App Terminating, need support.

Hey i am having an issue with: 2014-10-09 17:48:35.906 stormY[1879:63421] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[_NSPlaceholderData initWithContentsOfURL:options:error:]: nil URL argument' this is from the LOG.

This is my code

```import UIKit

class ViewController: UIViewController {

private let apiKey = "7b0e6589397f393a900cd6fc4df61906"



override func viewDidLoad() {

    super.viewDidLoad()

    // Do any additional setup after loading the view, typically from a nib.

    //19.429418, -99.205582"

    let baseURL = NSURL(string:"https://api.forecast.io/forecast/\(apiKey)/")

    let forecastURL = NSURL(string:"19.429418, -99.205582", relativeToURL: baseURL)

    let weatherData = NSData.dataWithContentsOfURL(forecastURL, options: nil, error: nil)



    println(weatherData)

}



override func didReceiveMemoryWarning() {

    super.didReceiveMemoryWarning()

    // Dispose of any resources that can be recreated.

Any ideas or suggestions?

try removing the space between your coordinates

let forecastURL = NSURL(string:"19.429418,-99.205582", relativeToURL: baseURL)

this worked for me. It always amazes me how the simplest thing can make the entire program not function.
