Swift – The beginning of the week and end day last week

< /p>

let cal = NSCalendar.currentCalendar()

let components = NSDateComponents()
components.weekOfYear -= 1
< br />if let date = cal.dateByAddingComponents(components, toDate: NSDate(), options: NSCalendarOptions(0)) {
 var beginningOfWeek: NSDate?
 var weekDuration = NSTimeInterval()
 if cal.rangeOfUnit(.CalendarUnitWeekOfYear, startDate: &beginningOfWeek, interval: &weekDuration, forDate: date) {
 let endOfWeek = beginningOfWeek?.dateByAddingTimeInterval(weekDuration)
 print(beginningOfWeek) // Optional(2015-02 -15 05:00:00 +0000)
 print(endOfWeek) // Optional(2015-02-22 05:00:00 +0000)
 }
}

Today is Friday, March 6. How to find that February 16 is the start day, and February 22 is the end day of the week before the previous week.
16 is my country, Bulgaria In the U.S. it will be 15 and 21 I use.curren tCalendar()

Things like this should work:

let cal = NSCalendar.currentCalendar()

let components = NSDateComponents()
components.weekOfYear -= 1

if let date = cal.dateByAddingComponents(components, toDate: NSDate(), options: NSCalendarOptions( 0)) {
 var beginningOfWeek: NSDate?
 var weekDuration = NSTimeInterval()
 if cal.rangeOfUnit(.CalendarUnitWeekOfYear, startDate: &beginningOfWeek, interval: &weekDuration, forDate: date) {
 let endOfWeek = beginningOfWeek?.dateByAddingTimeInterval(weekDuration)
 print(beginningOfWeek) // Optional(2015-02-15 05:00:00 +0000)
 print(endOfWeek) // Optional(2015 -02-22 05:00:00 +0000)
 }
}
