Hi everyone,

Im having some trouble viewing the parse data on my table view. Nothing shows up after I run my code.

class ViewController: UITableViewController {
    var petitions = [Petition]()

    override func viewDidLoad() {
        super.viewDidLoad()

//        let urlString = "https://api.whitehouse.gov/v1/petitions.json?limit=100"
        let urlString = "https://www.hackingwithswift.com/samples/petitions-1.json"

        if let url = URL(string: urlString) {
            if let data = try? Data(contentsOf: url){
                // we're ok to parse
                parse(json: data)
            }
        }
    }

    func parse(json: Data) {
        let decoder = JSONDecoder()

        if let jsonPetitions = try? decoder.decode(Petitions.self, from: json) {
            petitions = jsonPetitions.results
            tableView.reloadData()
        }
    }

    override func numberOfSections(in tableView: UITableView) -> Int {
        return petitions.count
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
        let petition = petitions[indexPath.row]
        cell.textLabel?.text = petition.title
        cell.detailTextLabel?.text = petition.body

        return cell
    }

}

SOLVED: I had numberOfSections instead of numberOfRowsInSection

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return petitions.count
    }

The exact same thing happened to me and I was about to quit and just blame it on a newer version of XCode lol. Thanks!
