My personal highlight, and probably the most useful addition for many of us: the new ContentMarginGuide! It lets us use the same margins Apple uses for its own content, like in Lists, instead of hard-coding values ourselves. Explore it here: exploreswiftui.com/library/view...

We can also read these values with GeometryReader. For example, on iPhone 18, the horizontal content margins are 16 points. On Duo in landscape, they’re 20 points on the leading edge and 0 on the trailing edge, where space is reserved on the right.

At WWDC, I told someone at Apple I’d love to have access to more of the defaults they use behind the scenes, including padding and margins. This feels like a step in the right direction, especially now that Duo is here and things are more complicated than before.
