SwiftUI scroll indicator

In the WWDC 2024 sessions, there are several updates and features related to SwiftUI scroll indicators and scroll views:

1. New Scroll View Modifiers: In the session titled "Migrate your TVML app to SwiftUI," there are new view modifiers specific to scroll views in tvOS 18. These modifiers allow you to remove background images when the header section scrolls off-screen and to change the state based on scroll visibility. This can be seen in the Migrate your TVML app to SwiftUI session.

2. Scroll Geometry and Control: The session "What’s new in SwiftUI" introduces new APIs for scroll views, providing fine-grained control over scroll positions and the ability to react to changes in content offsets and sizes. This includes programmatically stopping scrolling and controlling content alignment. You can learn more about these enhancements in the What’s new in SwiftUI session.

3. Custom Scroll Effects: In the session "Create custom visual effects with SwiftUI," the scroll transition modifier is highlighted. This modifier allows you to create custom scroll effects, such as rotating and offsetting elements based on their position in the scroll view, creating unique visual experiences like a circular carousel effect. This is discussed in the Create custom visual effects with SwiftUI session.

These sessions provide a comprehensive overview of the new capabilities and enhancements for scroll views in SwiftUI, allowing developers to create more dynamic and visually appealing user interfaces.
