This works for iOS 13 / Swift 5. Credit goes to Sourabh Sharma

func timeAgoSinceNow(numericDates: Bool = true) -> String {
    let calendar = Calendar.current
    let now = Date()
    let earliest = (now as NSDate).earlierDate(self)
    let latest = (earliest == now) ? self : now
    let components: DateComponents = (calendar as NSCalendar).components([NSCalendar.Unit.minute,
                                                                          NSCalendar.Unit.hour,
                                                                          NSCalendar.Unit.day,
                                                                          NSCalendar.Unit.weekOfYear,
                                                                          NSCalendar.Unit.month,
                                                                          NSCalendar.Unit.year,
                                                                          NSCalendar.Unit.second],
                                                                         from: earliest,
                                                                         to: latest,
                                                                         options: NSCalendar.Options())

    guard
        let year = components.year,
        let month = components.month,
        let weekOfYear = components.weekOfYear,
        let day = components.day,
        let hour = components.hour,
        let minute = components.minute,
        let second = components.second
    else { return "A while ago"}

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

Usage:

var date = Date() // Or any date you wish to convert to text
print("\(date.timeAgoSinceNow())") // "Just Now"
