# deviceMotion

The latest sample of device-motion data.

## Declaration

```swift
var deviceMotion: CMDeviceMotion? { get }
```

## Mentioned in

Getting processed device-motion data

## Discussion

Discussion If no device-motion data is available, the value of this property is nil. An app that is receiving device-motion data after calling startDeviceMotionUpdates() periodically checks the value of this property and processes the device-motion data.
