swiftui의 새로운 기능 알려줘

SwiftUI has introduced several new features and improvements at WWDC 2024. Here are some of the highlights:

1. Graphics Capabilities: SwiftUI now allows you to mix colors beautifully with a new mix modifier on color. This feature enhances the visual appeal of your apps by blending colors seamlessly.

2. Custom Shader Feature: The ability to precompile shaders before their first use has been added, which helps avoid frame drops caused by lazy shader compilation.

3. Scroll View Enhancements: There are new APIs for fine-grained control over scroll views. You can now react to changes in content, offsets, and content size with the onScrollGeometryChange feature. This allows for more dynamic and responsive UI elements, such as auto-playing videos when they come into view.

4. Accessibility Improvements: SwiftUI has improved its accessibility features, including the ability to add additional accessibility information to controls without overriding the framework-provided labels.

5. Xcode Previews: A new dynamic linking architecture in Xcode previews allows for faster iteration by switching between preview and build without needing to rebuild the project. The previewable macro also simplifies setting up previews by eliminating boilerplate code.

6. Text and Selection Management: SwiftUI now offers programmatic access to text selection within text editing controls, making it easier to manage and interact with text content.

7. Interoperability: SwiftUI has improved interoperability with UIKit and AppKit, allowing for better integration and use of animations and gesture recognizers across different UI frameworks.
