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) }
