Try Below Code :-

        let calendar = NSCalendar(calendarIdentifier:NSCalendarIdentifierGregorian)
        calendar?.timeZone =  NSTimeZone(abbreviation: "GMT")!
        let startOfDay = calendar?.startOfDayForDate(sender.date)

        print("startDay \(startOfDay)")
        let components = NSDateComponents()
        components.hour   = 23
        components.minute = 59
        components.second = 59
        components.timeZone =  NSTimeZone(abbreviation: "GMT")

        let endOfDay = calendar?.dateByAddingComponents(components, toDate: startOfDay!, options: NSCalendarOptions(rawValue: 0))
        print("end Day \(endOfDay)")
