At WWDC 2024, several updates and new features were introduced for SwiftUI. Here are some of the key changes:
-
Graphics Capabilities: SwiftUI now allows for more advanced graphics, including a new mix modifier on colors that lets you blend colors together by a specified amount. Additionally, custom shaders can now be precompiled to avoid frame drops caused by lazy shader compilation.
-
Scroll View Enhancements: There are new APIs for more granular control over scroll views. You can now react to changes in content, offsets, and content size with the
onScrollGeometryChangefeature. This allows for dynamic experiences, such as auto-playing videos when content moves on or off the screen. -
Text Selection and Suggestions: SwiftUI now offers programmatic access to text selection within text editing controls. You can also add text suggestions to any text field, which appear as a dropdown menu.
-
Swift 6 Language Mode: SwiftUI has improved its APIs to support the new Swift 6 language mode, which includes compile-time data race safety. Views in SwiftUI are now marked with the main actor annotation, meaning they are isolated to the main actor by default.
-
Interoperability Improvements: There have been significant improvements in the integration of gestures and animations between SwiftUI and other frameworks like UIKit and AppKit. You can now use any built-in or custom UI gesture recognizer in your SwiftUI view hierarchy.
For more detailed information, you can refer to the session What’s new in SwiftUI (16:18) which covers scrolling enhancements and other updates.
