I'm a new Swift programmer. I'm building my first app with TableViewController + NavigationController.

In my app, I can see this:

If I click on Plus button I can see this View:

Then I compile all field and then I click on OK button. But I have this error:

After click OK this is the code that I try to execute:

@IBAction func tornaAllaLista(_ segue: UIStoryboardSegue){
        do {
            var vistaDettaglio: AggiungiLuceViewController = segue.source as! AggiungiLuceViewController
            if(vistaDettaglio.nuovaLuce != nil && vistaDettaglio.nuovaLuce?.id == 0){
                self.listaLuci.append(vistaDettaglio.nuovaLuce!)
                self.tabella.reloadData()
            }else{

            }
        } catch let errore {
            print("[CDC] problema tornaAllaLista")
            print("  Stampo l'errore: \n \(errore) \n")
        }
    }

EDIT This is the code that I execute when I click on OK button:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        //se il pulsante cliccato è diverso da OK torno indietro
        if sender as? NSObject != self.buttonOK{
            return
        }

        let nomeLuce = self.textNomeLuce.text!
        let pinArduino = Int16(self.textPinArduino.text!)
        let tipoLuce = self.textTipoLuce.text!

        if(nomeLuce.characters.count>0){
            //ho inserito almeno un carattere
            LuciKitCoreDataController.shared.addLuce(descrizione: nomeLuce, pin_arduino: Int(pinArduino!))
            self.nuovaLuce = LuciKit()
            self.nuovaLuce?.descrizione = nomeLuce
            self.nuovaLuce?.pin_arduino = pinArduino!
            self.nuovaLuce?.id = 3
        }else{
            let alert = UIAlertController(title:"Attenzione", message: "Inserire un nome per la Luce", preferredStyle: UIAlertControllerStyle.alert)
            alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))
            self.present(alert, animated:true, completion: nil)
        }

    }

If I try to execute this line code:

self.nuovaLuce?.descrizione = nomeLuce

I have an error
