# deviceMotionUpdateInterval

The interval, in seconds, for providing device-motion updates to the block handler.

```
var deviceMotionUpdateInterval: TimeInterval { get set }
```

## Discussion

The system supplies device-motion updates to the block handler specified in [`startDeviceMotionUpdates(to:withHandler:)`](/documentation/CoreMotion/CMMotionManager/startDeviceMotionUpdates(to:withHandler:)) at regular intervals determined by the value of this property. The interval units are in seconds. The value of this property is capped to minimum and maximum values; the maximum value is determined by the maximum frequency supported by the hardware. If your app is sensitive to the intervals of device-motion data, it should always check the timestamps of the delivered [`CMDeviceMotion`](/documentation/CoreMotion/CMDeviceMotion) instances to determine the true update interval.
