Declaring and using a bit field enum in Swift

Question

How should bit fields be declared and used in Swift?

Declaring an enum like this does work, but trying to OR 2 values together fails to compile:

enum         


        

Answer 1

I think maybe some of the answers here are outdated with overcomplicated solutions? This works fine for me..

enum MyEnum: Int  {

    case One = 0
    case Two = 1
    case Three = 2
    case Four = 4
    case Five = 8
    case Six = 16

}

let enumCombined = MyEnum.Five.rawValue | MyEnum.Six.rawValue

if enumCombined & MyEnum.Six.rawValue != 0 {
    println("yay") // prints
}

if enumCombined & MyEnum.Five.rawValue != 0 {
    println("yay again") // prints
}

if enumCombined & MyEnum.Two.rawValue != 0 {
    println("shouldn't print") // doesn't print
}
