Using Date instead of NSDate: Answer taking from:

func timeAgoSinceDate(_ date:Date, numericDates:Bool = false) -> String {
    let calendar = NSCalendar.current
    let unitFlags: Set = [.minute, .hour, .day, .weekOfYear, .month, .year, .second]
    let now = Date()
    let earliest = now < date ? now : date
    let latest = (earliest == now) ? date : now
    let components = calendar.dateComponents(unitFlags, from: earliest,  to: latest)

    if (components.year! >= 2) {
        return "\(components.year!) years ago"
    } else if (components.year! >= 1){
        if (numericDates){
            return "1 year ago"
        } else {
            return "Last year"
        }
    } else if (components.month! >= 2) {
        return "\(components.month!) months ago"
    } else if (components.month! >= 1){
        if (numericDates){
            return "1 month ago"
        } else {
            return "Last month"
        }
    } else if (components.weekOfYear! >= 2) {
        return "\(components.weekOfYear!) weeks ago"
    } else if (components.weekOfYear! >= 1){
        if (numericDates){
            return "1 week ago"
        } else {
            return "Last week"
        }
    } else if (components.day! >= 2) {
        return "\(components.day!) days ago"
    } else if (components.day! >= 1){
        if (numericDates){
            return "1 day ago"
        } else {
            return "Yesterday"
        }
    } else if (components.hour! >= 2) {
        return "\(components.hour!) hours ago"
    } else if (components.hour! >= 1){
        if (numericDates){
            return "1 hour ago"
        } else {
            return "An hour ago"
        }
    } else if (components.minute! >= 2) {
        return "\(components.minute!) minutes ago"
    } else if (components.minute! >= 1){
        if (numericDates){
            return "1 minute ago"
        } else {
            return "A minute ago"
        }
    } else if (components.second! >= 3) {
        return "\(components.second!) seconds ago"
    } else {
        return "Just now"
    }

}

How to use

var createdDate : String = "123232323" //time stamp
var createdDataDisplayString: String {
    let date = Date(timeIntervalSince1970: Double(self.createdDate)!).timeAgoSinceDate(numericDates: true)
    return "\(date)"
}
print(self.createdDataDisplayString)
