NSData is nil

I cannot figure out why my NSData object is nil. Here is code:

    private let apiKey = "f80dccf0d7e91b5d57b748ecbfb5186c"

    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.

        let baseUrl = NSURL(string: "https://api.forecast.io/forecast/\(apiKey)")
        let forecast = NSURL(string: "/42.550949,-83.306352", relativeToURL: baseUrl)
        let forecastData = NSData(contentsOfURL: forecast!, options: nil, error: nil)
