In the "What's new in SwiftUI" session at WWDC 2024, several enhancements to UIScrollView were introduced. These include:

  1. Fine-Grained Control: New APIs provide more control over scroll views, allowing for deeper integration with the state of a scroll view. This includes reacting to changes in content offsets, content size, and more.

  2. Visibility Detection: You can now detect when a view's visibility changes due to scrolling, enabling experiences centered around content moving on or off-screen, such as auto-playing videos.

  3. Programmatic Control: There are more scroll positions to programmatically scroll to, like the top edge. Additional options include turning off bouncing along a given axis, programmatically stopping scrolling, and controlling content alignment.

For more details, you can refer to the What's new in SwiftUI session at the timestamp 16:18.
