Yes, I mentioned that. There’s probably a better example but this is off the top of my head as something I experienced myself. My point is that the blog post suggests the Swift native version then discusses NSMapTable without ever calling out the fact that you can’t use the latter cross-platform. I find that endemic in the Swift community, there’s a base assumption you’re coding on an Apple platform (and often specifically on iOS!), it adds an additional barrier to getting things done.

And that article is from 2020. A lot has changed since.
