I think this is true. SwiftUI became "very good" as of iOS 26 (in part because the performance gap mostly evaporated) and continues to get better in iOS 27. Over and over, I see UIKit developers trying to do things "the UIKit way" in SwiftUI, and they'd rather write TFAs instead of considering that they may need to skill up and learn to write effective and idiomatic SwiftUI.
