I'm getting a nil value for my url when I try to put in different coordinates.

Question

I'm modifying a weather app I built along side a course here to accept my coordinates. It uses the forecast api for weather data. Here is my url code:

    private let apiKey = "92a0b81218fc51a38a717d1aed2b4a22"

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        refreshActivityIndicator.hidden = true
        getCurrentWeatherData()
    }

    func getCurrentWeatherData() -> Void {
        let baseURL = NSURL(string: "https://api.forecast.io/forecast/\(apiKey)/")
        let forecastURL = NSURL(string: "36.494081, -80.603625", relativeToURL: baseURL)


        let sharedSession = NSURLSession.sharedSession()
        let downloadTask: NSURLSessionDownloadTask = sharedSession.downloadTaskWithURL(forecastURL!, completionHandler: {
            (location: NSURL!, response: NSURLResponse!, error: NSError!) -> Void in...

So the problem is in this line here: let forecastURL = NSURL(string: "36.494081, -80.603625", relativeToURL: baseURL)

The strings of numbers are my coordinates. Theoretically this should work. The coordinates for Alcatraz Island, CA and (test case) Antartica were accepted fine and displayed weather data. Is there a reason my coordinates won't work?

Is this an issue with my code or with the API?

Thanks.

Hi Jonathan,

The issue is the space after the comma in your coordinates, NSURL objects won't accept spaces unless they're URL encoded so once you remove it your code should start working normally again.
