Declaration
func set(_ value: Any?, forKey defaultName: String)Parameters

- defaultName:
The key that contains the setting’s name.
Discussion
Use this method to write property list object types to the defaults store. To store types that aren’t property list objects, archive them to a Data object and use this method to save that data object to the defaults store.
After you call this method, the system generates a didChangeNotification for registered observers.
