UICollectionView is a powerful and flexible component in UIKit that allows developers to create complex and highly customizable layouts for displaying a collection of data. It is often used for creating grid-like layouts, but it can be adapted for various other layouts as well.
In the context of WWDC, the session titled "What’s new in UIKit" discusses improvements related to UICollectionView. Specifically, it mentions that UI collection view list sections now have the list environment trait set, which helps ensure that cells are styled appropriately in any given list. This new trait allows UI list content configuration and UI background configuration to adjust their properties to match the list environment, removing the need to know the style of the list when configuring a cell. This makes it easier to manage the appearance of cells in different contexts, such as in the Files app, which uses a UI collection view with compositional layout to display lists in different styles depending on the orientation.
For more details, you can refer to the session What’s new in UIKit (07:44).
