# unsupportedConfiguration

An error that indicates the device lacks support for the session’s configuration.

```
static var unsupportedConfiguration: ARError.Code { get }
```

## Discussion

Call [`isSupported`](/documentation/ARKit/ARConfiguration/isSupported) on an [`ARConfiguration`](/documentation/ARKit/ARConfiguration) to ensure it’s supported before attempting to create and run it on the session with [`runWithConfiguration:`](/documentation/ARKit/ARSession/runWithConfiguration:).
