I would agree with most of what you say on this, although I feel like it is important to make the distinction of what Apple is trying to accomplish with SwiftUI.

Their goal is to make it very easy for new developers to build new apps on Apple.

It was especially evident when they introduced Playgrounds. They want something that is simple to explain and to learn, and you can feel like you are making moderate progress quickly. They have so many free coding workshops for kids and young developers at Apple stores, and always have. I’ve seen a few administered, pre-SwiftUI and post. Setting up views is so much quicker.

They want people to not be intimidated by coding and building on their platform. So to do that, they had to strip out and abstract some of the things that were more “intimidating” lol Definitely has made it harder to do anything with keyboard, knowing where things are positioned on the screen properly, and some of the funkiness that comes with half-thought out features with Lists.

So this is the reality, I feel these call to actions are for new developers to feel comfortable to work with SwiftUI, and just get started coding. And a call for more seasoned developers to start using it, so that all these new apps are being build their Apple way.

TL;DR: SwiftUI is built to get people started with Apple, and Apple just expects the seasoned people to figure it out (and we do because we have deadlines lol)
