# init(name:id:kind:)

Creates a manufacturer-declared extension feature.

```
init(name: String, id: String?, kind: HMAccessory.ManufacturerFeature.Kind)
```

## Parameters

`name`

The localized display name for the content.

`id`

The content identifier.

`kind`

## Discussion

Don’t call this initializer directly.

Access the instances of this type
in the [`manufacturerFeatures`](/documentation/HomeKit/HMAccessory/manufacturerFeatures) property.
To display a feature,
call [`showManufacturerExtension(for:featureID:)`](/documentation/HomeKit/HMAccessory/showManufacturerExtension(for:featureID:))
with that feature’s identifier and kind.
