# LowLevelDeviceResource

Encapsulates a GPU device resource created by the application. On visionOS, resources must be allocated in shared memory that can be used by the renderer process. Once a device resource is in use by the renderer, changing its contents is unsafe and undefined.

## Declaration

```swift
class LowLevelDeviceResource
```
