In the "What's new in UIKit" session at WWDC 2024, several enhancements and new features for UIKit in iOS 18 were introduced. Here are some of the key updates:

  1. Document Launch Experience: There's a redesigned launch experience for document-based apps, allowing for more control over launch views and support for template document creation. This helps in guiding users to create their first document while maintaining a great browsing experience.

  2. Tabs and Sidebar Updates: Major updates have been made to tabs and sidebars, including a new API to better describe app hierarchy to UITabBarController. This allows for immediate reflection of changes made to UITab instances where the tab is displayed.

  3. Fluid Transitions: New support for fluid transitions across the system enhances the user interface experience by maintaining continuity in UI elements during transitions.

  4. SwiftUI and UIKit Interoperability: iOS 18 enhances the interoperability between SwiftUI and UIKit, making it easier to use them interchangeably. This includes using SwiftUI animation types to animate UIKit views and integrating gesture recognizers from UIKit into SwiftUI hierarchies.

  5. UIUpdateLink: A new feature in iOS 18, UIUpdateLink, simplifies the implementation of complex animations requiring periodic UI updates, offering features like automatic view tracking and low latency mode for drawing applications.
