Present list of items in tableview from Realm database

Question

I am successfully downloading and printing data from Realm database. Here is my log:

Item(id: Optional(0), name: Optional("Item (0)"), descr: Optional("Description of item (0)"),
     icon: Optional("http://192.168.1.101:8080/api/items/0/icon.png"),
     url: Optional("http://192.168.1.101:8080/api/items/0")))

Now I have to assign those values on actual list and I am getting a clean sheet tableview. How to do it properly? I am using .xib as tablewViewCell. I am thankful for any tips.

class ItemRealm : Object {
    dynamic var id = 0
    dynamic var name = ""
    dynamic var desc = ""
    dynamic var icon = ""


    override class func primaryKey() -> String? {
        return "id"
    }
}


class ViewController: UIViewController, UITableViewDataSource,    UISearchBarDelegate {

    @IBOutlet weak var searchBar: UISearchBar!
    @IBOutlet weak var tableView: UITableView!


    let realm = try! Realm()
    let results = try! Realm().objects(ItemRealm.self).sorted(byKeyPath: "id")

    let SERVER_URL = "http://192.168.1.101:8080/api/items"

    override func viewDidLoad() {
        super.viewDidLoad()

        Alamofire.request(SERVER_URL).responseJSON { response in
            let items = [Item].from(jsonArray: response.result.value as! [Gloss.JSON])
            print(items?[0] as Any)

            try! self.realm.write {
                for item in items! {
                    let itemRealm = ItemRealm()
                    itemRealm.id = item.id!
                    itemRealm.name = item.name!
                    itemRealm.desc = item.descr!
                    itemRealm.icon = item.icon!
                    self.realm.add(itemRealm)
                }
            }
            _ = self.realm.objects(ItemRealm.self)
           // print(items?[0] as Any)
        }
        // Do any additional setup after loading the view.
        tableView.register(UINib(nibName: "TableViewCell", bundle: nil), forCellReuseIdentifier: "TableViewCell")
    }

    // MARK: - UITableView data source
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return results.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell =  tableView.dequeueReusableCell(withIdentifier: "TableViewCell") as! TableViewCell

        var object: ItemRealm
        object = self.results[indexPath.row] as ItemRealm

        cell.item = object

        return cell
    }

}

I think you are missing self.tableView.reloadData() after getting data from the response. Consider also assigning fetched data to your results variable.
