# view(_:didUpdate:for:)

Tells the delegate that a SpriteKit node’s properties have been updated to match the current state of its corresponding anchor.

```
optional func view(_ view: ARSKView, didUpdate node: SKNode, for anchor: ARAnchor)
```

## Parameters

`view`

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

`node`

The updated SpriteKit node.

`anchor`

The AR anchor corresponding to the node.

## Discussion

Depending on the session configuration, ARKit may automatically update anchors in a session. The view calls this method once for each updated anchor.
