struct CalendarCalendar encapsulates information about systems of reckoning time in which the beginning, length, and divisions of a year are defined. It provides information about the calendar and support for calendrical computations such as determining the range of a given calendrical unit and adding units to a given absolute time.

var calendar: CalendarThe calendar in which the recurrence occurs
var daysOfTheMonth: [Int]On which days in the month the event should occur
var daysOfTheYear: [Int]On which days of the year the event may occur.
var end: Calendar.RecurrenceRule.EndFor how long the event repeats
var frequency: Calendar.RecurrenceRule.FrequencyHow often the event repeats
var hours: [Int]On which hours of a 24-hour day the event should repeat.
var interval: IntAt what interval to repeat
var matchingPolicy: Calendar.MatchingPolicyWhat to do when a recurrence is not a valid date
var minutes: [Int]On which minutes of the hour the event should repeat. Accepts values between 0 and 59
var months: [Calendar.RecurrenceRule.Month]On which months the event should occur.
var repeatedTimePolicy: Calendar.RepeatedTimePolicyWhat to do when there are multiple recurrences occurring at the same time of the day but in different time zones due to a daylight saving transition.
var seconds: [Int]On which seconds of the minute the event should repeat. Valid values between 0 and 60
var setPositions: [Int]Which occurrences within every interval should be returned
var weekdays: [Calendar.RecurrenceRule.Weekday]On which days of the week the event should occur
var weeks: [Int]On which weeks of the year the event should occur.
