swiftui avoid subviews

In SwiftUI, avoiding subviews is about understanding the distinction between declared and resolved subviews. Declared subviews are the ones you define in your code, while resolved subviews are what actually appear on the screen when the app runs. For example, a ForEach view is a declared subview that generates a collection of resolved subviews. This concept is crucial for optimizing performance and organizing your code effectively.

SwiftUI's declarative system allows you to break up views into multiple components without compromising performance. This is because SwiftUI views are value types defined using structs, which are efficient and allow for flexible composition. You can use container views like HStack, VStack, and Group to manage layout and composition without worrying about performance hits.

For more detailed information, you can refer to the session Demystify SwiftUI containers (07:11) which discusses the concept of declared and resolved subviews in depth.
