The title of the session was “Background execution demystified”
Background execution is a computer science topic that many don’t understand well. Much like font antialiasing or other computer science topics that people don’t have to deal with daily.
Note: I’m not saying Apple APIs are great. I was just originally pointing out the context of your post.
I spent an afternoon watching and re-watching this video just to figure out how the otherwise-undocumented behaviors of the API work. It was exclusively about Apple's implementation, and not in any way about the general CS topic.
