# webView(_:previewingViewControllerForElement:defaultActions:)

Called when the user performs a peek action.

## Declaration

```swift
optional func webView(_ webView: WKWebView, previewingViewControllerForElement elementInfo: WKPreviewElementInfo, defaultActions previewActions: [any WKPreviewActionItem]) -> UIViewController?
```

## Parameters

- `webView`: The web view invoking the delegate method.
- `elementInfo`: The information associated with the element.
- `previewActions`: An array of default actions used by the element.

## Return Value

Return Value Return nil to use Webkit’s default preview behavior. Returning a view controller allows webView(_:commitPreviewingViewController:) to be invoked when the user performs a pop action.

## Discussion

Discussion To use the default actions, your app must return the actions to be run in your view controller’s implementation of previewActionItems.
