Repeat local notification every n days

Question

I'm trying to create application that will send local notifications every n days.

I has DailyRepeat structure that contains notification info:

struct DailyRepeat: BaseRepeat {

    var title: String
    var body: String
    var date: Date

    var day: Int

}

And method that schedule notification:

func notifyDaily(at notification: DailyRepeat) {
    let content = generateContent(title: notification.title, body: notification.body)
    let dateComponents = DateComponents(day: notification.day, hour: notification.date.time.hours, minute: notification.date.time.minutes)
    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
    let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)

    notificationCenter.add(request)
}

My first thought was to create UNCalendarNotificationTrigger on first fire date, than handle notification and set UNTimeIntervalNotificationTrigger, but unfortunately I cannot find the way to handle notification receive without user interaction.

Any thoughts how it should work?

As per the documentation if you want the notification to repeat you need to set repeatable constraints for the date components.

So to set a notification to run every morning at 8:30AM you would just set the hour and the minute and set it to repeat.

var date = DateComponents()
date.hour = 8
date.minute = 30 
let trigger = UNCalendarNotificationTrigger(dateMatching: date, repeats: true)

I don't think that you can use repeats to repeat every x number of days, you can set specific days of the week, or dates of the month, but not every n days.

You could set a TimeInterval of x number of days and repeat that, but getting the exact time to start it might be tricky.
