cannot "talk" to the "XPC Service" (a global daemon I have). the lazily-initialised "connection" property always gets the "connection invalidated".

while my daemon's "listener" delegate (the one that should setup and approve a connection) simply never gets called.

Now... I wonder where I went wrong - and if there are specific "rules" you didn't write about ---

Mine is a global launch-daemon running with root privileges. its .plist is installed exactly the same place as yours, but the binary cannot reside in /Library/PrivilegedHelpers/ because it MUST be packaged within an App bundle, which is stored in /Library/xxxxx/myDaemon.app

I wonder if you can help with identifying the missing part/s so that when I get it to work - I will be able to contribute to this repo, by enhancing the documentation, or even brining in more content...

I will be more than happy to hear from you.
