A directory to contain temporary files that the export process generates.
Declaration
var directoryForTemporaryFiles: URL? { get set }Discussion
In some configurations, such as performing multipass encoding, an asset writer may need to write temporary files. Use this property value to set the file-system location where it writes temporary files. The system deletes all temporary files after it finishes writing successfully, fails, or you cancel the writing session.
You can set this value after writing starts.
