Current Week Start and End Date

Question

I want to get the current week start and end date and I also want to use the previous week start and end date and next week of the start and end date in current month.

Answer 1

A Swift version

of vikingosegundo's answer:

let calendar = NSCalendar.currentCalendar()
var startOfTheWeek: NSDate?
var endOfWeek: NSDate!
var interval = NSTimeInterval(0)

calendar.rangeOfUnit(.WeekOfMonth, startDate: &startOfTheWeek, interval: &interval, forDate: NSDate())
endOfWeek = startOfTheWeek!.dateByAddingTimeInterval(interval - 1)
