Instance Method


Determines the type of relationship that exists between a directory and an item.


func getRelationship(_ outRelationship: UnsafeMutablePointer<FileManager.URLRelationship>, ofDirectoryAt directoryURL: URL, toItemAt otherURL: URL) throws



A pointer to a variable in which to put the relationship between directoryURL and otherURL. For a list of possible values, see FileManager.URLRelationship.


The URL of the directory that potentially contains the item in otherURL. The URL in this parameter must specify a directory. This parameter must not be nil.


The URL of the file or directory whose relationship to directoryURL is being tested. This parameter must not be nil.

Return Value

true if the relationship between the items was successfully determined, or false if an error occurred.


Use this method to determine the relationship between an item and a directory whose location you already know. If the relationship between the items is determined successfully, this method sets the value of the outRelationship parameter to an appropriate value. The directory may contain the item, it may be the same as the item, or it may not have a direct relationship to the item.
