What's new in SwiftUI at WWDC 2025?

At WWDC 2025, several exciting updates were introduced for SwiftUI. Here are some of the key highlights:

1. Performance Improvements: SwiftUI has seen significant performance enhancements, particularly in areas like lists and scrolling. For instance, lists on macOS with over 100,000 items now load six times faster and update up to 16 times faster. Scrolling performance has also been improved across all platforms.

2. New and Enhanced APIs: SwiftUI now includes new web APIs, rich text editing capabilities, and support for 3D charts. The WebKit framework has been integrated with SwiftUI, allowing for embedding web content directly in apps using a new declarative WebView component.

3. Widgets and Live Activities: Widgets have been expanded to Vision OS and CarPlay, with new APIs for relevance on WatchOS and live activities on CarPlay.

4. RealityKit Integration: SwiftUI has improved its integration with RealityKit, making it easier to work with 3D content. RealityKit entities now conform to Observable, and there are new APIs for coordinate conversion and presenting SwiftUI popovers directly from RealityKit entities.

5. Design System Updates: A new design system has been introduced, providing a bright and fluid experience consistent across Apple platforms. This includes updates to navigation containers, tab bars, and toolbar items.

6. Spatial Layouts: SwiftUI now supports creating 3D layouts using familiar 2D layout tools, making it easier to build spatial experiences, especially on VisionOS.
