How to get status code from NSURLSessionDataTask?

Question

In AFNetworking 3.0 some things was changed. Basicaly, there is no more operations, instead session data tasks. How can I get status code from NSURLSessionDataTask?

This is my block:

    GET("users/check_email", parameters: parameters, progress: nil, success: { sessionDataTask, response in

        // here I need status code of response

        }) { sessionDataTask, error in

            completionBlock(nil, NSError(sessionDataTask: sessionDataTask))
    }

The NSURLSessionDataTask has a response property that can be cast to a NSHTTPURLResponse to get the status code:

Swift Example:

if let urlResponse = sessionDataTask.response as? NSHTTPURLResponse {
    let status = urlResponse.statusCode
}

Objective-C Example:

NSInteger statusCode = 0;

if ([sessionDataTask.response isKindOfClass:[NSHTTPURLResponse class]]) {
    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)sessionDataTask.response;
    statusCode = httpResponse.statusCode;
}
