Can't recommend anything specific, to be honest. I've been piecing together information from old Apple docs, StackOverflow, API header files, and a bunch of really weird blogs. A lot of trial and error as well.
I think your best bet is ChatGPT. It has seen every possible use-case of Apple APIs from GitHub so it should know a lot. I've gotten some good tips from it for very specific things that did not exist on the web.
Whilst I'm just a web developer, I've had times, even using third party libraries that aren't particularly well documented, where ChatGPT seems to have a shockingly good grasp of the library and seems to understand it better than the documentation does.
