The article matches my experience with SwiftUI [1][2]. For example, AFAICT, it's not really possible to write a usable node-graph editor using SwiftUI due to layout and dependency analysis overhead. You have to put the entire node graph inside a Canvas and do your own event handling, which is what we did in [3].

UIKit and AppKit aren't slow though, and Apple has every incentive to make this faster (they wrote SwiftUI's dependency graph in C++ after all, so they do seem to care), which makes me think there is just inherent slowness from the dependency analysis that is required for these sorts of systems (that seems to be what I see on the profiles).
