What is the latest update about swiftui

The latest updates about SwiftUI, as presented at WWDC 2024, include several exciting enhancements and new features:

Graphics Capabilities: SwiftUI now allows for more advanced graphics, including a new mix modifier on colors to blend them beautifully. Custom shaders can be precompiled to avoid frame drops caused by lazy shader compilation.
Scroll View Enhancements: There are new APIs for fine-grained control over scroll views, including reacting to changes in content offsets and sizes, and detecting when a view's visibility changes due to scrolling.
Swift 6 Language Mode: SwiftUI has improved its APIs to make it easier to adopt the new Swift 6 language mode, which includes compile-time data race safety. Views in SwiftUI are now implicitly isolated to the main actor by default.
Interoperability Improvements: Significant improvements have been made to the integration of gestures and animations between SwiftUI and UIKit. You can now use any built-in or custom UI gesture recognizer in your SwiftUI view hierarchy, and SwiftUI animations can be used to animate UIKit views.
Customizations and Previews: Xcode Previews now have a dynamic linking architecture for smoother workflows, and SwiftUI has gained new customization options for app appearance, including custom hover effects and window behavior styling.
