What new with SwiftUI

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

1. Graphics and Visual Enhancements: SwiftUI now includes new graphics capabilities, such as the ability to mix colors with a new mix modifier on color. This allows for more dynamic and visually appealing designs.

2. Scroll View Enhancements: There are new APIs for scroll views, providing fine-grained control over scroll positions and the ability to detect changes in view visibility due to scrolling. This enables the creation of experiences centered around content moving on or off-screen, like auto-playing videos.

3. Web Content Integration: SwiftUI now supports embedding web content directly in your app with a full set of WebKit APIs, including a new WebView component. This allows for rich interaction with web content within SwiftUI apps.

4. Performance Improvements: There are significant performance improvements, especially for lists and scrolling. For example, lists on macOS with over 100,000 items now load six times faster.

5. 3D Charts and Rich Text Editing: SwiftUI now supports 3D charts and has enhanced rich text editing capabilities, allowing for more complex and interactive data visualizations and text interactions.

6. Interoperability and Concurrency: SwiftUI has improved interoperability with UIKit and AppKit, making it easier to integrate SwiftUI into existing apps. Additionally, SwiftUI leverages Swift concurrency for better performance and responsiveness.

7. Widgets and Controls: Widgets have been expanded to Vision OS and CarPlay, and there are new APIs for customizing widget appearances and interactions.
