我的目标是设置一个将在未来 N 秒内第一次发生的通知，然后每 N 秒重复一次。

}

func startRequest() {
    let content = UNMutableNotificationContent()
    content.body = bodyText
    content.categoryIdentifier = categoryIdentifier
    content.sound = UNNotificationSound.default()

    let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, repeats: true)
    trigger.nextTriggerDate()
    let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)

    let center = UNUserNotificationCenter.current()
    center.add(request)
}

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) …
