3,997 Pointsis this the right way to use enums?
I didn't like this video. Why getting into all this trouble to define a function that shouldn't belong there. I mean, a function like colour() that just converts values is clearly a helper function that should be separated from this enum. The Colors enum should have the enumerations of the possible values. Even if this video is just for the sake of letting us know the different possibilities with enum, it ends up being confusing.
So yeah, my question is: is this a "real-life" scenario or use-case of enums, with functions inside them like this?

iOS Development Techdegree Graduate 23,357 PointsHi Vassillis, I don't know if you are doing the techdegree, but inside, there is a project ("Enhancing a Quiz App in iOS"), that you should archive before this video. In the project you have to use many times UIColor, and in this case a function color() like this one, would be very useful.
Anyway, like you said, the video is just for the sake of letting us know the different possibilities with enum.
