Cast from 'NSData?' to unrelated type 'NSDictionary' always fails - yellow error

I get that error with this code:

                    if (error == nil) {
                    let dataObject = NSData(contentsOfURL: location)

                    let weatherDictionary: NSDictionary = NSJSONSerialization.dataWithJSONObject(dataObject!, options: nil, error: nil) as! NSDictionary
                    }

Get the data and then turn it into a dictionary using NSKeyedUnarchiver

let weatherData = NSJSONSerialization.dataWithJSONObject(dataObject!, options: nil, error: nil)

let weatherDictionary: NSDictionary = NSKeyedUnarchiver.unarchiveObjectWithData(weatherData!) as! NSDictionary
