Collect and analyze on-device performance metrics and crash diagnostics using MetricKit. Use when setting up MXMetricManager, handling MXMetricPayload or MXDiagnosticPayload, processing crash/hang/disk-write diagnostics via MXCallStackTree, adding custom signpost metrics, or uploading telemetry to an analytics backend.

Collect aggregated performance metrics and crash diagnostics from production devices using MetricKit. The framework delivers daily metric payloads (CPU, memory, launch time, hang rate, animation hitches, network usage) and immediate diagnostic payloads (crashes, hangs, disk-write exceptions) with full call-stack trees for triage.
Register a subscriber as early as possible — ideally in application(:didFinishLaunchingWithOptions:) or App.init. MetricKit starts accumulating reports after the first access to MXMetricManager.shared.
MXMetricPayload arrives approximately once per 24 hours containing aggregated metrics. The array may contain multiple payloads if prior deliveries were missed.
