In the WWDC 2024 session titled "What’s new in SwiftUI," several new features and improvements were introduced for SwiftUI starting with iOS 18. Here are some of the highlights:

  1. Graphics Capabilities: SwiftUI now includes a new mix modifier on colors, allowing you to blend colors beautifully. Custom shaders can be precompiled to avoid frame drops caused by lazy shader compilation.

  2. Scroll View Enhancements: There are new APIs for fine-grained control over scroll views. You can react to changes in content offsets and sizes, detect view visibility changes due to scrolling, and programmatically control scroll positions and content alignment.

  3. Swift 6 Language Mode: This new mode enables compile-time data race safety. SwiftUI has improved its APIs to make it easier to adopt this new language mode.

  4. Interoperability Improvements: Gesture recognition has been improved, allowing you to use any built-in or custom UI gesture recognizer in your SwiftUI view hierarchy. Animations have also been enhanced, enabling you to set up animations on UIKit or AppKit views and drive them with SwiftUI.

  5. Custom Containers and Mesh Gradients: New features like custom containers and mesh gradients have been introduced, along with scrolling customizations.

For more detailed information, you can refer to the session What’s new in SwiftUI (00:00:07).
