# didCloseWindow(_:)

Called by the app when a window is closed to fire appropriate events with only this extension.

## Declaration

```swift
func didCloseWindow(_ closedWindow: any WKWebExtensionWindow)
```

## Parameters

- `closedWindow`: The window that was closed.

## Discussion

Discussion This method informs only the specific extension of the closure of a window. If the intention is to inform all loaded extensions consistently, you should use the respective method on the extension controller instead.
