Carthage compatible CI Status Version License Platform

We really ♥ Swift and we think that dates and timezones management should be painless: this is the reason we made SwiftDate, probably the best way to manage date and time in Swift.

Choose SwiftDate for your next project, or migrate over your existing projects—you'll be happy you did! 4.1.

Main features

Here's a highlight of the main features you can find in SwiftDate:

  • Simple math operations with dates! Example: aDate + 2.weeks + 1.hour or (1.year - 2.hours + 16.minutes).fromNow()
  • Easy conversions to and from timezone, locale and calendar. Use the helper class DateInRegion and perform conversions with components and operations!
  • Compare dates with math operators <,>,==,<=,>=. For example, you can do aDate1 >= aDate2 or aDate1.isIn(anotherDate,.day)
  • Easily work with time components. E.g. aDateInRegion.day or hour, minutes etc. expressed in your favourite timezone!
  • Easy and optimized way to get and transform a date from and to strings: supports both colloquial (human readable) and fixed formats (ISO8601, AltRSS, RSS, Extended, .NET and custom string as per Unicode standard)
  • Express time interval in other time units; for example 120.seconds.in(.minutes) // 2 minutes
  • Many shortcuts to get intervals, work with time units, intervals and common date operations (isYesterday,isTomorrow,isBefore()...)
  • ... many many other shiny things!

SwiftDate supports multiple methods for installing the library in a project.

Installation with CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like SwiftDate in your projects. You can install it with the following command:

$ gem install cocoapods

CocoaPods 1.0.1+ is required to build SwiftDate 4+ (along with Swift 3 and Xcode 8).


To integrate SwiftDate into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'

target 'TargetName' do
  pod 'SwiftDate', '~> 4.0'

(use 4.0.13 for Swift 3.0)

Then, run the following command:

$ pod install

Installation with Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate SwiftDate into your Xcode project using Carthage, specify it in your Cartfile:

github "malcommac/SwiftDate" ~> 4.0

Run carthage to build the framework and drag the built SwiftDate.framework into your Xcode project.


Current version is compatible with:

  • Swift 3.1 (4.0.13 is the latest version compatibile with Swift 3)
  • iOS 8 or later
  • macOS 10.10 or later
  • watchOS 2.0 or later
  • tvOS 9.0 or later
  • ...and virtually any platform which is compatible with Swift 3 and implements the Swift Foundation Library

Are you searching for an old (unsupported) SwiftDate version? Check out:
