To create a new collection view layout in SwiftUI, you can utilize the flexibility of SwiftUI's container views and composition techniques. Here are some steps and concepts from the WWDC sessions that can guide you:
-
Use of LazyVGrid: In the session "Migrate your TVML app to SwiftUI," a
LazyVGridis used to create a grid layout. You can define the number of columns and spacing, and let SwiftUI handle the layout sizing. This is a good starting point for creating a collection view layout. -
Dynamic Layouts: The session "Get started with Dynamic Type" discusses using dynamic layouts that adapt to different text sizes. You can use environment keys like
dynamicTypeSizeto adjust your layout based on accessibility settings, which can be particularly useful for creating responsive collection views. -
View Composition: The session "Demystify SwiftUI containers" highlights the importance of view composition. You can use
ForEachto iterate over your data and create views dynamically. This allows you to build complex layouts by composing smaller views together. -
Custom Containers: If you need more control, you can create custom container views. The session "Demystify SwiftUI containers" explains how to build custom containers using view builders, which can support advanced features like sections and custom modifiers.
For a practical example, you might start by defining a LazyVGrid with a specified number of columns and use a ForEach loop to populate it with your data. You can then apply view modifiers to customize the appearance and behavior of your collection view.
For more detailed guidance, you can refer to the session Demystify SwiftUI containers (03:07) which provides insights into building custom container views in SwiftUI.
Demystify SwiftUI containers
Learn about the capabilities of SwiftUI container views and build a mental model for how subviews are managed by their containers. Leverage new APIs to build your own custom containers, create modifiers to customize container content, and give your containers that extra polish that helps your apps stand out.
Get started with Dynamic Type
Dynamic Type lets people choose their preferred text size across the system and all of their apps. To help you get started supporting Dynamic Type, we’ll cover the fundamentals: How it works, how to find issues with scaling text in your app, and how to take practical steps using SwiftUI and UIKit to create a great Dynamic Type experience. We’ll also show how you can best use the Large Content Viewer to make navigation controls accessible to everyone.
What’s new in UIKit
Explore everything new in UIKit, including tab and document launch experiences, transitions, and text and input changes. We’ll also discuss better-than-ever interoperability between UIKit and SwiftUI animations and gestures, as well as general improvements throughout UIKit.
