The "foreach" concept in SwiftUI is discussed in the session titled "Demystify SwiftUI containers" (Session ID: wwdc2024-10146). The session explains how the ForEach view is used to generate a collection of views from data. It highlights the difference between declared subviews and resolved subviews, emphasizing that ForEach is a declared subview that produces resolved subviews when the app is running.
The session also introduces new APIs like foreach subview of, which iterates over resolved subviews, and foreach section of, which iterates over sections within a view. These APIs allow for more flexible composition and organization of content in SwiftUI.
For more detailed information, you can refer to the session Demystify SwiftUI containers (06:03) where the ForEach view and its functionalities are discussed.
