What's incredibly annoying is that a lot of the SwiftUI components are just wrappers around the equivalent UIKit components (eg. ScrollView/UIScrollView), but are missing a lot of the functionality of the underlying components.
These should really be open source: it's such a waste of time to have to experimentally poke around to see how the SwiftUI components interact with their UIKit counterparts, when these should really just be straightforward wrappers.
In many cases, the declarative APIs are just poorly thought out and/or clearly not "battle tested", and there is a lot of API churn in really crucial components which are also often not backported to older OS versions.
