What is container view controller

A container view controller in the context of SwiftUI is a type of view that can hold and manage other views. SwiftUI provides several built-in container views, such as HStack, VStack, and List, which are used to organize and layout their child views. These container views use a trailing ViewBuilder closure to define their content, allowing for both static and dynamic content composition.

In the session Demystify SwiftUI containers, it is explained that container views can support advanced capabilities like grouping content into sections with configurable headers and footers, and applying container-specific modifiers for customization. The session also introduces new APIs for building custom container views that can support these capabilities, enhancing flexibility and customization options in SwiftUI applications.

For more detailed information, you can refer to the session "Demystify SwiftUI containers" which covers topics such as composition, sections, and customization of container views.
