That is what I'm talking about: SwiftUI automatically uses the recommended conventions for spacing, padding, etc. which are different for macOS vs. iOS etc., and it also takes user environment settings into account, like font sizes and other accessibility options.
Unfortunately swift doesn't have a meaningful windows story, and giving up on 100s of millions of users is less than ideal for most "crossplatform" contexts. :/
So even if Apple doesn't want to port SwiftUI, maybe other people could.
