import XCPlayground
XCPlaygroundPage.currentPage.needsIndefiniteExecution = true

import Foundation

let url = NSURL(string: "https://webapi.tab.com.au/v1/tab-info-service/racing/dates/2015-12-28/meetings?jurisdiction=NSW")!
let task = NSURLSession.sharedSession().dataTaskWithURL(url) { (data, response, error) -> Void in
    if let urlContent = data {
        do {
            let jsonResult = try NSJSONSerialization.JSONObjectWithData(urlContent, options: NSJSONReadingOptions.MutableContainers)

            if let meetings = jsonResult["meetings"] as? NSArray {
                if let dateStr = meetings[0]["meetingDate"] as? String {
                    print(dateStr)
                }
            }

        } catch {
            print("Error")
        }
    }
}
task.resume()

// prints
//
// 2015-12-28
