The path at which to write the file.
pathcontains a tilde (~) character, you must expand it with

By Expanding Tilde In Path
A flag that specifies whether the file should be written atomically.
YES, the dictionary is written to an auxiliary file, and then the auxiliary file is renamed to
NO, the dictionary is written directly to
YESoption guarantees that
path, if it exists at all, won’t be corrupted even if the system should crash during writing.
YES if the file is written successfully, otherwise
This method recursively validates that all the contained objects are property list objects (instances of
NSDictionary) before writing out the file, and returns
NO if all the objects are not property list objects, since the resultant file would not be a valid property list.
If the dictionary’s contents are all property list objects, the file written by this method can be used to initialize a new dictionary with the class method
dictionary or the instance method
