It’s a seductive idea, but it displaces who is responsible for the poor framework development onto users of the framework.

It’s easy to say they were just trying to be trendy and thus the real flaw was the trend is bad and the fault of worse devs than us (the young web devs mentioned)

The thing that obviates that is the trendy stuff works, yet, SwiftUI doesn’t.

(source: I wrote ObjC/Cocoa as early as 2006, and switched to Flutter as my primary dev kit some years ago: it simply doesn’t have the performance issues mentioned.)
