To build custom SwiftUI views, you can refer to the session titled "SwiftUI essentials" from WWDC 2024. This session covers the fundamentals of creating custom views in SwiftUI, including how to conform to the View protocol and use the body property to define the view's appearance. It also discusses the use of view modifiers to customize views and the importance of composition in building complex user interfaces.
For more advanced techniques, the session "Demystify SwiftUI containers" provides insights into building custom container views in SwiftUI. This session explains how to use view builders to define content dynamically and how to create flexible containers that support various compositions.
If you're interested in exploring 3D layouts, the session "Meet SwiftUI spatial layout" introduces new tools for building 3D experiences with SwiftUI, which can be useful if you're looking to extend your custom views into 3D space.
Here are the relevant sessions you might want to explore:
- SwiftUI essentials (Fundamentals of views)
- Demystify SwiftUI containers (Composition)
- Meet SwiftUI spatial layout (3D views)
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.
SwiftUI essentials
Join us on a tour of SwiftUI, Apple’s declarative user interface framework. Learn essential concepts for building apps in SwiftUI, like views, state variables, and layout. Discover the breadth of APIs for building fully featured experiences and crafting unique custom components. Whether you’re brand new to SwiftUI or an experienced developer, you’ll learn how to take advantage of what SwiftUI has to offer when building great apps.
Meet SwiftUI spatial layout
Explore new tools for building spatial experiences using SwiftUI. Learn the basics of 3D SwiftUI views on visionOS, customize existing layouts with depth alignments, and use modifiers to rotate and position views in space. Discover how to use spatial containers to align views in the same 3D space, helping you create immersive and engaging apps.
