# StateReportingDomain

A value that identifies a reporting scope for segmenting metric data.

## Declaration

```swift
struct StateReportingDomain
```

## Mentioned in

Monitoring app performance with MetricKit

## Discussion

Discussion StateReportingDomain is RawRepresentable and ExpressibleByStringLiteral, so create values using string literals. Use reverse DNS notation to avoid naming collisions: let manager = MetricManager(     enabledStateReportingDomains: ["com.example.app.session"] ) Pass a set of StateReportingDomain values to init(enabledStateReportingDomains:) to receive metrics segmented by each domain’s recorded states. Use StateReporter.reporter(for:stableMetadata:) from the StateReporting framework to obtain a StateReporter. Call reportTransition(to:stableMetadata:) on it to emit state transitions for MetricKit to aggregate.
