# isProducedByAccessory

A Boolean value that indicates whether the system receives the location from an external accessory.

```
var isProducedByAccessory: Bool { get }
```

## Discussion

Core Location sets [`isProducedByAccessory`](/documentation/CoreLocation/CLLocationSourceInformation/isProducedByAccessory) to `true` if the system retrieved the location from an external accessory attached to the device, such as a Made for iPhone GPS dongle or CarPlay. Otherwise, the default value is `false`.
