The funny part is that Sundell and Hacking With Swift are actually among the more useful sites, offering bite sized information that you would expect Apple documentation to provide.

But Apple's documentation nowadays, is so bad (inconsistently so, some parts are fine) that these sites are filling the gap.

Further, for most other languages, Stack Overflow fits this need mostly fine. But Swift and SwiftUI have been changed so often that the accepted answer on Stack Overflow becomes outdated within a year.
