At WWDC 2024, several new features and improvements were introduced for SwiftUI. Here are some of the highlights:
-
Graphics Capabilities: SwiftUI now allows for more advanced graphics, including a new mix modifier for colors that lets you blend colors together. Custom shaders can now be precompiled to avoid frame drops.
-
Scroll View Enhancements: There are new APIs for scroll views, allowing for more control over scroll positions and the ability to detect when a view's visibility changes due to scrolling. This can be used to create experiences like auto-playing videos when they come into view.
-
Text Management: SwiftUI now offers programmatic access to text selection within text editing controls, allowing for features like showing suggested rhymes for selected words.
-
Swift 6 Language Mode: The new Swift 6 language mode introduces compile-time data race safety. SwiftUI has improved its APIs to make it easier to adopt this new language mode.
-
Interoperability: There are significant improvements in the integration of gestures and animations between SwiftUI and UIKit/AppKit, enhancing interoperability.
-
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.
For more detailed information, you can watch the session What’s new in SwiftUI which covers these updates extensively.
