Cannot display part of JSON data - ios

Question

I've been trying to display certain JSON data to the storyboard but for some reason have been unable. The part of it that works, is the the var name, which is a string, and it doesn't have to be converted so it just works. The part that I am having an issue with is trying to convert two Int64's to strings, but I have them listed as AnyObjects. It's really confusing me, but here is the issue in code:
The program runs fine, but it doesn't display any information for profileIconId and summonerLevel.
import UIKit
class ViewController: UIViewController, NSURLConnectionDelegate {
lazy var data = NSMutableData()
#IBOutlet weak var searchField: UITextField!
#IBOutlet weak var name: UILabel!
#IBOutlet weak var summonerLevel: UILabel!
#IBOutlet weak var profileIconId: UILabel!
#IBAction func enterButton(sender: AnyObject) {
startConnection()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func startConnection(){
let urlPath: String = "https://na.api.pvp.net/api/lol/na/v1.4/summoner/by-name/soon2challenger?api_key=(removed my private api key for obvious reasons)"
var url: NSURL = NSURL(string: urlPath)!
var request: NSURLRequest = NSURLRequest(URL: url)
var connection: NSURLConnection = NSURLConnection(request: request, delegate: self, startImmediately: false)!
connection.start()
}
func connection(connection: NSURLConnection!, didReceiveData data: NSData!){
self.data.appendData(data)
}
func buttonAction(sender: UIButton!){
startConnection()
}
func connectionDidFinishLoading(connection: NSURLConnection!) {
var err: NSError
// throwing an error on the line below (can't figure out where the error message is)
var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as! NSDictionary
let include: AnyObject = jsonResult.objectForKey(searchField.text)!
var name1: AnyObject = include.objectForKey("name")!
var summLevel: AnyObject = include.objectForKey("summonerLevel")!
var profIconId: AnyObject = include.objectForKey("profileIconId")!
name.text = name1 as? String
profileIconId.text = profIconId as? String
summonerLevel.text = summLevel as? String
println(name1)
println(summLevel)
println(profIconId)
}
}
The code that processes and displays everything is in the connectionDidFinishLoading function at the very bottom of the code.

Here's a refactor of your connectionDidFinishLoading(_:) method that properly unwraps the values using optional bindings.
You might also consider using NSNumberFormatter instead of "\()".
func connectionDidFinishLoading(connection: NSURLConnection) {
var err: NSError?
if let jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: &err) as? NSDictionary,
let include = jsonResult.objectForKey(searchField.text) as? NSDictionary {
if let name1 = include[ "name" ] as? String {
name.text = name1
println(name1)
}
if let summLevel = include[ "summonerLevel" ] as? NSNumber {
summonerLevel.text = "\(summLevel.integerValue)"
println(summLevel)
}
if let profIconId = include[ "profileIconId" ] as? NSNumber {
profileIconId.text = "\(profIconId.integerValue)"
println(profIconId)
}
}
}
