3. Accessibility Improvements

• Built-in Accessibility Labels: Add additional accessibility information without overriding the framework-provided label.
• Conditional Modifier Support: Enhanced support for accessibility actions based on app intent.

4. Xcode Previews

• Dynamic Linking Architecture: Uses the same build artifacts for previews and build/run, avoiding project rebuilds and increasing iteration speed.

6. Interoperability with UIKit and AppKit

• Gesture Recognition: Use any built-in or custom UI gesture recognizer in SwiftUI view hierarchy.

• Custom Containers: New APIs for creating custom containers.
• Mesh Gradients: Beautiful mesh gradients for more visually appealing designs.

8. Window and Text Customizations

• Window Behavior and Styling: New options to customize window behavior and styling in macOS.
• Text Renderer API: Enables advanced visual effects and playful animations.
