I've been learning SwiftUI for MacOS to explore the plausibility of a particular idea I had, and I do think there's some truth in this. So far, I've found it best to seek out more robust, somewhat complete examples that use a particular API in a more realistic context, as well as many other discrete tidbits of information wherever they may be found. In this case, that's the hackingwithswift blog posts, the hackingwithswift youtube tutorials that follow the blog posts, swiftbysundell, and a number of other independent developers that have fairly lengthy but digestible detailed tutorials on specific APIs; using all of it feels a little like the process of getting a fingerprint registered on a new phone, where you get decent coverage and breadth quickly but then fill in the gaps. However, I don't think this is unique to WWDC or swift or iOS, it's just that those platforms typically demand only the newest versions of iOS or macOS or even unreleased hardware to get much value out of them, so I can't imagine you'd be implementing them any time shortly-thereafter.
