tell me about latest swift ui changes

At WWDC 2024, Apple introduced several exciting updates to SwiftUI. Here are some of the key changes:

1. Graphics Capabilities: SwiftUI now includes a new mix modifier on colors, allowing you to blend colors beautifully. Additionally, custom shaders can be precompiled to avoid frame drops caused by lazy shader compilation.

2. Scroll View Enhancements: New APIs provide fine-grained control over scroll views. You can now react to changes in content, offsets, and content size with the onScrollGeometryChange modifier. This includes detecting when a view's visibility changes due to scrolling, enabling experiences like auto-playing videos.

3. Interoperability with UIKit and AppKit: SwiftUI now allows animations to be set up on UIKit or AppKit views and driven by SwiftUI, including fully custom animations. Gesture recognition has been improved, allowing built-in or custom UI gesture recognizers to be used in SwiftUI view hierarchies.

4. Custom Containers and Mesh Gradients: SwiftUI introduces custom containers and mesh gradients, providing more flexibility in UI design.

5. TabView Syntax: A new syntax for TabView in SwiftUI helps catch common errors at build time, ensuring consistency in tab selection types.
