Apple introduced several new UI features and design updates at WWDC, particularly focusing on UIKit and SwiftUI. Here are some highlights:

  1. Liquid Glass Material: A new expressive material called Liquid Glass has been introduced. It is translucent, dynamic, and enhances the visual depth of UI components like navigation bars, toolbars, and sidebars. This material is designed to make apps feel more alive and responsive.

  2. UIKit Enhancements:

    • Fluid Transitions: UIKit now supports more fluid and interruptible slide transitions, allowing users to interact with content without waiting for animations to complete.
    • Background Extension View: This new tool allows content to surface under the sidebar's large glass platter, maintaining visual continuity.
    • UI Update Link: A new feature in iOS 18 that simplifies implementing complex animations requiring periodic UI updates, offering better performance and battery efficiency.
  3. SwiftUI Updates:

    • New Design System: SwiftUI has been updated to support the new design system, providing a consistent experience across Apple platforms. This includes a glassy appearance for sidebars and updated tab bars.
    • Expanded Features: SwiftUI now supports web content and rich text, along with new graphics capabilities like color mixing and precompiled shaders to avoid frame drops.
  4. Design System: The new design system aims to create a universal design language across Apple platforms, focusing on elevating content, consistency, and usability. It introduces rounded forms influenced by the geometry of fingers for more natural touch interactions.
