A quick and dirty way to get an approximate, relative date from a date.

quickRelativeDate.swift

import Foundation

extension Date {
    func quickRelativeTime() -> String {
        let then = self.timeIntervalSince1970
        let now = Date().timeIntervalSince1970
        
        let seconds = now - then
        if seconds < 0 { return "Sometime in the future..." }
        
        let minutes = round(seconds/60)
        let hours = round(minutes/60)
        let days = round(hours/24)
        let weeks = round(days/7)
        let months = round(days/30)
       
        if seconds < 10 { return "Just now" } else if seconds < 60 { return "\(Int(seconds)) seconds ago" }
        
        if minutes < 60 {
            if minutes == 1 { return "A minute ago" } else { return "\(Int(minutes)) minutes ago" }
        }
        
        if hours < 24 {
            if hours == 1 { return "An hour ago" } else { return "\(Int(hours)) hours ago" }
        }
        
        if days < 7 {
            if days == 1 { return "A day ago" } else { return "\(Int(days)) days ago" }
        }
        
        if weeks < 4 {
            if weeks == 1 { return "A week ago" } else { return "\(Int(weeks)) weeks ago" }
        }
        
        if months < 12 {
            if months == 1 { "A month ago" } else { return "\(Int(months)) months ago" }
        }
        
        return "More than a year ago"
    }
    
}

let date = Date(timeIntervalSince1970: 1488683746)
print (date)
print(date.quickRelativeTime())

// 2017-03-05 03:15:46 +0000
// A week ago
