Except that doesn't scale for different devices, and will look ridiculous on the Mac when the user resizes the window. Non-Apple programmers are probably shocked to learn that to this day there's still no graceful way to scale an Apple UI up. You can't just set "scale symmetrically" on a view. It comes down to positioning things with multiplication factors and literally trying and retrying those decimal numbers on every goddamned control/label combo. Over and over and over... Then we needed to build a cross-platform desktop app, and went with Qt and QML. I expected to dislike QML, but no; it's really nice to work with, and our app looks great. QML has been around for years, so it's disappointing that SwiftUI has turned out to be such an apparent fiasco.
