I just don't get what purpose it really solves over UIKit. Everything seems far more complicated in SwiftUI, and the data dependence problems it solves did not ever really seem to be a huge issue in UIKit anyway.

Apple's sell for SwiftUI was "it's like going to a chef who knows how to cook for you" instead of "cooking yourself". But is that really a good thing? Do we really want to be taking less control of our applications when we write them?

The worst part is all these tutorials that have to combine SwiftUI and UIKit because the former is very buggy in certain cases, like navigation trees on iOS have really janky animations using SwiftUI. So you have to coordinate all your Views using UIKit. It just seems barely easier to use SwiftUI most of the time.

EDIT: Basically, in summary, it seems like a very complicated (look at the crazy language features they had to add for it) plus very opaque ("it magically does it for you just how you wanted") way to write the same apps you were already writing fine in UIKit and AppKit
