Add field to listing in Swift

Question

I am dealing with enumeration and subclass in Swift. Each child brings their new properties that need to be stored in Enum. This listing is declared with some values ​​in the mother class. I would like to add value to this listing. I can’t figure out how to do this, I tried this to no avail:

extension MotherClass { enum Enumeration { case NewProperty } } 

Answer 1

The only way to add elements to enum is to add them directly to its declaration. You cannot add more elements to enum through inheritance or any other extension mechanism: enum must be fully defined at the point of declaration.
