The URL to which to write the dictionary.
A flag that specifies whether the output should be written atomically.
true, the dictionary is written to an auxiliary location, and then the auxiliary location is renamed to
false, the dictionary is written directly to
trueoption guarantees that
a, if it exists at all, won’t be corrupted even if the system should crash during writing.
flagis ignored if

true if the location is written successfully, otherwise
This method recursively validates that all the contained objects are property list objects (instances of

If the dictionary’s contents are all property list objects, the location written by this method can be used to initialize a new dictionary with the class method
dictionary or the instance method
