I am currently learning local notification, but i have a few problems in my test project.


import UIKit
    import UserNotifications

    import SwiftyJSON
    @UIApplicationMain
    class AppDelegate: UIResponder, UIApplicationDelegate {
        var window: UIWindow?

        func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
            // Override point for customization after application launch.

            let navController = window!.rootViewController as! UINavigationController
            let itemsController = navController.topViewController as! ListPlayersVC


            let center = UNUserNotificationCenter.current()

            center.requestAuthorization(options: [.alert, .sound]) {(accepted, error) in
                if !accepted {

                }
            }



            let category = UNNotificationCategory(identifier: "myCategory", actions: [], intentIdentifiers: [], options: [])
           center.setNotificationCategories([category])

            return true

        }


        func scheduleNotification() {

            let content = UNMutableNotificationContent()

                        let todoEndpoint: String = "url1"

извините за плохое редактирование/объяснение..

Я надеюсь, ты поймешь меня сейчас

так что это мой исходный код

что я хочу сделать с локальным уведомлением:

связаться с сервером (по тесту установлено 60 секунд) (работает)

если есть обновление, показать уведомление (работает)

сохранить новое значение в фоновом режиме (self.savechanges()) (не работает), поэтому новое уведомление не будет генерироваться, если для повтора установлено значение true (не работает)

я протестировал свое приложение с повторением триггера false, но мое приложение будет отображать только одно уведомление и игнорировать любые будущие изменения, кроме того, оно игнорирует все элементы в моем плеере, поэтому будет опубликовано только одно уведомление

Надеюсь, вы понимаете, чего я пытаюсь добиться

большое спасибо!
