# didReceive(_:)

Delivers new metrics reports to the object registered with the metrics manager.

```
optional func didReceive(_ payloads: [MXMetricPayload])
```

## Parameters

`payloads`

An array of new metrics reports.

## Discussion

The system calls this method at most once per day. It’s safe to process the payload on a separate thread.

> Note:
> MetricKit delivers daily metric reports from iOS 13 or later, and macOS 26 or later.
