# HasAnchoring

An interface that enables anchoring of virtual content to a real-world
object in an AR scene.

```

## Topics

### Getting the component

[`anchoring`](/documentation/RealityKit/HasAnchoring/anchoring)

The component that describes how the virtual content is anchored to the
real world.

### Identifying the AR anchor

[`anchorIdentifier`](/documentation/RealityKit/HasAnchoring/anchorIdentifier)

The identifier of the AR anchor with which the anchor entity is
associated, or `nil` if it isn’t currently anchored.

### Moving the anchor

[`reanchor(_:preservingWorldTransform:)`](/documentation/RealityKit/HasAnchoring/reanchor(_:preservingWorldTransform:))

Changes the entity’s anchoring, preserving either the world transform or
the local transform.
