Enum within a class as argument

I'm building a class to act as my API helper and I've nested an enum inside my class to show the response state:

class API {
  enum Response {
    case Success, Error, ServerError, ClientError
  }

  func load(handleResponse ((API.Response, JSON?) -> Void)) {
    // Load in data with Alamofire
    // Call handleResponse(.Success, data) at some point
  }
}

To use my API, I am trying to write something like the following:

API.load { (status: API.Response, data: JSON?) in
  ...
}

I'm getting an error as follows with my code above:

Cannot convert value of type '(API.Response, JSON?) -> ()' to expected argument type 'API'

It seems like the '.' in the type is a problem, but I'm not sure how to fix it.

Please try this

class API {
    enum Response {
        case Success, Error, ServerError, ClientError
    }

    class func load(handleResponse: ((API.Response, JSON?) -> ())) {

    }
}


API.load { (response, json) -> () in

}
