Add circle to selected dates

[ghost]

So I have an array of dates. I want to add circle in the calendar, to the dates that is in the array. How can I do that? I know about this function below. But how can I add rings to all the dates in CalendarView that are equal to the dates in my array?:

func supplementaryView(shouldDisplayOnDayView dayView: DayView) -> Bool {
        guard let currentCalendar = currentCalendar else { return false }
        
        var components = Manager.componentsForDate(Foundation.Date(), calendar: currentCalendar)
        
        /* For consistency, always show supplementaryView on the 3rd, 13th and 23rd of the current month/year.  This is to check that these expected calendar days are "circled". There was a bug that was circling the wrong dates. A fix was put in for #408 #411.
         
         Other month and years show random days being circled as was done previously in the Demo code.
         */
        var shouldDisplay = false
        if dayView.date.year == components.year &&
            dayView.date.month == components.month {
            
            if (dayView.date.day == 3 || dayView.date.day == 13 || dayView.date.day == 23)  {
                print("Circle should appear on " + dayView.date.commonDescription)
                shouldDisplay = true
            }
        } else if (Int(arc4random_uniform(3)) == 1) {
            shouldDisplay = true
        }
        
        return shouldDisplay
    }

Fixed it by myself:

    func supplementaryView(shouldDisplayOnDayView dayView: DayView) -> Bool {
        guard let currentCalendar = currentCalendar else { return false }
        
        let day = dayView.date.convertedDate()
        
        var shouldDisplay = false
        let val = result.filter { compareDate(date1:$0.date!, date2:day!) }
        if val.isEmpty == false {
            shouldDisplay = true
        }
        
        return shouldDisplay
    }
