Passing JSON data to a label in Swift - json

Question

I'm new to coding and have a (hopefully easy) question.
I am trying to display JSON data as a label using swift. I'm not getting any errors but nothing is showing up using the following code:
let task = NSURLSession.sharedSession().dataTaskWithURL(url) { (data, response, ErrorType) -> Void in
if let urlContent = data {
do {
let jsonResult = try NSJSONSerialization.JSONObjectWithData(urlContent, options: NSJSONReadingOptions.MutableContainers)
print(jsonResult)
let text = jsonResult as? String
self.textLabel.text = text
} catch {
print("JSON serialization failed")
}
}
}
task.resume()
Thanks!

Just update your label into main thread this way:
dispatch_async(dispatch_get_main_queue()) {
self.textLabel.text = text
}
UPDATE:
You can use SwiftyJSON for that.
And below is your working code with that library:
import UIKit
class ViewController: UIViewController {
var dict = NSDictionary()
#IBOutlet weak var authorLbl: UILabel!
#IBOutlet weak var quoteLbl: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
let urlString = "http://api.theysaidso.com/qod.json"
if let url = NSURL(string: urlString) {
if let data = try? NSData(contentsOfURL: url, options: []) {
let json = JSON(data: data)
print(json)
let auther = json["contents"]["quotes"][0]["author"].stringValue
let quote = json["contents"]["quotes"][0]["quote"].stringValue
authorLbl.text = auther
quoteLbl.text = quote
}
}
}
}
