The context provided from the WWDC sessions highlights various aspects of using collection views and related components in SwiftUI and UIKit.
In SwiftUI, the List and ForEach views are used to handle collections of data. The List view can be initialized with a collection of data, and it supports advanced constructions like sections. The ForEach view is used to generate views for each element in a collection, and it can be nested within other views to create complex layouts. SwiftUI also introduces APIs like ForEachSubviewOf and ForEachSectionOf to iterate over resolved subviews and sections, respectively, allowing for flexible composition of content.
In UIKit, improvements have been made to UICollectionView and UITableView with the introduction of the list environment trait. This trait helps ensure that cells are styled appropriately in any given list environment, removing the need to manually configure cell styles based on the list's appearance.
For more detailed information on these topics, you can refer to the following sessions:
