In the session What’s new in SwiftUI, several enhancements to ScrollView were introduced:
- Programmatic Control: You now have more programmatic control over your scroll views, including the ability to scroll to more positions like the top edge.
- Scroll Positions: There are additional scroll positions you can programmatically scroll to.
- Scroll Behavior Customization: You can turn off bouncing along a given axis, programmatically stop scrolling, and control content alignment.
- On Scroll Geometry Change: A new
onScrollGeometryChangemodifier lets you react to changes in content offsets, content size, and more. - On Scroll Visibility Change: You can detect when a view's visibility changes due to scrolling, allowing for experiences centered around content moving on or off screen.
Additionally, in the session Migrate your TVML app to SwiftUI, new view modifiers specific to ScrollView in tvOS 18 were discussed, such as the onScrollVisibilityChange modifier to handle visibility changes of views when they scroll off screen.
For more advanced customizations, the session Create custom visual effects with SwiftUI demonstrated how to use the scrollTransition modifier to create unique scroll effects, such as rotating and offsetting elements to create a circular carousel or parallax effect.
These enhancements provide developers with more tools to create rich and interactive scrolling experiences in their SwiftUI applications.
