What it is
SwifterSwift is a collection of more than 500 Swift extensions, which are small added methods for built-in types like strings, arrays, and UIKit or Cocoa classes. It is meant to save developers from writing the same helper code again and again across iOS, macOS, tvOS, watchOS, Linux, and Android projects.
- Add string, date, or collection helper methods to an existing iOS app without writing them yourself
- Include only the UIKit or CoreLocation extensions in a project using CocoaPods
- Add the library as a Swift Package dependency and call its extensions from your own code
Great for
- Swift developers building iOS or macOS apps who want common helper methods ready to use
- Teams that want to pick only the extension groups they need, such as UIKit or CoreLocation
- Developers who prefer Swift Package Manager, CocoaPods, or Carthage for dependencies
Not ideal for
- Beginners still learning Swift basics, since the library assumes you can read and call extensions yourself
- Projects that must support Swift versions older than the ones listed in the requirements, because the README points to older tagged releases instead
- Anyone who wants a full app or framework rather than a set of helper methods
How to get it
- 1
Install with a package manager
You'll need: Xcode with Swift 6.0+ support · Swift Package Manager, CocoaPods, or Carthage, depending on your setup
CocoaPods: add to Podfile (all extensions)
pod 'SwifterSwift'Carthage: add to Cartfile
github "SwifterSwift/SwifterSwift" ~> 6.0 - 2
Run it
- Choose an installation method from the README, such as CocoaPods, Carthage, or Swift Package Manager.
- Add the dependency line to your Podfile, Cartfile, or Package.swift file.
- Run pod install, or update your package dependencies in Xcode or with the Swift package manager.
- Import SwifterSwift in a Swift file and call one of its extensions to confirm it works.

Get the most out of it
- Import only the modules you need, such as UIKit or CoreLocation, to keep the integration smaller
- Browse the List of All Extensions section in the README to find helpers for your types
- Use the Swift Package Manager integration with the from: "6.0.0" version line for a stable starting point
- Check the CHANGELOG for version-specific changes before upgrading
Downloads
Strengths
- Covers a large range of types, with more than 500 extensions organized by module
- Supports several dependency managers, including Swift Package Manager, CocoaPods, Carthage, and Accio
- Licensed under MIT, which allows free use in commercial projects
Trade-offs
- Helper methods add to your dependency footprint, and you should check each one fits your needs
- Requirements are fairly recent, such as iOS 15.0+ and Swift 6.0+, so older projects may not be able to upgrade easily
- The README is truncated here, so details of individual extensions and the latest release notes were not verified
