Auto Layout is a key feature in Apple's development ecosystem, particularly within UIKit, which allows developers to create responsive and adaptive user interfaces. At WWDC 2024, several sessions touched on layout-related topics:

  1. What’s new in UIKit: This session introduced automatic trait tracking in iOS 18, which simplifies handling changes in traits like size classes. This feature automatically updates the layout when traits change, improving performance and reducing manual code. You can learn more about this in the Automatic trait tracking section.

  2. Get started with Dynamic Type: This session discussed how to adapt layouts dynamically in response to text size changes, especially for accessibility. It highlighted using UIStackView in UIKit to adjust layouts based on the preferred content size category. More details can be found in the Dynamic layouts section.

  3. Migrate your TVML app to SwiftUI: This session explained how SwiftUI can automatically adjust layouts using modifiers like containerRelativeFrame, which helps in creating adaptive interfaces that respond to different screen sizes and orientations. This is covered in the Shelves section.

These sessions provide insights into how Apple is enhancing layout capabilities across its platforms, making it easier for developers to create flexible and adaptive user interfaces.
