The article you cited is from 2022 and so is irrelevant, since SwiftUI's performance profile completely changed as of xOS 26.
Claims like "It's hard to build a performant SwiftUI app" get into skill-issue territory, but more importantly, the reality is there are only "SwiftUI-first apps". All non-trivial SwiftUI-first apps will also use UIKit/AppKit as needed, typically for capabilties that aren't yet available via SwiftUI.
