FSCalendar jumps to year 1970

Question

I'm trying to reload FSCalendar using Dispatch main queue. it works fine but it causes the calendar to jump all the way back to 1970 how can i prevent this from happening? or set the date to current date again ? here is my code:

DispatchQueue.main.async {

    self.calendar.firstWeekday = 7
    self.calendar.locale = Locale(identifier: "fa_IR")
    self.calendar.select(Date())
    self.calendar.identifier = NSCalendar.Identifier.persian.rawValue
    self.calendar.reloadData()
}

btw this issue has nothing to do with Dispatch. reloading it in other forms causes the same problem too.

I've never used `FSCalendar`, but are you sure, `calendar.reloadData()` shouldn't happen after you change the data? To me it seems like the logical approach to first change the data, then reload the calendar. — Dávid Pásztor, Sep 18 '17 at 19:26
@DávidPásztor tried that. Unfortunately, it doesn't fix the problem, — Farbod, Sep 18 '17 at 19:30
A date in 1970 typically indicates that the actual date timestamp has been set to 0, or is missing. I haven't used FSCalendar but I'd check that it's getting a nonzero date value. — Tom Harrington, Sep 18 '17 at 19:30
@TomHarrington that's not the case here. if that was the problem the calendar should still have problems when I remove reloadData(). but that doesn't happen — Farbod, Sep 18 '17 at 19:35
@Farbod unless it's happening as a side-effect of calling `reloadData`. — Tom Harrington, Sep 18 '17 at 19:37

For current date you have to first get current month position. For that you must add two method of FSCalendarDelegate

func calendar(_ calendar: FSCalendar, shouldSelect date: Date, at monthPosition: FSCalendarMonthPosition)   -> Bool {
    return monthPosition == .current
}

func calendar(_ calendar: FSCalendar, shouldDeselect date: Date, at monthPosition: FSCalendarMonthPosition) -> Bool {

    return monthPosition == .current
}

Hope this will help you.
