I have this enum in Swift SDK, and need to print the description as a debug message.

@objc public enum ResultCode : UInt16 {
    case noError = 0x0000

    @objc public func description() -> String {
        switch self {
        case .noError:
            return "No Error"
        }
    }
}

The description can not be called in Objc like this:

[taskManager.sendRequest requestWithCompletion:^(ResultCode resultCode) {
    NSString *resultCodeDescription = [resultCode description];//Bad receiver type 'ResultCode' (aka 'enum ResultCode')
    NSLog(@"Result code description: %@", resultCodeDescription);
}];

I know that adding a ResultCode extension in Swift file and a @objc function is a solution, but I prefer to solve this in objc file, how can I approach this?
