# ARPlaneAnchor.Classification.none(_:)

No classification is available for the plane anchor.

## Declaration

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

## Discussion

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 value for the reason a plane anchor reports no classification.
