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.

Get a first look at Now Playing — a Swift framework that connects your app’s media playback to system surfaces like the Lock Screen, Control Center, Dynamic Island, and CarPlay. Discover how to publish playback state and respond to commands using its observable API. Explore remote playback sessions, a new capability that lets your app represent media playing on external devices and bring full playback controls to those same system surfaces.
