JSON dictionary returns nil of 'posts' key

Question

I am trying to use the JSON framework from the stormy project to fetch data from my schools blog. Every time I build and run the app I get the readout "JSON dictionary returns nil of 'posts' key."

The blog URL I am using is http://www.chsd117.org/index.php/app/state-of-lakes

DataService.swift

struct DataService {

func getForecast(completion: (BlogPosts? -> Void)) {
    if let blogURL = NSURL(string: "http://www.chsd117.org/index.php/app/state-of-lakes") {

        let networkOperation = NetworkOperation(url:blogURL)

        networkOperation.downloadJSONFromURL {
            (let JSONDictionary) in
            let blogPosts = self.blogPostsFromJSON(JSONDictionary)
            completion(blogPosts)
        }

    }else{
        println("Could not contruct a valid URL")
    }
}




func blogPostsFromJSON(jsonDictionary: [String: AnyObject]?) -> BlogPosts? {
    if let currentPostDictionary = jsonDictionary?["posts"] as? [String: AnyObject] {
        return BlogPosts(postDictionary: currentPostDictionary)
    } else {
        println("JSON dictonary returned nil of 'posts' key")
        return nil
    }
}

}

NetworkOperation.swift

class NetworkOperation {

lazy var config: NSURLSessionConfiguration = NSURLSessionConfiguration.defaultSessionConfiguration()
lazy var session: NSURLSession = NSURLSession(configuration: self.config)
let queryURL: NSURL

typealias JSONDictionaryCompletion = ([String: AnyObject]?) -> Void

init(url: NSURL) {
    self.queryURL = url
}



func downloadJSONFromURL(completion: JSONDictionaryCompletion) {

    let request: NSURLRequest = NSURLRequest(URL: queryURL)
    let dataTask = session.dataTaskWithRequest(request) {
        (let data, let response, let error) in

        // 1. Check HTTP response for successful GET request


        if let httpResponse = response as? NSHTTPURLResponse {
            switch(httpResponse.statusCode) {
            case 200:
                // 2. Create JSON object with data
                let jsonDictionary =
                NSJSONSerialization.JSONObjectWithData(data, options: nil,
                    error: nil) as? [String: AnyObject]
                completion(jsonDictionary)
            default:
                println("GET request not successful. HTTP status code: \(httpResponse.statusCode)")
            }
        } else {
            println("Error: Not a valid HTTP response")
        }

    }

    dataTask.resume()
}

}

BlogPost.swift

struct BlogPosts {

var title: String?
var author: String?
var thumbnail: String?
var date: String?
var url: NSURL = NSURL()

init(postDictionary: [String: AnyObject]) {
title = postDictionary["title"] as? String
//author = postDictionary["author"] as? String
thumbnail = postDictionary["blog_photo"] as? String
date = postDictionary["entry_date"] as? String
}



func thumbnailURL() -> NSURL {
    return NSURL(string:thumbnail!)!
}

func formattedDate() -> String {
    let dateFormatter = NSDateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
    let tempDate = dateFormatter.dateFromString(date!)
    dateFormatter.dateFormat = "EE MMM, dd"
    return dateFormatter.stringFromDate(tempDate!)
    }

}
