Discussion

Use this method to receive the results of a Live Photo capture. When the photo output calls this method, the movie component of the Live Photo has been written to the location specified by the outputFileURL parameter and the Live Photo is ready for consumption. (To receive the still image component of the Live Photo, implement the photoOutput(_:didFinishProcessingPhoto:previewPhoto:resolvedSettings:bracketSettings:error:) method.)

You don’t need to implement this method if you’re not requesting Live Photo capture.

The photo output calls this method only once for each Live Photo capture.
