You should try the last few Xcode versions some time. As far as I'm aware there's not a single line of Javascript in it, and all UI is 'native' (whatever that means these days), and the whole experience is such a janky and laggy mess that even VSCode feels slick.

It's trivial to write slow UI application in any tech stack, and just being 'native' really means nothing nowadays.
