как сделать карточки с авто высотой в коллекции

To create cards with automatic height in a SwiftUI collection, you can utilize SwiftUI's flexible layout system. The session "Demystify SwiftUI containers" from WWDC 2024 provides insights into creating custom views and containers that can adapt to different content sizes.

In this session, they discuss using SwiftUI's ForEach and other container views to manage collections of data. You can create a custom card view that adjusts its size based on its content by leveraging SwiftUI's layout system. Here's a basic approach:

1. Use a VStack or HStack: Depending on your layout, use a VStack or HStack to stack your card elements vertically or horizontally.

2. Flexible Layouts: Use SwiftUI's flexible layout modifiers like frame with minHeight or maxHeight to allow the card to adjust its height based on its content.

3. Dynamic Content: Ensure that the content within the card (like text or images) is set to adjust its size dynamically. For example, use Text with .lineLimit(nil) to allow text to wrap and expand the card's height.

4. Custom Containers: If you need more control, consider creating a custom container that uses SwiftUI's GeometryReader to dynamically adjust the size of its child views.

For more detailed guidance, you can refer to the Demystify SwiftUI containers session, particularly the "Composition" chapter, which starts at 03:17. This section discusses how to compose different kinds of content together, which is essential for creating flexible and adaptive UI components like cards with automatic height.
