Downloading and parsing json in swift

These two functions worked for me:

    func getJSON(urlToRequest: String) -> NSData{
        return NSData(contentsOfURL: NSURL(string: urlToRequest))
    }

    func parseJSON(inputData: NSData) -> NSDictionary{
        var error: NSError?
        var boardsDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(inputData, options: NSJSONReadingOptions.MutableContainers, error: &error) as NSDictionary

        return boardsDictionary
    }
