calendarView setAvailableDates function taking long time to load calendar view

[seekingdesti]

Hi,

I have 5 years dates in calendar, it's taking very long time to load calendar view.
I i am using below function to load 5 years dates.

let avlblDates = datesRange(from: 01.01.2019, to: Date())
calendarView.setAvailableDates(DaysAvailability.some(avlblDates))

private func datesRange(from: Date, to: Date) -> [Date] {
if from > to { return Date }
var tempDate = from
var array = [tempDate]

    while tempDate < to {
        tempDate = Calendar.current.date(byAdding: .day, value: 1, to: tempDate)!
        array.append(tempDate)
    }
    return array
}


Please help me on this as it takes upto 10 seconds to load calendar view.

Thanks.

• go to VACalendar.swift file

• find setDaysAvailability method and update it like below

  func setDaysAvailability(_ availability: DaysAvailability) {
  daysAvailability = availability

    switch availability {
    case .all:
        let days = months.flatMap { $0.allDays() }
        days.forEach { $0.setState(.available) }
        
    case .some(let dates):
        let allDays = months.flatMap { $0.allDays() }
        //allDays.forEach { $0.setState(.unavailable) }
        //let availableDays = dates.flatMap { date in allDays.filter { $0.dateInDay(date) }}
        //availableDays.forEach { $0.setState(.available) }
        //let availableDatesSet = Set(dates)
        let availableDatesSet = Set(dates.map { normalizeToMidnight(date: $0) })
        availableDatesSet.forEach { print($0) }
        allDays.forEach { day in
            let dayStartDate = normalizeToMidnight(date: day.date)
            if availableDatesSet.contains(dayStartDate) {
                day.setState(.available)
            } else {
                day.setState(.unavailable)
            }
        }
    }
  

  }
  func normalizeToMidnight(date: Date) -> Date {
  var calendar = Calendar.current
  calendar.timeZone = TimeZone(secondsFromGMT: 0)! // Ensure the time zone is UTC
  return calendar.startOfDay(for: date)
  }
