is it intentional that the bundle ID has the Team ID appended, while launchctl list is asked to look for something with the Team ID prepended?

Quinn, thank you for the hint. I was filtering the Console output on my app name, the culprit was fingered by sysextd a few lines further up when I turned off that filter - I didn't prefix my Mach service name with the name of the app group in my entitlement. For future reference, the error 9 is listed in SystemExtension/SystemExtensions.h, and the term to search the SDK for is "OSSystemExtensionErrorDomain"

Paul Hudson's Swift on Sundays series on YouTube has this - https://www.youtube.com/watch?v=TJfh8wXbfEw A functioning game in an hour and a bit, and 160 lines of code.

2 days ago there was an outage of the notarization service, and a performance problem which persisted a few hours beyond the outage. You can visit https://developer.apple.com/system-status/ if things are taking a suspiciously long time, that's how I know.

I think the next step beyond "learning coding" is learning to apply that knowledge to a particular domain. Code does something, usually something useful to yourself or other people. What useful thing would you like to make possible? What would you like to learn, and how does being able to code help you with that goal?

are you sure you're leaking memory created by the call to IOCreatePlugInInterface? It creates an interface, as its name suggests, returned in pHandle. Are you releasing that interface when you're done with it?

what do you mean by "does not work"? your code doesn't compile, primarily because UIKit is not available on macOS (AppKit is, so your UIViews should be NSViews). Even so, in setupCamera you refer to a variable called 'view' which is not declared.

You're better off asking such non-developer questions on a customer support forum. Are you trying to share a WiFi connection over WiFi? You can't do that.

I entered your code and ran it. Byte doesn't stop walking because Byte isn't done. There's a little scoreboard at the top left of the scene - it shows Bytes has collected 1/1 gems and tripped 0/1 switches. Try to split your code into functions which do only one thing, and are well named. For instance, rename 'checker' to 'checkSwitch' and have it only change the switch state if necessary, rather than sometimes changes switch state, and sometimes move forward. In this exercise, the path is predictable (you can see it), so your steps can be a list of instructions, with no branches and no conditionals.

I think you should start by reading this post https://developer.apple.com/forums/thread/39204

from AudioToolbox/AudioUnitParameters.h, CF_ENUM(AudioUnitParameterID) { // Global, LinearGain, 0->1, 1 kHALOutputParam_Volume = 14  }; AudioUnitSetParameter is declared in AudioToolbox/AUComponent.h, here you will also find: typedef Float32 AudioUnitParameterValue;

there's a little popup in the bottom left of the panel with the variables in it (it is not visible in your screenshot). Try setting it to "all" instead of "auto" or "local".

I suggest you start here: https://opensource.com/article/19/5/python-3-default-mac#what-to-do the basic advice is "install pyenv", then use pyenv-virtualenv.

Your description isn't quite clear, but it sounds like you are getting some portion of the complete frame. Try this - in setupCamera, use your own serial queue, rather than the main queue. There's an example here: https://developer.apple.com/documentation/vision/tracking_the_user_s_face_in_real_time/ hth, Stuart
