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.

Relevant Timestamps:

These sessions provide a comprehensive overview of the new elements and capabilities introduced in SwiftUI for visionOS, enhancing both the visual and interactive aspects of your applications.
