Parsing error-NS serialisation _NS cocoa error

Hi All,

I am facing error while trying to parse json from a URL.

Following is the code:

override func viewDidLoad() {
      super.viewDidLoad()
        print("hello")
        let url=NSURL(string:"http://jsonReports/sample_testkrtk252.json")
        print("hello2")
     
        if let allContactsData=NSData(contentsOfURL:url!)
     
        {
            print(allContactsData)
        do{
       let allContacts: AnyObject! = try NSJSONSerialization.JSONObjectWithData(allContactsData, options: NSJSONReadingOptions.MutableContainers)
            print(allContacts)
            if let json = allContacts as? Array<AnyObject> {
             
                print(json)
                for index in 0...json.count-1 {
                 
                    let data12 : AnyObject? = json[index]
                    print(data12)
                 
                    let collection = data12! as! Dictionary<String, AnyObject>
                    print(collection)
                 
                    print(collection["data11"])
                 
                    let data11 : AnyObject? = collection["data11"]
                    let cont : AnyObject? = collection["cont"]
                 
                    data1.append(data11 as! String)
                    data2.append(cont as! String)
                 
                    print(data1)
                    print(data2)
                }
            }
        }
        catch
        {
            print("error")
        }
        }

And after the successful run i gives the following output:

hello

hello2

error

(lldb)

ALso, it gives the error:

error
NSError Domain: "NSCocoaErrorDomain" - code: 3840  0x00007f8b62c9ef50
_userInfo
__NSDictionaryI * 1 key/value pair 0x00007f8b62dcb3c0

It will be great if someone can look into this. also, is there any better way to parse json in swift.

Thanks,
