Or, in python:

import json, requests

data = json.loads(requests.get('https://devimages.apple.com.edgekey.net/wwdc-services/ftzj8e4h/6rsxhod7fvdtnjnmgsun/videos.json').content)

for s in data['sessions']:
    if s['year'] == 2015:
        print s['id'], '-', s['title'], '\n', s['download_hd'], '\n'

Or some sloppy Swift 2.0:

import Foundation

let req = NSURLRequest(URL: NSURL(string:"https://devimages.apple.com.edgekey.net/wwdc-services/ftzj8e4h/6rsxhod7fvdtnjnmgsun/videos.json")!)

let data = try NSURLConnection.sendSynchronousRequest(req, returningResponse: nil)

let wwdc = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments)

var sessions = wwdc.valueForKeyPath("sessions") as! NSArray

for session in sessions.sortedArrayUsingDescriptors([NSSortDescriptor(key: "id", ascending: true)])
{
    if session["year"] as! Int == 2015
    {
        let id = session["id"] as! Int
        let title = session["title"] as! String
        let download = session["download_hd"] as! String

        print("\(id) - \(title)\n\(download)\n")
    }
}

…and a gross mini version

import Foundation

let data = NSData(contentsOfURL: NSURL(string:"https://devimages.apple.com.edgekey.net/wwdc-services/ftzj8e4h/6rsxhod7fvdtnjnmgsun/videos.json")!)!
let wwdc = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments)

print(wwdc.valueForKeyPath("sessions.@unionOfObjects.download_hd"))

Gross mini version in Swift 1.2

import Foundation

let data = NSData(contentsOfURL: NSURL(string:"https://devimages.apple.com.edgekey.net/wwdc-services/ftzj8e4h/6rsxhod7fvdtnjnmgsun/videos.json")!)!
let wwdc: AnyObject? = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments, error: nil)

print(wwdc!.valueForKeyPath("sessions.@unionOfObjects.download_hd"))

I made a pyramidal swift version, but github didn't seem to like the abundance of emojis 😦
