Which session explains how to display a 3D model in a swiftui view? I believe it was a model of the Earth

Optimize your 3D assets for spatial computing

Dive into an end-to-end workflow for optimized 3D asset creation. Discover best practices for optimizing meshes, materials, and textures in your digital content creation tool. Learn how to harness shader graph, baking, and material instances to enhance your 3D scene while optimizing performance. Take advantage of native tools to work more effectively with your assets and improve your app’s performance.

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.

Explore object tracking for visionOS

Find out how you can use object tracking to turn real-world objects into virtual anchors in your visionOS app. Learn how you can build spatial experiences with object tracking from start to finish. Find out how to create a reference object using machine learning in Create ML and attach content relative to your target object in Reality Composer Pro, RealityKit or ARKit APIs.

Migrate your TVML app to SwiftUI

SwiftUI helps you build great apps on all Apple platforms and is the preferred toolkit for bringing your content into the living room with tvOS 18. Learn how to use SwiftUI to create familiar layouts and controls from TVMLKit, and get tips and best practices.

Discover RealityKit APIs for iOS, macOS and visionOS

Learn how new cross-platform APIs in RealityKit can help you build immersive apps for iOS, macOS, and visionOS. Check out the new hover effects, lights and shadows, and portal crossing features, and view them in action through real examples.

Break into the RealityKit debugger

Meet the RealityKit debugger and discover how this new tool lets you inspect the entity hierarchy of spatial apps, debug rogue transformations, find missing entities, and detect which parts of your code are causing problems for your systems.

Dive deep into volumes and immersive spaces

Discover powerful new ways to customize volumes and immersive spaces in visionOS. Learn to fine-tune how volumes resize and respond to people moving around them. Make volumes and immersive spaces interact through the power of coordinate conversions. Find out how to make your app react when people adjust immersion with the Digital Crown, and use a surrounding effect to dynamically customize the passthrough tint in your immersive space experience.

Bring your iOS or iPadOS game to visionOS

Discover how to transform your iOS or iPadOS game into a uniquely visionOS experience. Increase the immersion (and fun factor!) with a 3D frame or an immersive background. And invite players further into your world by adding depth to the window with stereoscopy or head tracking.
