Controls whether the device-movement display is shown.

```
var showsDeviceMovementDisplay: Bool { get set }
```

## Discussion

When a device requires movement (for example, to calibrate the compass), the value of this property indicates if the system’s device-movement display should be shown. When a device requires movement, the block handler of type [`CMDeviceMotionHandler`](/documentation/CoreMotion/CMDeviceMotionHandler) reports the [`CMErrorDeviceRequiresMovement`](/documentation/CoreMotion/CMErrorDeviceRequiresMovement) error once. By default, this property is <doc://com.apple.documentation/documentation/Swift/false>.
