I am new to iOS development. I am trying to load a JSON, here's my function:
func loadmyJSON (urlPath: String) { let url: NSURL = NSURL(string: urlPath)! let session = NSURLSession.sharedSession() let task = session.dataTaskWithURL(url, completionHandler: {data, response, error -> Void in println("Task completed") if(error != nil) { // If there is an error in the web request, print it to the console println("error not nil::::::") println(error.localizedDescription) } var err: NSError? var jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: &err) as NSDictionary if(err != nil) { // If there is an error parsing JSON, print it to the console println("JSON Error \(err!.localizedDescription)") } let results: NSArray = jsonResult["variants"] as NSArray dispatch_async(dispatch_get_main_queue(), { self.jsonTable = results self.productView!.reloadData() }) }) But I am getting this error:
error not nil::::::
The operation couldn’t be completed. (NSURLErrorDomain error -1002.)
I am able to get the JSON in the browser through the same URL. I have tried reading this Apple Doc, but I can't get the description.
What does this error code mean?

NSURLErrorDomain error -1002 means NSURLErrorUnsupportedURL or kCFURLErrorUnsupportedURL. It indicates that a bad URL was provided, in most cases, missing http:// from the URL prefix.
The list of all NSURLErrorDomain codes can be found here:
In addition to the above answer, one of the reasons why this could happen is,
You might have set the Allow Arbitrary Loads to false in your Info.plist and the URL you are trying to load is not on a secured server.
The solution to this is either set it to true, or move to a secure connection i.e https://.
Hope it helps someone. All the best.
I encounter the same issue and found that key parameter was missing from URL. You need to set Google map key value for key parameter in URL you are using to make request. This can be occur if you are missing other keys.
