# device

The Metal device this renderer uses for rendering.

## Declaration

```swift
var device: (any MTLDevice)? { get }
```

## Discussion

Discussion Use this property to create or look up other Metal resources that use the same device as your SceneKit renderer. note: This property is valid only for scene renderers whose renderingAPI value is SCNRenderingAPI.metal. You create a SceneKit view that renders using Metal with the preferredRenderingAPI initialization option or in Interface Builder, or an SCNRenderer that uses Metal with the init(device:options:) method. For OpenGL-based scene renderers, this property’s value is always nil.
