weather app keeps returning nil from weatherData

It keeps returning nil for my weatherData.

    let baseURL = NSURL(string: "https://api.forecast.io/forecast/\(apiKey)/")
    let forecastURL = NSURL(string: "37.8267,-122.423", relativeToURL: baseURL)

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

Jamie,

Are you using your own API Key? Make sure it's not the one from the video.

Yes, I'm using my own api key, but still no luck.

try this instead

let baseURL = NSURL(string: "https://api.forecast.io/forecast/\(apiKey)/")
let forecastURL = NSURL(string: "37.8267,-122.423", relativeToURL: baseURL)
let weatherData = NSData(contentsOfURL: forecastURL!)
println(weatherData)

NSURL now returns an optional and needs to be unwrapped.

Hello,

I have tried this solution but it still returns an error. Has anyone got these lines of code to return anything other than "nil"?
