Why doesn't iOSNotificationCalendarTrigger have a weekday property?

Hello everyone

I am trying to implement a weekly notification function with this library, but the Calendar Trigger does not have a day of the week property, so I am considering how to achieve this.

In the near future, I am planning to implement a pseudo-weekly event firing by directly specifying the date and time on the calendar and implementing it with a Time IntervalTrigger, but looking at Apple's documentation, it seems that there is support for this on the OS side, so I wrote this issue as I thought it would be useful if I could do this.

iOS's NSDateComponents implements the weekday property, which allows you to implement weekly notifications.
If you pass it to UNCalendarNotificationTrigger, you can easily implement weekly notifications, which is very helpful...

A randomly written snippet..

        NSDateComponents* date = [[NSDateComponents alloc] init];
        if (data->trigger.calendar.year >= 0)
            date.year = data->trigger.calendar.year;
        if (data->trigger.calendar.month >= 0)
            date.month = data->trigger.calendar.month;
        if (data->trigger.calendar.day >= 0)
            date.day = data->trigger.calendar.day;
        if (data->trigger.calendar.hour >= 0)
            date.hour = data->trigger.calendar.hour;
        if (data->trigger.calendar.minute >= 0)
            date.minute = data->trigger.calendar.minute;
        if (data->trigger.calendar.second >= 0)
            date.second = data->trigger.calendar.second;
        if(data->trigger.calendar.weekday >=1 && trigger.calendar.weekday <8)
            date.weekday = data->trigger.calendar.weekday;
