NSWorkspace runningApplications doesn't return my XPC mach service

问题

NSArray *activeApps = [[NSWorkspace sharedWorkspace] runningApplications];

Returns running applications and agents, but i cannot see my running XPC mach service (although it is running and visible in activity monitor processes)

even when i look up the PID in activity monitor

id res = [NSRunningApplication runningApplicationWithProcessIdentifier:223];

i get res nil, although with other processes this works well

回答1:

The NSRunningApplication documentation states:

Only user applications are tracked; this does not provide information about every process on the system

What exactly you trying to accomplish? you dont need to check for a service in this way.
