2025 uikit

At WWDC 2025, Apple introduced several updates to UIKit, focusing on a new design system and various architectural improvements. Here are some key highlights:

1. New Design System: UIKit now supports a new material called Liquid Glass, which is translucent and dynamic, enhancing the visual depth and interactivity of apps. This material is integrated into standard components like navigation bars, toolbars, and more. For more details, you can watch the session What’s new in UIKit.

2. Architectural Improvements: UIKit has introduced built-in support for Swift observable objects, allowing for more seamless integration with SwiftUI. This includes automatic observation tracking, which simplifies the process of updating views when data changes. You can learn more about this in the session What’s new in UIKit.

3. Scene Lifecycle: With iOS 26, UIKit apps are required to adopt the UI Scene lifecycle, which enhances app flexibility and portability. This change deprecates many legacy UI application-focused APIs. For more information, refer to the session What’s new in UIKit.

4. Menu Bar on iPadOS: The menu bar from macOS is now available on iPadOS, providing a consistent user experience across devices. This feature supports all menu images, submenus, and more, enhancing the functionality of iPad apps. Details can be found in the session What’s new in UIKit.

5. HDR Color Support: UIKit now includes support for HDR content, allowing apps to provide richer visual experiences. This includes new APIs to manage HDR content effectively. More information is available in the session What’s new in UIKit.

These updates are part of Apple's ongoing efforts to enhance the UIKit framework, making it more powerful and adaptable for developers across all Apple platforms.
