What is the point of having an extension on enum?

Can somebody explain what is the benefit of having an extension on a Story enum in this video? Why don't we just include those properties from extension within an enum? How does this change functionality?

And in general (on other objects) why is better to have an extension rather than including those "extended" features within an object?

I know one way wherer this is useful (when we don't have access to the object (like Apple's objects that we use but cannot observe)) So we can add something on to them but with our objects I just don't see how this is useful. Please help!

I think a lot of people use extensions to organize their code better and for readability purposes. You are correct that it doesn't really change the underlying functionality.

Here's an article that helped me with the topic: https://www.natashatherobot.com/using-swift-extensions/
