        let selector = UIStoryboard(name: "WWCalendarTimeSelector", bundle: nil).instantiateInitialViewController() as! WWCalendarTimeSelector
        selector.delegate = self
        selector.optionCurrentDate = singleDate
        selector.optionCurrentDates = Set(multipleDates)
        selector.optionCurrentDateRange.setStartDate(multipleDates.first ?? singleDate)
        selector.optionCurrentDateRange.setEndDate(multipleDates.last ?? singleDate)

        selector.optionStyles.showDateMonth(true)
        selector.optionStyles.showMonth(false)
        selector.optionStyles.showYear(true)
        selector.optionStyles.showTime(false)
        present(selector, animated: true, completion: nil)
    }
 func WWCalendarTimeSelectorDone(_ selector: WWCalendarTimeSelector, date: Date) {
        print("Selected \n\(date)\n---")
        singleDate = date
        dateLabel.text = date.stringFromFormat("d' 'MMMM' 'yyyy', 'h':'mma")
    }

    func WWCalendarTimeSelectorDone(_ selector: WWCalendarTimeSelector, dates: [Date]) {
        print("Selected Multiple Dates \n\(dates)\n---")
        if let date = dates.first {
            singleDate = date
            dateLabel.text = date.stringFromFormat("d' 'MMMM' 'yyyy', 'h':'mma")
        }
        else {
            dateLabel.text = "No Date Selected"
        }
        multipleDates = dates
    }

You need to use WWCalendarTimeSelectorShouldSelectDate method for disabling the dates/date range you need. The below example may help you

    fileprivate var today: Date = Date()

    func WWCalendarTimeSelectorShouldSelectDate(_ selector: WWCalendarTimeSelector, date: Date) -> Bool{
        let order = NSCalendar.current.compare(today, to: date, toGranularity: .day)
        if order == .orderedDescending{ {
            //Date selection will be disabled for past days
            return false
        } else {
            //Allows to select from today
            return true
        }
    }

You can use your own date range in the above example
