- Design great visionOS apps
Feel free to ask about any specific topics or sessions!

Bring your machine learning and AI models to Apple silicon
Learn how to optimize your machine learning and AI models to leverage the power of Apple silicon. Review model conversion workflows to prepare your models for on-device deployment. Understand model compression techniques that are compatible with Apple silicon, and at what stages in your model deployment workflow you can apply them. We’ll also explore the tradeoffs between storage size, latency, power usage and accuracy.

Deploy machine learning and AI models on-device with Core ML
Learn new ways to optimize speed and memory performance when you convert and run machine learning and AI models through Core ML. We’ll cover new options for model representations, performance insights, execution, and model stitching which can be used together to create compelling and private on-device experiences.

What’s new in USD and MaterialX
Explore updates to Universal Scene Description and MaterialX support on Apple platforms. Discover how these technologies provide a foundation for 3D content creation and delivery, and learn how they can help streamline your workflows for creating great spatial experiences. Learn about USD and MaterialX support in RealityKit and Storm, advancements in our system-provided tooling, and more.
