# existingPlane

A point on a real-world plane (already detected with the [`planeDetection`](/documentation/ARKit/ARWorldTrackingConfiguration/planeDetection-swift.property) option), without considering the plane’s size.

```
static var existingPlane: ARHitTestResult.ResultType { get }
```

## Discussion

When searching for this result type, ARKit can return any point coplanar with an already detected plane, regardless of whether that plane’s already detected [`extent`](/documentation/ARKit/ARPlaneAnchor/extent) or [`geometry`](/documentation/ARKit/ARPlaneAnchor/geometry) includes that point. (That is, this result type searches the infinite extensions of detected planes.)

An existing plane search can return any number of results, depending on how many already-detected planes the hit test ray intersects (if any).
