Swift display time ago from Date (NSDate)

Question

In a cell I want to display the time ago from the NSDate in the Parse server. Here is the code but its not working. Nothing is changing, and the data isn't being parsed.

    if let createdat = (object?["createdAt"] as? String){
            let pastDate = Date(timeIntervalSinceNow: TimeInterval(createdat)!)
            cell.TimeAgo.text = pastDate.timeAgoDisplay()
        }


       extension Date {
          func timeAgoDisplay() -> String {
        let secondsAgo = Int(Date().timeIntervalSince(self))

        let minute = 60
        let hour = 60 * minute
        let day = 24 * hour
        let week = 7 * day

        if secondsAgo < minute {
            return "\(secondsAgo) sec ago"
        } else if secondsAgo < hour {
            return "\(secondsAgo / minute) min ago"
        } else if secondsAgo < day {
            return "\(secondsAgo / hour) hrs ago"
        } else if secondsAgo < week {
            return "\(secondsAgo / day) days ago"
        }

        return "\(secondsAgo / week) weeks ago"
    }
}

Pass time as String in format e.g. 2019-02-25 10:20:21 Pass dateformat in Variable dateFormat

let dateFormat = "yyyy-MM-dd HH:mm:ss"

    func timeInterval(timeAgo:String) -> String
        {
            let df = DateFormatter()

            df.dateFormat = dateFormat
            let dateWithTime = df.date(from: timeAgo)

            let interval = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute, .second], from: dateWithTime!, to: Date())

            if let year = interval.year, year > 0 {
                return year == 1 ? "\(year)" + " " + "year ago" : "\(year)" + " " + "years ago"
            } else if let month = interval.month, month > 0 {
                return month == 1 ? "\(month)" + " " + "month ago" : "\(month)" + " " + "months ago"
            } else if let day = interval.day, day > 0 {
                return day == 1 ? "\(day)" + " " + "day ago" : "\(day)" + " " + "days ago"
            }else if let hour = interval.hour, hour > 0 {
                return hour == 1 ? "\(hour)" + " " + "hour ago" : "\(hour)" + " " + "hours ago"
            }else if let minute = interval.minute, minute > 0 {
                return minute == 1 ? "\(minute)" + " " + "minute ago" : "\(minute)" + " " + "minutes ago"
            }else if let second = interval.second, second > 0 {
                return second == 1 ? "\(second)" + " " + "second ago" : "\(second)" + " " + "seconds ago"
            } else {
                return "a moment ago"

            }
        }
