Swift: Weather App - Making a Network Call not connecting to API to return data

I have followed step by step as the instructor has in the whether app.

http://teamtreehouse.com/library/build-a-weather-app-with-swift/pulling-data-from-the-web/making-a-network-call

I receive no error and the app runs. However, the console returns nil. The first time I ran the app it returned the data from the API and Forecast was updated and showed I made a call. I have not been able to make a call again. Here is my code.

import UIKit

class ViewController: UIViewController {

    private let apiKey = "6638a13657b81ecbe08a47749ecfa9b7"

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

        let baseURL = NSURL(string: "https://api.forecast.io/forecast/\(apiKey)")
        let forecastURL = NSURL(string: "32.302452,-80.975017", 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.
    }
}

Try changing the URL from

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

to

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