# ARGeoTrackingStatus.StateReason.worldTrackingUnstable

The position or motion of the device makes geotracking unstable.

## Declaration

```swift
case worldTrackingUnstable
```

## Discussion

Discussion This reason indicates that ARKit’s local-space tracking is functioning at a limited capacity. To retrieve more information about the cause, an app needs to refer to the camera’s trackingState. For the possible causes of this state, see ARTrackingState and ARTrackingStateReason.
