ios - 无法通过 UNUserNotificationCenter 获得重复的每日通知以显示

Question

我的目标是设置一个重复的每日提醒通知。以下代码始终成功显示一次通知，但不会重复，尽管repeat: true在代码中进行了设置。

整个通知代码如下：

    let notificationID = "daily_sleep_alarm"
    let title = "Rest your weary eyes"
    let body = "It's bedtime. The comfort of your blanket beckons you."

    UNUserNotificationCenter.current().removePendingNotificationRequests(withIdentifiers: [notificationID])
    
    let center = UNUserNotificationCenter.current()
    let content = UNMutableNotificationContent()
    content.title = title
    content.body = body
    content.categoryIdentifier = "daily_sleep_alarm"
    content.userInfo = ["customData": "fizzbuzz"]
    content.sound = nil

    var dateComponents = DateComponents()
    dateComponents.hour = hourSelected
    dateComponents.minute = minuteSelected
    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
    let request = UNNotificationRequest(identifier: notificationID, content: content, trigger: trigger)
    center.add(request)

如上所述，此代码一次后无法成功显示通知。我没有其他代码可以清除带有此特定notificationID.

在应用程序启动时，我还会查看可用的待处理通知center.getPendingNotificationRequests，它始终显示为无。

任何关于我需要做什么来正确设置每日重复通知的见解都非常感谢。

我只是每天使用这些简单的代码行

    func setNotifications(with interval: TimeInterval) {
    let content = UNMutableNotificationContent()
    content.title = "Tittle"
    content.subtitle = "Subtle"
    content.body = "Don't forget yourself!"
    content.badge = 1
    
    let trigger = UNTimeIntervalNotificationTrigger(timeInterval: interval,
                                                    repeats: true)
    
    let requestIdentifier = "demoNotification"
    let request = UNNotificationRequest(identifier: requestIdentifier,
                                        content: content, trigger: trigger)
    
    UNUserNotificationCenter.current().add(request,
                                           withCompletionHandler: { (error) in
                                            // Handle error
    })
}
