Access A Value in Wunderground API

Question

I am trying to incorporate Wunderground into my current project. I have looked at several api tutorials, but I can't seem to figure out how to access a certain part of the API. For example, this is sort of what the API looks like:

{
   "response": {
   "version":"0.1",
   "termsofService":"http://www.wunderground.com/weather/api/d/terms.html",
   "features": {
      "history": 1
   }
   }
    ,
"history": {
    "date": {
    "pretty": "August 9, 2015",
    "year": "2015",
    "mon": "08",
    "mday": "09",
    "hour": "12",
    "min": "00",
    "tzname": "America/Los_Angeles"
    },

Let's say I wanted to return only the hour from the API. How would I do that?

A way to parse JSON without frameworks:

typealias JSONdic = [String: AnyObject]

NSURLConnection.sendAsynchronousRequest(NSURLRequest(URL: nsUrl), queue: NSOperationQueue.mainQueue(), completionHandler: { (_, data, _) -> Void in
    if let data = data, json = data as? JSONdic, history = json["history"] as? JSONdic, hour = history["hour"] as? String {
    println(hour)
}
