Here is a solution you can copy paste

 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!)yr"
    } else if (components.year! >= 1){
        if (numericDates){
            return "1yr"
        } else {
            return "Last year"
        }
    } else if (components.month! >= 2) {
        return "\(components.month!)mo"
    } else if (components.month! >= 1){
        if (numericDates){
            return "1 mo"
        } else {
            return "Last mo"
        }
    } else if (components.weekOfYear! >= 2) {
        return "\(components.weekOfYear!) weeks"
    } else if (components.weekOfYear! >= 1){
        if (numericDates){
            return "1 week"
        } else {
            return "Last week"
        }
    } else if (components.day! >= 2) {
        return "\(components.day!) d"
    } else if (components.day! >= 1){
        if (numericDates){
            return "1 d"
        } else {
            return "1 d"
        }
    } else if (components.hour! >= 2) {
        return "\(components.hour!) hrs"
    } else if (components.hour! >= 1){
        if (numericDates){
            return "1 hr"
        } else {
            return "1 hr"
        }
    } else if (components.minute! >= 2) {
        return "\(components.minute!) m"
    } else if (components.minute! >= 1){
        if (numericDates){
            return "1 m"
        } else {
            return "2 m"
        }
    } else if (components.second! >= 3) {
        return "\(components.second!)s"
    } else {
        return "now"
    }

}

to call, simply use

    // the date you are getting information about 
let dateToReference = Date()
            if let timeAgo = timeAgoSinceDate(dateToReference) {
                //will be a String value
                print(timeAgo)

            } else {
                //just in case something goes wrong
                print("recently")

            }
