It seems like your question "How now brown cow" doesn't directly relate to the content presented by Apple at WWDC. However, I can provide some information about the latest updates and features discussed at WWDC, particularly focusing on SwiftUI and other related sessions.

Relevant Sessions from WWDC

  1. What’s new in SwiftUI

    • Framework Foundations: SwiftUI has added new APIs that make working with the framework easier, including custom container views and improved interoperability with UIKit and AppKit.
    • Custom Containers: You can now create custom container views with capabilities similar to built-in containers like List and Picker.
    • Ease of Use Enhancements: New APIs for iterating over subviews and sections, and improved support for animations and gestures.

  2. Demystify SwiftUI containers

    • Sections and Customization: Learn how to use new initializers on ForEach and Group to iterate over and transform subviews and sections of a view. Custom containers can support sections and use container values for customization.

  3. Enhance your UI animations and transitions

    • New Transitions: Introduction of new high-level transitions for navigation and presentations, including a new zoom transition in iOS 18.
    • SwiftUI and UIKit Integration: Improved integration between SwiftUI animations and UIKit/AppKit, allowing for seamless animations across framework boundaries.

  4. What’s new in SF Symbols 6

    • Animation Presets: New animation presets like the "breathe" preset for visual feedback in UI elements.
    • SF Symbols App: Updates to the SF Symbols app, including new presets and the animation inspector.

  5. Compose interactive 3D content in Reality Composer Pro

    • Blend Shapes Animation: Use blend shape animations to create lifelike movements by smoothly transitioning between different poses.

  6. SwiftUI essentials

    • Declarative Syntax: SwiftUI's declarative syntax allows you to describe what you want in your UI, and SwiftUI produces the result.
    • Fundamentals of Views: Views are the basic building blocks in SwiftUI, and they are declarative, compositional, and state-driven.

Example of a Specific Feature

For example, if you are interested in the new zoom transition in SwiftUI, you can find more details in the session "Enhance your UI animations and transitions" at the timestamp Zoom transitions in SwiftUI (00:02:07).

If you have any specific questions about these sessions or features, feel free to ask!
