# HangTimeMetric

A metric that measures app hang time.

## Declaration

```swift
struct HangTimeMetric
```

## Discussion

Discussion This metric corresponds to the MetricResult.hangTime(_:) case. It appears in both intervalEntries and stateEntries when state reporting is enabled. Hang durations that exceed 9 seconds of wall clock time are reported in the histogram’s final bucket. This type replaces the histogrammedApplicationHangTime property of MXAppResponsivenessMetric.
