Hi, do you think we could have a version for Swift 3 ? Thx

msamoylov · 2016-09-19T20:05:54Z

@sebastienboulogne here you go, ported to Swift 3.

Great,
Thanks guys for the efforts .Thats why I love gist will surely start contributing as much as possible soon .

Thanks Man, awesome code.

Sweet!

I made a Swift 3 framework for this. Has support for CocoaPods, Carthage, SPM, all platforms (iOS, macOS, tvOS, watchOS), and 42 localizations. Check it out and let me know what you think! https://github.com/toddkramer/LocalizedTimeAgo

Using Date instead of NSDate:

func timeAgoSinceDate(_ date:Date, numericDates:Bool = false) -> String {

        let unitFlags: Set<Calendar.Component> = [.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!) years ago"
        } else if (components.year! >= 1){
            if (numericDates){
                return "1 year ago"
            } else {
                return "Last year"
            }
        } else if (components.month! >= 2) {
            return "\(components.month!) months ago"
        } else if (components.month! >= 1){
            if (numericDates){

        } else if (components.weekOfYear! >= 1){
            if (numericDates){
                return "1 week ago"
            } else {
                return "Last week"

            } else {
                return "An hour ago"
            }
        } else if (components.minute! >= 2) {
            return "\(components.minute!) minutes ago"
        } else if (components.minute! >= 1){

thank you, guys!

MHX792 · 2017-02-17T16:26:03Z

@heinrisch let calendar = NSCalendar.current should be changed to let calendar = Calendar.current otherwise the month, year, week components were 0 for me.

I rewrote this to be more swift-y because I needed future dates as well. Naming could be better I guess

Golden. Thanks for the time saver.

If anyone found themselves here and needed usage:



if let timeAgo = timeAgoSinceDate(yourInfoAsDateFormat) {
                    
                   yourLabel.text = timeAgo

Sorry for interrupting the party, but seems like "time ago" feature is implemented in DateTools with locales and just works:
https://github.com/MatthewYork/DateTools#time-ago

let timeAgoDate = 2.days.earlier
print("Time Ago: ", timeAgoDate.timeAgoSinceNow)
print("Time Ago: ", timeAgoDate.shortTimeAgoSinceNow)

//Output:
//Time Ago: 2 days ago
//Time Ago: 2d

dariukas · 2018-08-16T19:25:42Z

The framework looks nice. However, sometimes only a feature is needed, not the whole framework = why to buy the whole cow if you need only milk.
