Issues with currentWeatherFromJSON - Stormy App

I just watched the forecastService video and have typed in everything exactly as Pasan has type it, but I am receiving an error in xCode. The error is saying: Cannot invoke 'currentWeatherFromJSON' with an argument list of type '(([String: AnyObject?]))

Can someone please help?

Thanks in advance!

import Foundation

struct ForecastService {

    let forecastAPIKey: String

    let forecastBaseURL: NSURL?

    init(APIKey: String){
    self.forecastAPIKey = APIKey
        forecastBaseURL = NSURL(string: "https://api.forecast.io/forecast/\(forecastAPIKey)/")
    }




    func getForecast(lat: Double, long: Double, completion: (CurrentWeather? -> Void)) {
     if let forecastURL = NSURL(string: "\(lat),\(long)", relativeToURL: forecastBaseURL){

        let networkOperation = NetworkOperation(url: forecastURL)

        networkOperation.downloadJSONFromURL {
            (let JSONDictionary) in
            let currentWeather = self.currentWeatherFromJSON(JSONDictionary)
            completion(currentWeather)

        }

     } else {
        println("Could not construct a valid URL")

        }

    }

    func currentWeatherFromJSON(jsonDictionary: [String: AnyObject]?) -> CurrentWeather? {
        if let currentWeatherDictionary = jsonDictionary?["currently"] as? [String: AnyObject] {
            return CurrentWeather(weatherDictionary: currentWeatherDictionary)

        } else {

            println("JSON dictionary returned nil for 'currently' key")
            return nil
        }
    }

I think that your code is good. I copy pasted it into my 'Stormy' project, and it compiled fine.

Have you tried cleaning your project? goto Build > Clean and then run.
