In the context of SwiftUI and ScrollView, several enhancements and features were discussed during the WWDC sessions:
-
ScrollView Modifiers in tvOS 18: New view modifiers specific to ScrollView were introduced, allowing for more control over the appearance and behavior of scrollable content. For example, the
onScrollVisibilityChangemodifier can be used to change the state of a view when it scrolls off-screen, which can be useful for dynamically updating the UI based on scroll position. This was discussed in the session Migrate your TVML app to SwiftUI. -
Custom Scroll Effects: SwiftUI's
scrollTransitionmodifier allows for creating custom scroll effects, such as rotating and offsetting elements based on their position in the scroll view. This can be used to create unique visual experiences, like a circular carousel effect. This was covered in the session Create custom visual effects with SwiftUI. -
Programmatic Control and Enhancements: SwiftUI now offers more programmatic control over scroll views, including the ability to detect when a view's visibility changes due to scrolling. This can be used to create experiences centered around content moving on or off-screen, such as auto-playing videos. Additionally, there are new APIs for fine-grained control over scroll views, such as controlling content alignment and scroll positions. These enhancements were highlighted in the session What’s new in SwiftUI.
These sessions provide a comprehensive overview of the new capabilities and enhancements for ScrollView in SwiftUI, allowing developers to create more dynamic and visually appealing applications.
