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.
