New APIs in SwiftUI
SwiftUI has introduced several new APIs and enhancements this year. Here are some of the key updates:
-
Graphics Capabilities:
- Mix Modifier on Color: Allows blending colors together by a given amount.
- Custom Shader Precompilation: Enables precompiling shaders before their first use to avoid frame drops caused by lazy shader compilation.
-
Scroll View Enhancements:
- On Scroll Geometry Change: React to changes in content, offsets, content size, and more.
- Visibility Detection: Detect when a view's visibility changes due to scrolling, useful for creating experiences like auto-playing videos.
- Programmatic Control: More control over scroll positions, turning off bouncing along a given axis, programmatically stopping scrolling, and controlling content alignment.
-
Text and Selection Management:
- Programmatic Text Selection: Access and control text selection within text editing controls.
-
Interoperability:
- UIKit and AppKit Integration: Improved interoperability with UIKit and AppKit, including gesture recognition and animations.
- HostingViewController: Embed SwiftUI views into UIKit or AppKit view hierarchies.
-
Accessibility:
- Conditional Modifier Support: New accessibility features such as conditional modifier support and app intent-based accessibility actions.
-
Xcode Previews:
- Dynamic Linking Architecture: Switch between a preview and build and run without needing to rebuild the project.
- Previewable Macro: Use state directly in previews, eliminating the need for boilerplate code.
-
Custom Containers and Mesh Gradients:
- Custom Containers: New ways to create custom containers.
- Mesh Gradients: Enhanced gradient capabilities for more complex visual effects.
-
Swift 6 Language Mode:
- Compile Time Data Race Safety: New language mode that enables compile-time data race safety.
- Main Actor Annotation: Views in SwiftUI are now marked with the main actor annotation, ensuring they are implicitly isolated to the main actor by default.
