At WWDC 2024, several improvements to scroll views in SwiftUI were introduced. Here are some of the key enhancements:
-
Programmatic Control: You now have more programmatic control over scroll views, including the ability to scroll to specific positions like the top edge. This allows for more precise control over the scrolling experience.
-
Scroll Geometry Changes: The new
onScrollGeometryChangemodifier lets you react to changes in content offsets and sizes, enabling more dynamic and responsive UI designs. -
Visibility Detection: You can detect when a view's visibility changes due to scrolling. This can be used to create experiences centered around content moving on or off the screen, such as auto-playing videos.
-
Scroll Transitions: The
scrollTransitionmodifier allows for custom scroll effects, such as creating a parallax effect or a circular carousel effect by manipulating the rotation and offset of elements based on their scroll position. -
Visual Effects: You can use scroll transitions and visual effect modifiers to create custom scroll view effects, such as adjusting scale, rotation, and color properties based on the position of an element on the screen.
For more detailed information, you can refer to the session What’s new in SwiftUI (16:18) which covers scrolling enhancements. Additionally, the session Create custom visual effects with SwiftUI (01:29) discusses scroll effects in more detail.
