Creates a request for modifying the specified collection list.
Declaration

- collectionList:
The collection list to be modified.
Return Value
A collection list change request.
Discussion
After you create a change request within a photo library change block, propose changes to the collection’s title or list of child collections with the properties and instance methods of the change request. After Photos runs your change block, the collection list reflects your changes. For details on change blocks, see PHPhotoLibrary.
Use this method when modifying a collection list’s metadata or when adding or removing child collections without regard to their arrangement. To work with indexes in the list of child collections, use the init(for:childCollections:) method instead.
