Downloading and parsing json in swift

Question

I'm trying to get the JSON from a website and parse it before putting it inside of an iOS view.

Here's my code;

func startConnection(){
        let urlPath: String = "http://binaenaleyh.net/dusor/"
        var url: NSURL = NSURL(string: urlPath)
        var request: NSURLRequest = NSURLRequest(URL: url)
        var connection: NSURLConnection = NSURLConnection(request: request, delegate: self, startImmediately: false)
        connection.start()
    }

    func connection(connection: NSURLConnection!, didReceiveData data: NSData!){
        self.data.appendData(data)
    }

    func buttonAction(sender: UIButton!){
        startConnection()
    }

    func connectionDidFinishLoading(connection: NSURLConnection!) {
        var err: NSError
        // throwing an error on the line below (can't figure out where the error message is)
        var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
    }

And this is the link for the JSON;

What am I doing wrong here?

Answer 1

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
    }
