Spotlight on sessions, Digital Lounges, and labs

Our final day packs in a bunch of great sessions: Discover how you can accelerate machine learning with Metal, bring multiple windows to your SwiftUI app, and learn how to optimize your app or game’s memory and battery consumption.

Accelerate machine learning with Metal

Discover how you can use Metal to accelerate your PyTorch model training on macOS. We'll take you through updates to TensorFlow training support, explore the latest features and operations of MPS Graph, and share best practices to help you achieve great performance for all your machine learning...
