Enum multiple cases with the same value in Swift

Question

In C you could make your enums have this:

typedef enum _Bar {     A = 0,     B = 0,     C = 1 } Bar; 

In Swift I want to make the equivalent. However, the compiler complains that it isn't unique. How do I tell it that I want two cases to have the same value?

enum Bar : Int {     case A = 0     case B = 0 // Does not work     case C = 1 } 

I've tried

case A | B = 0 

and

case A, B = 0 

But it doesn't seem to work as I want it to.

Swift doesn't support duplicated values (or "aliases" semantically). If you don't mind, you can mimic it by using something like this:

enum Foo: Int {     case Bar = 0      static var Baz:Foo {         get {             return    Bar         }     }     static var Jar:Foo {         get {             return    Foo(rawValue: 0)!         }     } } 

With recent version of Swift, this can be shortened like this:

enum Foo: Int {     case bar = 0      static var baz:Foo { .bar }     static var jar:Foo { Foo(rawValue: 0)! } } 

Note that Swift has changed their naming convention of enum variants from PascalCase to camelCase.
