# init(configuration:)

Returns a web extension controller initialized with the specified configuration.

```
init(configuration: WKWebExtensionController.Configuration)
```

## Parameters

`configuration`

The configuration for the new web extension controller.

## Return Value

An initialized web extension controller, or nil if the object could not be initialized.

## Discussion

This is a designated initializer. You can use [`init()`](/documentation/WebKit/WKWebExtensionController/init()) to initialize an instance with the default configuration. The initializer copies the specified configuration, so mutating the configuration after invoking the initializer has no effect on the web extension controller.

[`init()`](/documentation/WebKit/WKWebExtensionController/init())

Returns a web extension controller initialized with the default configuration.
