Eu estava pesquisando como excluir uma linha de uma exibição de tabela cujos dados estão no Core Data. Não consigo encontrar nada online que possa me ajudar com meu código. Sou realmente novo com o Core Data, então não entendo muito disso.

desde já, obrigado

Este é o meu código

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    guard let appDelegate = UIApplication.shared.delegate as? AppDelegate else { return}

    let managedContext = appDelegate.persistentContainer.viewContext

    let fetchRequest = NSFetchRequest<NSManagedObject>(entityName: "OfficialPT")
    fetchRequest.sortDescriptors = [NSSortDescriptor(key:"createdAt",ascending:false)]


    do {
        AirForceDatabase = try managedContext.fetch(fetchRequest)
    } catch let error as NSError {
        print("Could not fetch. \(error), \(error.userInfo)")
    }
}

func SideMenus ()
{
    if revealViewController() != nil {
        MenuButton.target = revealViewController()
        MenuButton.action = #selector(SWRevealViewController.revealToggle(_:))
        revealViewController().rearViewRevealWidth = 275
        revealViewController().rightViewRevealWidth = 160

        // profileButton.target = revealViewController()
        // profileButton.action = #selector(SWRevealViewController.rightRevealToggle(_:))

        view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())


    }
}

}

extensão HistoryPTViewController: UITableViewDataSource {

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


func tableView(_ tableView: UITableView,
               cellForRowAt indexPath: IndexPath) -> UITableViewCell {




    if let cell = tableView.dequeueReusableCell(withIdentifier: "Cell",for: indexPath) as? HistoryPTTableViewCell {


    let person = AirForceDatabase[indexPath.row]

       cell.OfficialAbsLbl!.text = person.value(forKeyPath: "officialAbs")! as? String
        cell.OfficialPushLbl!.text = person.value(forKeyPath: "officialPush")! as? String

        officialTotalScore = doubleScore
        //officialTotalScore = Double(score)

        print("Score \(officialTotalScore)")

    }
    var createdat :String!

    CompostiveLbl.text = "Composite Score:\n\(officialTotalScore)%"
    createdat = person.value(forKeyPath: "createdAt")! as? String
    print(createdat + "CREATED")
    if officialTotalScore >= 90 {
        print("Excellent")

        officialFinalScoreLbl.text = "Fitness Level:\n Excellent"
    }else if officialTotalScore >= 75 && officialTotalScore <= 89.9 {
