SwifterSwift is a collection of over 500 native Swift extensions, with handy methods, syntactic sugar, and performance improvements for wide range of primitive data types, UIKit and Cocoa classes –over 500 in 1– for iOS, macOS, tvOS, watchOS and Linux.


Whats New in v5.3?


  • iOS 10.0+ / tvOS 9.0+ / watchOS 2.0+ / macOS 10.10+ / Ubuntu 14.04+
  • Swift 5.0+

Looking to use SwifterSwift for older versions of Swift

SwifterSwift is Swift v5.0+ compatible starting from v5

  • To use with Swift 3 / Xcode 8.x please ensure you are using v3.1.1.
  • To use with Swift 3.2 / Xcode 9.x please ensure you are using v3.2.0.


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

- Integrate All extensions (recommended): pod 'SwifterSwift'

- Integrate SwiftStdlib extensions only: pod 'SwifterSwift/SwiftStdlib'

- Integrate Foundation extensions only: pod 'SwifterSwift/Foundation'

- Integrate UIKit extensions only: pod 'SwifterSwift/UIKit'

- Integrate AppKit extensions only: pod 'SwifterSwift/AppKit'

- Integrate MapKit extensions only: pod 'SwifterSwift/MapKit'

- Integrate CoreGraphics extensions only: pod 'SwifterSwift/CoreGraphics'

- Integrate CoreLocation extensions only: pod 'SwifterSwift/CoreLocation'

- Integrate CryptoKit extensions only: pod 'SwifterSwift/CryptoKit'

- Integrate SpriteKit extensions only: pod 'SwifterSwift/SpriteKit'

- Integrate SceneKit extensions only: pod 'SwifterSwift/SceneKit'

- Integrate StoreKit extensions only: pod 'SwifterSwift/StoreKit'

- Integrate Dispatch extensions only: pod 'SwifterSwift/Dispatch'

- Integrate WebKit extensions only: pod 'SwifterSwift/WebKit'

- Integrate HealthKit extensions only: pod 'SwifterSwift/HealthKit'

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

github "SwifterSwift/SwifterSwift" ~> 5.3

Swift Package Manager You can use The Swift Package Manager to install SwifterSwift by adding the proper description to your Package.swift file:

import PackageDescription

let package = Package( name: "YOUR_PROJECT_NAME", targets: [], dependencies: [ .package(url: "https://github.com/SwifterSwift/SwifterSwift.git", from: "5.3.0") ] )

Next, add SwifterSwift to your targets dependencies like so: .target( name: "YOUR_TARGET_NAME", dependencies: [ "SwifterSwift", ] ), Then run swift package update.

Note that the Swift Package Manager doesn't support building for iOS/tvOS/macOS/watchOS apps – see Accio in the next section for that.

Accio Accio is a dependency manager based on SwiftPM which can build frameworks for iOS/macOS/tvOS/watchOS. Therefore the integration steps are exactly the same as described above. Once your Package.swift file is configured, you need to run accio update instead of swift package update though.

Manually Add the SwifterSwift folder to your Xcode project to use all extensions, or a specific extension. For your test targets you can also add the XCTest folder.
