How to compare value of the same Enumeration? (== comparison does not work!)

Question

Looks like Enumerations in Swift cannot be compared for equality. Here is the code I would expect to work:

let areEqual = MyEnum.SomeEnumValue == MyEnum.SomeEnumValue

However, this does not compile and throws error: Cannot invoke '==' with an argument list of type '(MyEnum, MyEnum)'.

Is it possible to compare 2 Enumeration values using == operator or do I really write switch-case for that?

EDIT

Here is self containing example. Just past it to playground and you should see the compilation error.

import UIKit

enum MyEnum {
    case SomeValue(Int)
    case OtherValue(Double)
    case ThirdValue
}

let areEqual = MyEnum.ThirdValue == MyEnum.ThirdValue

Looks a bit like Swift bug because it lets you compare Enumerations that has no associated values without complains. So I hope this is not expected behaviour (allowing to compare some Enumerations but not others).

Answer 1

This works for me:

enum CompassPoint {
    case North
    case South
    case East
    case West
}

let isEqual = CompassPoint.North ==  CompassPoint.South
//false

another example:

enum CompassPoint: Int {
    case North = 1, South, East, West
}

let isEqual = CompassPoint.North ==  CompassPoint.South
//false

this will work also:

enum MyEnum {
    case SomeValue
    case OtherValue
    case ThirdValue
}


let areEqual = MyEnum.ThirdValue == MyEnum.ThirdValue

but your example the enum has different types. You will only be able o compare various assigned to them.
