What’s the old and new way of creating collections vies?

The old way of creating collection views in SwiftUI involved using a list initializer with a collection parameter, which is essentially a convenience for creating a ForEach view. This method generates views for each element in a collection and provides those to its container. This approach allows for creating more advanced constructions, such as multiple collections of data organized into sections.

The new way, as discussed in the session "Demystify SwiftUI containers," involves using a more flexible composition approach. Instead of being limited to a single collection of data, you can now initialize containers using a ViewBuilder. This allows for combining different kinds of content together. For example, you can define some rows statically and others dynamically within the same list. The new API ForEachSubview allows you to transform each subview into a different kind of view, providing more flexibility in how you compose your UI.

For more details, you can refer to the session Demystify SwiftUI containers (03:03).
