Getting an error here with the new code: "fatal error: unexpectedly found nil while unwrapping an Optional value"

This is my code that's causing the error:

        let baseURL = NSURL(string: "https://api.forecast.io/forecast/\(apiKey)/")
        // Do any additional setup after loading the view, typically from a nib.

        let forecastURL = NSURL(string: "40.712908, -73.949399", relativeToURL: baseURL)

        let weatherData = NSData(contentsOfURL: forecastURL!, options: nil, error: nil)

Ah, nm, found the error, I had a space between my coordinates when I copied and pasted from Google Maps. Removed the space, and now it works fine.

let forcastURL = NSURL(string: "00.000000, __ -00.000000", relativeToURL: baseURL)

REMOVE SPACE __ and replace to

let forcastURL = NSURL(string: "00.000000,-00.000000", relativeToURL: baseURL)
