Answer 1

You can try this.

let myJSON =  try NSJSONSerialization.JSONObjectWithData(urlData!, options: NSJSONReadingOptions.MutableContainers) as! NSDictionary

            let keys = myJSON.allKeys
            print(keys)

            let values = myJSON.allValues
            print(values)

            let dict = values[2]
            print(dict)

            let dictAssdata = dict["assdata"]
            print(dictAssdata)

Hope it help you.

Your key assdata contains String JSON response so that for getting Dictionary from it you need to convert it to first data.

if let jsonStr = yourResponse["assdata"] as? String {
    if let data = jsonStr.dataUsingEncoding(NSUTF8StringEncoding) {
        do {
             let dic = try NSJSONSerialization.JSONObjectWithData(data, options: []) as? [String:AnyObject]
        } catch let error as NSError {
             print(error)
        }
    }
}
