There's the NSWorkspaceSessionDidBecomeActiveNotification et al, but that doesn't say who the current user is. Is there a way to find out that? (I mean, I could have a LaunchAgent that send "I've become active!" log message or something, and then use the most recent one. Is there another way?)

On three different machines (all running Xcode 13 and Big Sur), it always tells me that the command-line developer tools need to be installed. I've "installed" them four times so far on one machine, and at least twice on the other two.

I wrote a very dumb transparent proxy. The extension simply sends data to a daemon, and that daemon sends network data back to the proxy. It worked with small test connections, and I was fairly pleased. Then I tried transferring a ~4mbyte file (using curl), and it got a way in, and then the daemon did a network read of something like 400kbytes, and went to send that to the extension, and the flow.write method never called the completion handler. If I limit the read size to 64k max, it works. The most frustrating thing is I don't see any logging information related to it, so I can only guess what's going on. Any ideas, thoughts, or clear stupidities on my part?

My project got more complicated, and I had to integrate in some C++ code. In the process, I ended up with a couple of targets, which had some shared ObjC++ and Swift code. Normally, if it's all the same language, I just put the files in question into each of the targets, and we're all happy. But with having both ObjC++ and Swift, I had to deal with the bridging headers. Which got created as ${PRODUCT_NAME}-Swift.h, which made it very difficult for that file to be included in a .mm file used in multiple targets. I tried googling, and forum-searching, and couldn't quite figure out how to make it generate a single header file. Instead, I added a new target, a static library using the common files. I added a Run Script phase which copied *-Swift.h from the Derived Sources directory to the build directory. Then I added the library as a dependency for each of the other targets, and of course linked with it. This seems to work, even after doing a rm -rf build and building everything again. So... was this the (or at least, a) right way to do this? Are there better practices I should be using? Merci beaucou, je suis tres stupid quelquefois.
