I think a big part of this in recent years is SwiftUI just not being fully-cooked and Apple trying to shove it into a bunch of areas without enough attention to performance. Not sure how it is on iOS, but for example, the Settings app feels chuuuunky if you navigate through the panes with up and down arrow keys. I wasn't able to make a selectable list view that worked consistently and didn't feel like a regression compared to an equivalent AppKit view

FWIW, SwiftUI got a huge performance boost for iOS/macOS 26+, and Instruments 26 has been nice for finding performance bottlenecks. You may find the SwiftUI performance auditor in a free/FOSS project of mine (https://charleswiltgen.github.io/Axiom/commands/ui-design/au...) helpful as well.
Why it took 4 years to get to near-UIKit levels of performance I couldnt say, but I've had a great experience working with it on an app that's 97% SwiftUI.
