swiftui new feature

At WWDC, Apple introduced several new features in SwiftUI. Here are some highlights:

1. Graphics Capabilities: SwiftUI now includes a new mix modifier for 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: There are new APIs for fine-grained control over scroll views, including the ability to react to changes in content and offsets, and detect when a view's visibility changes due to scrolling.

3. Text and Selection: SwiftUI now offers programmatic access to text selection within text editing controls, allowing you to manage text selection and provide text suggestions.

4. Web Content Integration: WebKit now has a full set of SwiftUI APIs, including a new WebView for showing web content in your app, allowing for rich interaction with web pages.

5. 3D Charts: SwiftUI supports 3D charts, enabling you to show plots in three dimensions with new Z-specific modifiers.

6. Improved Interoperability: There are significant improvements in the integration of gestures and animations between SwiftUI and UIKit/AppKit, allowing for better interoperability.

7. 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.
