enums - Swift Enumerations .toRaw and .fromRaw with Xcode 6.1

Question

In Xcode 6.1, the enumerations toRaw and fromRaw functions don't work anymore:

enum TestEnum : String {
    case A = "a"
    case B = "b"
}

if let a = TestEnum.fromRaw("a") {
    prinln(a.toRaw())
}

Errors:

'TestEnum' does not have a member named 'toRaw'
'TestEnum.Type' does not have a member named 'fromRaw'

Answer 1

Create an enum from a raw using the failable initializer with rawValue and get the raw value using the attribute rawValue.

if let a = TestEnum(rawValue: "a") {
     println(a.rawValue)
}
