# ARPlaneAnchor.Classification.Status.undetermined

ARKit has not yet produced a classification for the plane anchor.

```
case undetermined
```

## Discussion

This status occurs when ARKit is still in the process of plane classification. To be notified when ARKit produces a classification, observe the same plane anchor in a later frame (for example, in the [`session(_:didUpdate:)`](/documentation/ARKit/ARSessionDelegate/session(_:didUpdate:)-3qtt8) or [`renderer(_:didUpdate:for:)`](/documentation/ARKit/ARSCNViewDelegate/renderer(_:didUpdate:for:)) delegate method).
