VisionOS SwiftUI New Elements

Sessions Mentioned:

1. Get started with HealthKit in visionOS
2. What’s new in SwiftUI
3. SwiftUI essentials

Key Points:

1. Standard System Appearance:

   • SwiftUI components like TabView and sheets automatically adopt the standard system appearance in visionOS.
   • Standard components translate well to visionOS, ensuring a consistent look and feel.

2. Dynamic Resizing:

   • New SwiftUI API: onGeometryChange allows observing changes in view size.
   • This can be used to dynamically resize charts and other elements, enhancing the user experience on the spatial canvas of visionOS.

3. New Graphics Capabilities:

   • SwiftUI introduces a new mix modifier on Color to blend colors.
   • Custom shaders can now be precompiled to avoid frame drops.

4. Scroll View Enhancements:

   • New APIs provide fine-grained control over scroll views.
   • onScrollGeometryChange allows reacting to changes in content offsets and sizes.
   • Visibility detection for views due to scrolling, enabling experiences like auto-playing videos.

5. Volumetric Content:

   • SwiftUI supports adding volumetric content for visionOS, leveraging the spatial canvas to create immersive experiences.

6. Custom Layouts and Controls:

   • SwiftUI provides low-level APIs for creating custom control styles, layouts, and even applying custom Metal shaders directly to views.
