Type Method


Removes all versions of a file, except the current one, from the version store.


class func removeOtherVersionsOfItem(at url: URL) throws



The file whose older versions you want to delete. If the file at this URL does not exist, a new file is created at the location.


On input, a pointer to an error object. If an error occurs, this pointer is set to an NSError object with information about the error.

Return Value

true if the older file versions were removed successfully or false if an error occurred.


This method removes all versions except the current one from the version store, freeing up the associated storage space.

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 reflect that only the current version is available. You can use this method to free up disk space by removing versions that are no longer needed.
