Доброго дня! Не могу понять, почему мне не приходят локальные уведомления? Один пользователь stackoverflow помог мне собрать этот код, что бы разные локальные уведомления приходили с задержкой. Что в нем не так, и что нужно доделать? Не могли бы Вы помочь исправить это. Я новичок. Код из ViewController и AppDelegate прилагаю.
