Swift 3 version of truongky's code:

extension Date {

    var timeAgoSinceNow: String {
        return getTimeAgoSinceNow()
    }

    private func getTimeAgoSinceNow() -> String {

        var interval = Calendar.current.dateComponents([.year], from: self, to: Date()).year!
        if interval > 0 {
            return interval == 1 ? "\(interval)" + " year" : "\(interval)" + " years"
        }

        interval = Calendar.current.dateComponents([.month], from: self, to: Date()).month!
        if interval > 0 {
            return interval == 1 ? "\(interval)" + " month" : "\(interval)" + " months"
        }

        interval = Calendar.current.dateComponents([.day], from: self, to: Date()).day!
        if interval > 0 {
            return interval == 1 ? "\(interval)" + " day" : "\(interval)" + " days"
        }

        interval = Calendar.current.dateComponents([.hour], from: self, to: Date()).hour!
        if interval > 0 {
            return interval == 1 ? "\(interval)" + " hour" : "\(interval)" + " hours"
        }

        interval = Calendar.current.dateComponents([.minute], from: self, to: Date()).minute!
        if interval > 0 {
            return interval == 1 ? "\(interval)" + " minute" : "\(interval)" + " minutes"
        }

        return "a moment ago"
    }
