# UIVideoEditorControllerDelegate

A set of methods that your delegate object must implement to respond to the video editor.

```
@MainActor protocol UIVideoEditorControllerDelegate : NSObjectProtocol
```

## Overview

The methods of this protocol notify your delegate when the system has saved an edited movie or the user has canceled editing to discard any changes. There’s also a method for responding to errors encountered by the video editor.

The delegate methods are responsible for dismissing the video editor when the operation completes. To dismiss the editor, call the [`dismiss(animated:completion:)`](/documentation/UIKit/UIViewController/dismiss(animated:completion:)) method of the parent controller responsible for displaying the video editor. The video editor is described in [`UIVideoEditorController`](/documentation/UIKit/UIVideoEditorController).

## Topics

### Closing the video editor

[`videoEditorController(_:didSaveEditedVideoToPath:)`](/documentation/UIKit/UIVideoEditorControllerDelegate/videoEditorController(_:didSaveEditedVideoToPath:))

Notifies the delegate after the system finishes saving an edited movie.

[`videoEditorControllerDidCancel(_:)`](/documentation/UIKit/UIVideoEditorControllerDelegate/videoEditorControllerDidCancel(_:))

Notifies the delegate when the user cancels a movie editing operation.

### Handling errors

[`videoEditorController(_:didFailWithError:)`](/documentation/UIKit/UIVideoEditorControllerDelegate/videoEditorController(_:didFailWithError:))

Notifies the delegate when the video editor is unable to load or save a movie.
