Change your text as you want.

extension NSDate {

    func getElapsedInterval() -> String {

        var interval = NSCalendar.currentCalendar().components(.Year, fromDate: self, toDate: NSDate(), options: []).year

        if interval > 0 {
            return interval == 1 ? "\(interval)" + " " + "year" :
            "\(interval)" + " " + "years"
        }

        interval = NSCalendar.currentCalendar().components(.Month, fromDate: self, toDate: NSDate(), options: []).month
        if interval > 0 {
            return interval == 1 ? "\(interval)" + " " + "month" :
            "\(interval)" + " " + "months"
        }

        interval = NSCalendar.currentCalendar().components(.Day, fromDate: self, toDate: NSDate(), options: []).day
        if interval > 0 {
            return interval == 1 ? "\(interval)" + " " + "day" :
            "\(interval)" + " " + "days"
        }

        interval = NSCalendar.currentCalendar().components(.Hour, fromDate: self, toDate: NSDate(), options: []).hour
        if interval > 0 {
            return interval == 1 ? "\(interval)" + " " + "hour" :
            "\(interval)" + " " + "hours"
        }

        interval = NSCalendar.currentCalendar().components(.Minute, fromDate: self, toDate: NSDate(), options: []).minute
        if interval > 0 {
            return interval == 1 ? "\(interval)" + " " + "minute" :
            "\(interval)" + " " + "minutes"
        }

        return "a moment ago"
    }
}
