# ARPlaneAnchor.Classification.Status.notAvailable

ARKit cannot currently provide plane classification information.

```
case notAvailable
```

## Discussion

Plane classification is available only on iPhone XS and iPhone XS Max devices. On other devices, all plane anchors always indicate a classification status of [`ARPlaneAnchor.Classification.Status.notAvailable`](/documentation/ARKit/ARPlaneAnchor/Classification-swift.enum/Status/notAvailable).

A classification status of [`ARPlaneAnchor.Classification.Status.notAvailable`](/documentation/ARKit/ARPlaneAnchor/Classification-swift.enum/Status/notAvailable) can also occur if the plane classification process is temporarily unavilable.
