what new swiftui | Ask WWDC

At WWDC 2024, Apple introduced several new features and improvements in SwiftUI. Here are some of the highlights:

Graphics Capabilities: SwiftUI now allows for more advanced graphics, including a new mix modifier on colors to blend them together. Custom shaders can be precompiled to avoid frame drops.
Scroll View Enhancements: There are new APIs for more granular control over scroll views, including reacting to changes in content and offsets, and detecting when a view's visibility changes due to scrolling.
Text Management: SwiftUI now offers programmatic access to text selection within text editing controls, allowing for features like suggested rhymes or text completions.
Swift 6 Language Mode: The new Swift 6 language mode introduces compile-time data race safety, and SwiftUI has improved its APIs to support this.
Interoperability: Significant improvements have been made to the integration of gestures and animations, allowing for better interoperability between SwiftUI and UIKit/AppKit.
Accessibility: New accessibility features include conditional modifier support and app intent-based accessibility actions.
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.
