# SignpostRecord

A record of a signpost event associated with a diagnostic report.

## Declaration

```swift
struct SignpostRecord
```

## Mentioned in

Analyzing app performance with MetricKit

## Discussion

Discussion This describes a single signpost event that was active around the time of a diagnostic event. Each record carries a subsystem, category, and name that identify the signpost, along with an interval covering the signpost’s duration. For instantaneous signposts, the start and end of the interval are equal, giving a duration of zero. Access signpost records through signpostData on the diagnostic report’s environment. This type replaces MXSignpostRecord.
