Meet the Now Playing framework

Find and fix performance problems faster than ever. Join us to explore how MetricKit equips you with vital performance metrics and actionable diagnostics to help you understand exactly where your app has opportunities for improvements. We’ll also cover how to intersect your app’s metrics and diagnostics by app state by using the StateReporting framework, providing you with the full picture to investigate optimizations in your app’s experience.

Discover Music Understanding, a new framework that lets your app analyze audio across six dimensions, on device: key, rhythm, structure, pace, instrument activity, and loudness. And use the Music Understanding Lab sample app to visualize each result.

Learn how to evaluate model-driven experiences using the Evaluations framework. In a probabilistic world, unit tests alone won’t suffice. Discover how to define metrics, automatically grade outputs, and aggregate statistics to ensure your AI-powered features perform reliably across Apple’s platforms.

Discover Core AI, Apple’s new framework for on-device AI model deployment. Tour the ecosystem, from Python libraries for converting, authoring, and optimizing models, to a Swift API for simple plug-and-play inference and advanced use cases with strict latency and memory requirements. Explore the new Core AI models repository with ready-to-run examples for popular architectures. See how deep Xcode integration, including ahead-of-time model compilation, streamlines the workflow so you can deliver smarter, more responsive app experiences.
