What's New in ScrollView

SwiftUI Enhancements

In the session What’s new in SwiftUI, several new features and improvements for ScrollView were introduced:

  1. Programmatic Control: You now have more programmatic control over your scroll views, including more scroll positions to programmatically scroll to, such as the top edge.
  2. Scroll Positions: There are additional scroll positions available, allowing for more precise control.
  3. Content Alignment: You can control content alignment more effectively.
  4. Bouncing Control: You can turn off bouncing along a given axis.
  5. Stopping Scrolling: Programmatically stop scrolling when needed.
  6. Visibility Detection: Detect when a view's visibility changes due to scrolling, enabling experiences like auto-playing videos when they come into view.
  7. Scroll Geometry Change: The onScrollGeometryChange modifier allows you to react to changes in content offsets, content size, and more.

TVOS Enhancements

In the session Migrate your TVML app to SwiftUI, new ScrollView modifiers specific to tvOS 18 were highlighted:

  1. On Scroll Visibility Change: This modifier can be used to change the state when a header section scrolls off-screen.
  2. Scroll Target Behavior: Set the scroll target behavior to be view-aligned to make transitions more definite.

Custom Visual Effects

In the session Create custom visual effects with SwiftUI, custom scroll effects were demonstrated:

  1. Scroll Transition Modifier: This modifier can be used to create unique scroll effects, such as changing the x-offset of an image to create a parallax effect.
  2. Custom Scroll Experiences: The scrollTransition modifier allows for manipulating content in various ways, such as rotating or offsetting elements based on their scroll position.
