setVideoAtPath(_:completionBlock:)

Replaces the video data in receiver with the video at a given URL.

Declaration

func setVideoAtPath(_ videoPathURL: URL!, completionBlock: (@Sendable (URL?, (any Error)?) -> Void)!)

func setVideoAtPath(_ videoPathURL: URL!) async throws -> URL?

Parameters

videoPathURL:
An URL that specifies the location of video data.
completionBlock:
The block invoked after the save operation completes.
If the application is able to edit the asset, the completion block returns the same asset URL as the receiver, because a new asset is not created.
If the application is not able to edit the asset, the completion blocks return a nil asset URL and an ALAssetsLibraryWriteFailedError.

Discussion

important:

You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration:

func setVideoAtPath(_ videoPathURL: URL!) async throws -> URL?

For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.

Before invoking this method, you should check the isEditable property of the asset to determine whether it is possible to replace the video data.
