To me Angle is a unit with two common representations: radians and degrees.
It's not an enum because it doesn't have two values, it has one value that
you can view in two ways.
Therefore I would make an Angle struct, something like:
//: Angle struct instead of angle enum
import Foundation

Is there a way to restrict the associated values of an enum? For example,
suppose I have this type:
enum Angle {
case radians(Double)
case degrees(Double)
}
I want to ensure that the radians values is always in [0, 2π) and the
degrees values is always in [0, 360). Ideally I would like to
