ios - How to pass swift enum with @objc tag

I need to define a protocol which can be called in a class that use some Objective-c type

But doing that doesn't work:

enum NewsCellActionType: Int {
    case Vote = 0
    case Comments
    case Time
}

@objc protocol NewsCellDelegate {
    func newsCellDidSelectButton(cell: NewsCell, actionType: NewsCellActionType)
}

You get he error

Swift enums cannot be represented in Objective-C

If I don't put the @objc tag on my protocol it'll crash the app as soon as it's called in a class which adopt the protocol AND inherit from an Objective-C type class (like a UIViewController).

So my question is, how should I declare and pass my enum with the @objc tag?

Apple just announced today that Swift 1.2 (included with xcode 6.3) will support exposing enums to objective-c
