You need to add this date extension in your helper class or any in swift file. Swift 4.2 . if you want in swift 3 just uncomment the commented line and comment the next line.

And call the method as follow:

 let dateText = Date().offsetFrom(date: yourDate!)

yourDate is date that to be change

////MARK: *************** Extension Date ***************
 extension Date{


func convertToString(validDateFormatter:String) -> String {
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = validDateFormatter //"dd MMM yyyy" //yyyy-mm-dd hh:mm
    //return dateFormatter.stringFromDate(self)
    return dateFormatter.string(from: self as Date)

}

func yearsFrom(date:Date) -> Int{
    //        return NSCalendar.currentCalendar.components(.Year, fromDate: date, toDate: self, options: []).year
    //        let calendar = NSCalendar.current

    //        let components = Calendar.current.dateComponents([.year], from: date, to: self as Date)

    return Calendar.current.dateComponents([.year], from: date, to: self).year!

}
func monthsFrom(date:Date) -> Int{
    //        return NSCalendar.currentCalendar.components(.Month, fromDate: date, toDate: self, options: []).month
    return Calendar.current.dateComponents([.month], from: date as Date, to: self).month!
}
func weeksFrom(date:Date) -> Int{
    //return NSCalendar.currentCalendar.components(.WeekOfYear, fromDate: date, toDate: self, options: []).weekOfYear
    return Calendar.current.dateComponents([.weekOfYear], from: date, to: self).weekOfYear!
}
func daysFrom(date:Date) -> Int{
    //        return NSCalendar.currentCalendar.components(.Day, fromDate: date, toDate: self, options: []).day
    return Calendar.current.dateComponents([.day], from: date, to: self).day!
}
func hoursFrom(date:Date) -> Int{
    //        return NSCalendar.currentCalendar.components(.Hour, fromDate: date, toDate: self, options: []).hour
    return Calendar.current.dateComponents([.hour], from: date, to: self).hour!
}
func minutesFrom(date:Date) -> Int{
    //        return NSCalendar.currentCalendar.components(.Minute, fromDate: date, toDate: self, options: []).minute
    return Calendar.current.dateComponents([.minute], from: date, to: self).minute!
}
func secondsFrom(date:Date) -> Int{
    //        return NSCalendar.currentCalendar.components(.Second, fromDate: date, toDate: self, options: []).second
    return Calendar.current.dateComponents([.second], from: date, to: self).second!
}
func offsetFrom(date:Date) -> String
{
    if yearsFrom(date: date) > 0 {
        return "\(yearsFrom(date: date))y"
    }
    if monthsFrom(date: date) > 0 {
        return "\(monthsFrom(date: date))M"
    }
    if weeksFrom(date: date) > 0{
        return "\(weeksFrom(date: date))w"
    }
    if daysFrom(date: date) > 0 {
        return "\(daysFrom(date: date))d"
    }
    if hoursFrom(date: date) > 0 {
        return "\(hoursFrom(date: date))h"
    }
    if minutesFrom(date: date) > 0 {
        return "\(minutesFrom(date: date))m"
    }
    if secondsFrom(date: date) > 0 {
        return "\(secondsFrom(date: date))s"
    }
    return ""

}
