Спасибо @Sachin Raut
чал, как удалить строку из табличного представления, данные которого находятся в Базовых данных. Я не могу найти в Интернете ничего, что помогло бы мне с моим кодом. Я действительно новичок в Core Data, поэтому я не очень разбираюсь в этом.
заранее спасибо
Это мой код
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 ()

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())
}
}
