# renderer(_:didAdd:for:)

Tells the delegate that a SceneKit node corresponding to a new AR anchor has been added to the scene.

```
optional func renderer(_ renderer: any SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor)
```

## Parameters

`renderer`

The [`ARSCNView`](/documentation/ARKit/ARSCNView) object rendering the scene.

`node`

The newly added SceneKit node.

`anchor`

The AR anchor corresponding to the node.

## Discussion

Depending on the session configuration, ARKit may automatically add anchors to a session. The view calls this method once for each new anchor. ARKit also calls this method to provide visual content for any [`ARAnchor`](/documentation/ARKit/ARAnchor) objects you manually add using the session’s [`add(anchor:)`](/documentation/ARKit/ARSession/add(anchor:)) method.

You can provide visual content for the anchor by attaching geometry (or other SceneKit features) to this node or by adding child nodes.

Alternatively, you can implement the [`renderer(_:nodeFor:)`](/documentation/ARKit/ARSCNViewDelegate/renderer(_:nodeFor:)) method to create your own node (or instance of an <doc://com.apple.documentation/documentation/SceneKit/SCNNode> subclass) for an anchor.
