This post is from the Activity iPhone Duo SwiftUI Q&A.
Is ArrangementView intended specifically for iPhone Duo, or should it also be used for adaptive layouts across iPhone and iPad?
This is unclear because when I use a horizontally or vertically split ArrangementView on a non-Duo device, such as iPad, it only displays one of its child views.
If ArrangementView is Duo-specific, what is the recommended way to use it only on iPhone Duo while falling back to a different layout on other devices? I haven’t seen an API or pattern for conditionally switching between those layouts.
