# ARPlaneAnchor.Classification.none(_:)

No classification is available for the plane anchor.

```
case none(ARPlaneAnchor.Classification.Status)
```

## Discussion

Plane classification can take longer than plane detection, and ARKit reports classifications only for planes where it has a high confidence in the result. See the associated [`ARPlaneAnchor.Classification.Status`](/documentation/ARKit/ARPlaneAnchor/Classification-swift.enum/Status) value for the reason a plane anchor reports no classification.
