# MetricResult

An enumeration that represents a single metric value from a metric report entry.

## Declaration

```swift
enum MetricResult
```

## Mentioned in

Analyzing app performance with MetricKit

## Discussion

Discussion MetricResult unifies all metric types into a single enum. You receive MetricResult values by iterating the values array on a MetricReport.IntervalEntry, or the values array on a MetricReport.StateEntry. for result in entry.values {     switch result {     case .cpuTime(let metric):         process(metric)     case .peakMemory(let metric):         process(metric)     case .hangTime(let metric):         process(metric)     @unknown default:         break     } } Use the metricGroup property to filter or categorize results without exhaustive switching when you only need a subset of metric types. This type replaces the typed metric properties of MXMetricPayload, such as cpuMetrics, memoryMetrics, and networkTransferMetrics.
