scroll view | Ask WWDC

Apple's WWDC sessions have introduced several enhancements and features related to scroll views, particularly in SwiftUI and UIKit. Here are some highlights:

SwiftUI Scroll Effects: In the session "Create custom visual effects with SwiftUI," new scroll transition modifiers are discussed. These allow developers to create unique scroll effects, such as changing the rotation and offset of elements based on their position in the scroll view. This can be used to create effects like a circular carousel or parallax scrolling. Create custom visual effects with SwiftUI
Scroll View Modifiers in tvOS 18: The session "Migrate your TVML app to SwiftUI" introduces new view modifiers specific to scroll views in tvOS 18. These modifiers can be used to manage the visibility of background images as content scrolls off-screen. Migrate your TVML app to SwiftUI
Design System and Scroll Edge Effects: In the session "Get to know the new design system," scroll edge effects are discussed. These effects help clarify where UI and content meet, providing a subtle transition that enhances the user experience. Get to know the new design system
UIKit and Scroll Views: The session "Build a UIKit app with the new design" covers how scroll views automatically apply visual treatments to ensure legibility when overlapping with navigation or toolbars. This includes the use of edge effects for custom container views. Build a UIKit app with the new design
Performance Enhancements: The "Platforms State of the Union" session highlights performance improvements in scrolling, such as idle prefetching, which helps reduce the chance of dropping frames during fast scrolling. This is particularly beneficial for lists and tables with large amounts of data.

These sessions provide a comprehensive overview of the new capabilities and improvements in scroll view handling across Apple's platforms.
