Subclass with iboutlet tableview Swift

I have a view controller in storyboard with tableview like this:

enter image description here

It's class is this (I linked the iboutlet tableview called 'tabella'):

class RisultatiRicerca: UIViewController , UITableViewDataSource , UITableViewDelegate{

    var codeSearch = 0

    @IBOutlet public var tabella : UITableView!


    override func viewDidLoad() {

        super.viewDidLoad()
        self.tabella.estimatedRowHeight = 50
        self.tabella.rowHeight = UITableViewAutomaticDimension
        self.tabella.delegate = self
        self.tabella.dataSource = self
        self.tabella.reloadData()

    }

    @available(iOS 2.0, *)
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cella = tableView.dequeueReusableCell(withIdentifier: "risu") as! CellaRisultato

        return cella

    }

    @available(iOS 2.0, *)
    public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int{

        return 10
    }

}

My problem is this:

I have to create a subclass of this above, for example this:

class TuttiRicerca: RisultatiRicerca {

    override func viewDidLoad() {

        super.viewDidLoad()
        self.codeSearch = 1
    }
}

but when I present the TuttiRicerca I get this error ('tabella' is nil):

enter image description here

It's like subclass doesnt link the tableview in the storyboard. Can you help me?

If you want IBOutlet references, you cannot just reference TuttiRicera(). How does it know which scene in your storyboard you're trying to use (even if you only have one)?

You need to give the storyboard scene a "storyboard id" and then instantiate it via the storyboard (e.g. storyboard.instantiateViewController(withIdentifier: "..."), not TuttiRicera(). See instantiateViewController(withIdentifier:).
