# CMStepCounter

The number of steps the user has taken with the device.

## Declaration

```swift

```

## Overview

Overview Step information is gathered on devices with the appropriate built-in hardware and stored so that you can run queries to determine the user’s recent physical activity. You use this class to gather both current step data and any historical data.
