Syntax change. From the beta 2 release notes:
"
The RawRepresentable protocol that enums with raw types implicitly conform to has been redefined to take advantage of failable initializers. The fromRaw(RawValue) static method has been replaced with an initializer init?(rawValue: RawValue), and the toRaw() method has been replaced with a rawValue property. Enums with raw types can now be used like this:
enum Foo: Int { case A = 0, B = 1, C = 2 }
let foo = Foo(rawValue: 2)! // formerly 'Foo.fromRaw(2)!’
println(foo.rawValue) // formerly 'foo.toRaw()'
"
