Noted, but just want to reiterate that some of these topics are complex and many are worthy of articles (or even books) of their own. (Especially the brief map/append and struct/class recommendations.)

This is another in what seems to be a "top 5" series, and another where the implied recommendations tend to be taken by readers at face value, and as such without the nuance that might come from a deeper evaluation of the subject.

Room for a lot of different styles, of course, but it would be interesting to see what you could come up with if you dug deep into an aspect of Swift and SwiftUI like fatbobman or Jacob.
