Return an enum with associated value where AnyObject is expected

Question

I'm trying to use an enum with associated values to capture the result of a flow of Reactive Cocoa 2.5 RACSignal operations. The API specifies that signals contain AnyObject values. I get an error that Cannot convert value of type 'MyEnum' to expected argument type 'AnyObject!'. Is there any simple way to wrap my enum values in a reference so that this will work?

I suppose you have to ask if an enum is really the best option here. But if it is, can you not just create your own wrapper?

enum MyEnum {
    case MyCase(String)
}

class MyEnumWrapper {
    var myEnum: MyEnum

    init(_ myEnum: MyEnum) {
        self.myEnum = myEnum
    }
}

func takeAnyObject(a: AnyObject!) {

    if let myEnumW = a as? MyEnumWrapper {
        print(myEnumW.myEnum)
    }

}

let tmp = MyEnumWrapper(.MyCase("Hello"))
takeAnyObject(tmp)
