# pageControllerDidEndLiveTransition(_:)

This message is sent when a transition animation completes.

## Declaration

```swift
@MainActor optional func pageControllerDidEndLiveTransition(_ pageController: NSPageController)
```

## Parameters

- `pageController`: The page controller.

## Discussion

Discussion This message is sent when a transition animation completes either via swipe gesture or one of the page controller’s target-action navigation methods. Your content view is still hidden and you must call the completeTransition() method on pageController when your content is ready to show. If completed successfully, a pageController(_:didTransitionTo:) will already have been sent.
