Instance Method


Creates a directory with given attributes at the specified path.


func createDirectory(atPath path: String, withIntermediateDirectories createIntermediates: Bool, attributes: [FileAttributeKey : Any]? = nil) throws



A path string identifying the directory to create. You may specify a full path or a path that is relative to the current working directory. This parameter must not be nil.


If true, this method creates any nonexistent parent directories as part of creating the directory in path. If false, this method fails if any of the intermediate parent directories does not exist. This method also fails if any of the intermediate path elements corresponds to a file and not a directory.


The file attributes for the new directory and any newly created intermediate directories. You can set the owner and group numbers, file permissions, and modification date. If you specify nil for this parameter or omit a particular value, one or more default values are used as described in the discussion. For a list of keys you can include in this dictionary, see Supporting Types. Some of the keys, such as hfsCreatorCode and hfsTypeCode, do not apply to directories.

Return Value

true if the directory was created, true if createIntermediates is set and the directory already exists, or false if an error occurred.


If you specify nil for the attributes parameter, this method uses a default set of values for the owner, group, and permissions of any newly created directories in the path. Similarly, if you omit a specific attribute, the default value is used. The default values for newly created directories are as follows:

  • Permissions are set according to the umask of the current process. For more information, see umask.

  • The owner ID is set to the effective user ID of the process.

  • The group ID is set to that of the parent directory.
