what can I use to display a tree data structrue

To display a tree data structure in SwiftUI, you can use the ForEach view to iterate over your data and create a hierarchical view. The session "Demystify SwiftUI containers" from WWDC 2024 provides insights into using ForEach and other SwiftUI containers to create flexible and composable views.

Here are some key points from the session:

1. Using ForEach for Iteration:

   • You can use ForEach to iterate over a collection of data and generate views for each item. This is useful for creating hierarchical structures like trees.
   • Example: ForEach can be nested within a ViewBuilder to create complex compositions (Demystify SwiftUI containers).

2. Sections and Grouping:

   • SwiftUI's Section view can be used to group items, which is useful for creating sections within your tree structure.
   • Custom containers can be made to support sections by using the ForEach view to iterate over section data (Demystify SwiftUI containers).

3. Custom Containers:

   • You can create custom containers that support flexible composition by using ViewBuilder and other SwiftUI APIs.
   • Example: Refactoring a container to be initialized using a ViewBuilder allows for more flexible content composition (Demystify SwiftUI containers).

For a detailed walkthrough on how to implement these concepts, you can refer to the session "Demystify SwiftUI containers" from WWDC 2024, particularly the chapters on Composition and Sections.
