JSON TableView Swift Error - ios

Question

I'm trying to populate a tableview with this JSON URL. I validated the URL, and it works fine. My code is at fault. I have a 'Repository.swift' file with a class inside. Here's my code: I can't resolve the issue.
var repositories = [Repository]()
override func viewDidLoad() {
super.viewDidLoad()
let reposURL = NSURL(string: "https://www.kimonolabs.com/api/7flcy3qm?apikey=gNq3hB1j0NtBdAvXJLEFx8JaqtDG8y6Y")!
if let JSONData = NSData(contentsOfURL: reposURL) {
if let json = NSJSONSerialization.JSONObjectWithData(JSONData, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary {
if let reposArray = json["items"] as? [NSDictionary] {
for item in reposArray {
repositories.append(Repository(json: item))
}
}
}
}
}
func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return self.repositories.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
cell.textLabel?.text = repositories[indexPath.row].Event
cell.detailTextLabel?.text = repositories[indexPath.row].Hasta
return cell
}

You need to add try catch
I fixed your code
override func viewDidLoad() {
super.viewDidLoad()
let reposURL = NSURL(string: "https://www.kimonolabs.com/api/7flcy3qm?apikey=gNq3hB1j0NtBdAvXJLEFx8JaqtDG8y6Y")!
if let JSONData = NSData(contentsOfURL: reposURL) {
do{
let json = try NSJSONSerialization.JSONObjectWithData(JSONData, options: .MutableContainers)
if let reposArray = json["items"] as? [NSDictionary] {
for item in reposArray {
// repositories.append(Repository(json: item))
}
}
}catch {
//do whatever
}
}
}
Kindly try it.
