Xcode Update: Treehouse Code is broken and does not compile URL to forecast.io

I got the code working in playground with: let absoluteURL = forecastURL?.absoluteURL

But in xcode I get an error when I use it. Any help would be MUCH appreciated.

Here is my code for ForecastService function:

import Foundation

struct ForecastService {

let forecastAPIKey: String
let forecastBaseURL: NSURL?

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

func getForecast(lat: Double, long: Double, completion: (CurrentWeather? -> Void)) {
    if let forecastURL = NSURL(string: "37.8267,-122.423/", relativeToURL: forecastBaseURL)

    {

        let networkOperation = NetworkOperation(url: forecastURL)

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

        }
    }
    else {
        print("Could not construct valid URL.")
    }
}

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


        } else {
            print("JSON Dictionary returned nil for 'currenty' key")
            return nil
        }
}

}
