How to use ne swiftui layout

To use the new SwiftUI layout features, you can refer to several sessions from WWDC 2024 that cover different aspects of SwiftUI and its capabilities:

1. Dynamic Layouts in SwiftUI:

   • In the session Get started with Dynamic Type, it is explained how to achieve dynamic layouts using the dynamicTypeSize environment keypath. You can define a property of type AnyLayout that resolves to different layouts based on the selected text size. For example, using an HStack layout for accessibility sizes and a VStack layout for other text sizes.

2. Building Custom Layouts:

   • The session SwiftUI essentials discusses how to create unique custom experiences using low-level APIs. You can build your own control styles, use canvas for high-performance imperative drawing, create completely custom layouts, and even apply custom Metal shaders directly to SwiftUI views.

3. Using Container Views:

   • The session Migrate your TVML app to SwiftUI provides insights into using container views like LazyVGrid and LazyHGrid to create flexible and dynamic layouts. It also covers how to use the containerRelativeFrame modifier to let SwiftUI determine the frame of items automatically, ensuring they align with safe area insets and provide enough room for additional items.

4. Searchable Content:

   • In the same session, Migrate your TVML app to SwiftUI, it is shown how to make content searchable by adding a state property to the view and using the searchable modifier. This allows you to filter content dynamically based on user input.

5. HealthKit and VisionOS:

   • The session Get started with HealthKit in visionOS demonstrates how to use SwiftUI to create spatial health experiences. It includes examples of making charts dynamically resizable and using the onGeometryChange API to observe changes in view size.

Relevant Sessions:

1. Get started with Dynamic Type
2. SwiftUI essentials
3. Migrate your TVML app to SwiftUI
4. Get started with HealthKit in visionOS

These sessions provide a comprehensive overview of how to leverage the new SwiftUI layout features to create dynamic, flexible, and responsive user interfaces.
