To enable a collection view to recognize focusable items diagonally in tvOS, you can utilize the layout and interaction mechanics provided by SwiftUI. In the session titled "Migrate your TVML app to SwiftUI," it is explained how to create interactive elements that respond to focus changes. By using SwiftUI's layout machinery, you can arrange items in a grid or stack that allows for diagonal navigation.
For example, you can use a LazyVGrid or LazyHGrid to arrange your items, and SwiftUI will handle the focus interactions, including diagonal movements, based on the layout you define. The focus behavior is managed by the system, which considers the spatial arrangement of items.
If you are interested in learning more about building these layouts and focus interactions, you can refer to the session Migrate your TVML app to SwiftUI (11:54) where these concepts are discussed in detail.
