Answer 1

In Swift 2, use extension to extend NSDate:

extension NSDate {

    func addDays(days:Int) -> NSDate{
        let newDate = NSCalendar.currentCalendar().dateByAddingUnit(
            .Day,
            value: days,
            toDate: self,
            options: NSCalendarOptions(rawValue: 0))

        return newDate!
    }
}
