remove()
Remove this version object and its associated file from the version store.
Declaration
func remove() throwsDiscussion
This method removes this version object and its file from the version store, freeing up the associated storage space. You must not call this method for the current file version—that is, the version object returned by the currentVersionOfItem(at:) method.
You should always remove file versions as part of a coordinated write operation to a file. In other words, always call this method from a block passed to a file coordinator object to initiate a write operation. Doing so ensures that no other processes are operating on the file while you remove the version information.
If successful, subsequent requests for the versions of the file do not include this version object (or any object with the same information). You can use this method to free up disk space by removing versions that are no longer needed.
