Trying to parse a json array with swiftJson

Question

I am downloading a file which does just fine. I am then trying to parse this json to get a value out from it. This is where the error occurs. The file downloads fine I think. Here is what I have so far

 func parseYoutubeVideo(json : String)
{

    if let data = json.dataUsingEncoding(NSUTF8StringEncoding)
    {
        let newJson = JSON(data: data)
        //Get the youtube video from the Json data
        print("Parsing Video")
        self.myVideo = newJson["video"].stringValue
        //load the video
        print("Video parsed: " + self.myVideo)
        self.myYoutubePlayer .loadWithVideoId(myVideo)



    }
}
//Function to log into the server and retrive data
func  downloadVideoUrl(myUrl : String)
{
    print("Downloading video")
    Alamofire.request(.GET, myUrl)
        .authenticate(user: "admin", password: "admin")
        .validate()
        .responseString { response in
            print("Success: \(response.result.isSuccess)")
            print("Response String: \(response.result.value)")

            if(response.result.isSuccess == true)
            {
                self.parseYoutubeVideo(response.result.value!)
                //self.parseYoutubeVideo(self.testConfigJson)

            }else
            {
                //remove player from the view
                 self.myYoutubePlayer.removeFromSuperview()
            }



    }
}

This is what alamofire give me

Success: true
Response String: Optional("[ {\n  \"video\" : \"zKevpV_Qo7A\"\n} ]")

Is there something I am missing on how to do this or am i doing this completely wrong. This is how you parse out a json array right?

Thank you for any help with this

What is your JSON? I could help you if you pasted the JSON response. — Mtoklitz113

This is what it should give me [ { "video": "zKevpV_Qo7A" } ] — MNM

Use this code:

let data = response.result.value!.dataUsingEncoding(NSUTF8StringEncoding)
var json: NSArray?

do {
json = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) as! NSArray
}
catch error as NSError {
print(error)
}
let video = (json[0] as! NSDictionary)["video"] as String
