# ARSCNDebugOptions

Options for drawing overlay content to aid debugging of AR tracking in a SceneKit view.

```
typealias ARSCNDebugOptions = SCNDebugOptions
```

## Discussion

To use these debugging overlays, add them to the option set in the view’s <doc://com.apple.documentation/documentation/SceneKit/SCNSceneRenderer/debugOptions> property (inherited from the <doc://com.apple.documentation/documentation/SceneKit/SCNView> class).
