The site also accepts contributions if you know of a great library that's not currently featured.

SwiftFormat

A code library and command line tool for reformatting Swift code. SwiftFormat can be added to your project as a Build Phase or run manually from the command line. It applies a set of rules to the whitespace around the code, while leaving the meaning intact, making it great for enforcing a common coding style. It already supports a huge list of rules including spacing around parentheses, brackets and braces, line breaks around scope, semicolons, and more with additional rules planned in a future update.

Redbeard

Redbeard includes a number of UI features including forms, a several different extensible layouts, and UI containers such as sidebars and panes. The theming engine allows your app UI to be completely rebranded with minimal code changes, and an ORM, REST client, Network Centre and a number of other helpers and extension methods make dealing with data and networking much easier.

LayoutKit

A view layout library for iOS written in Swift by the developers at LinkedIn. LayoutKit was created because the LinkedIn developers found that Auto Layout is not performant enough for complicated view hierarchies in scrollable views. It aims to be as fast as manual layout code and allows layouts to be computed on a background thread so user interactions are not interrupted. It works seamlessly with UIKit and utilises several modern Swift patterns including declarative layouts that make it easier to develop, document, code review, test, debug, profile, and maintain.

Taylor

A tool that aims to improve Swift code quality, by checking for conformance of code metrics. Unlike similar linting tools, Taylor focuses on more subjective code quality metric by providing warnings for rules such as excessive class or method length, too many overly complicated methods, excessive block depth or too many method parameters. It can be run independently from the command line on a single file or a complete project, or you can add a build phase to add warnings to Xcode.

json2swift

A macOS command line tool that generates Swift data model code based on JSON data. json2swift generates immutable Swift struct definitions along with thread-safe initialisers to create structs from JSON data. It performs sophisticated type inference to detect data types such as URLs and dates. For example, if you add a date format hint to your JSON, it will correctly add string to date parsing. It also aims to provide the correct optionality, making properties non-optional unless 'null' is found in the JSON.

xcute

A simple Python command line tool for understanding Xcode project structures and configurations. xcute will inspect an Xcode project file and print a table detailing each of the Xcode schemes including SDK and configuration. You can also provide flags to get details about any build setting across all your schemes, which could be useful for quickly checking provisioning settings, for example. It can also export CI config files using a built-in template for Travis or any other custom template you create.

Depcheck

A dependency analyser tool for Swift projects. Depcheck reports dependencies per class, allowing you to easily detect classes that have too many dependencies. It can also report how many dependants a class have making it easy to spot the most over-used and under-used classes. It supports Xcode projects and workspaces so works great if you are using cocoapods.

imsticker

A small command line tool that makes it quick and easy to create an Xcode project for an iOS 10 sticker pack. imsticker saves you a lot of clicks by giving your a single command to automate the entire process of creating an Xcode project, adding sticker images including animated sequences, and creating all the required icons. You just need to prepare your sticker images and large app icon in a folder, and imsticker will create the project ready for you to open, run and submit to the App Store.

Documentation

jazzy

A command-line tool for generating documentation for Swift and Objective-C. jazzy goes beyond just parsing source files by actually using SourceKit and the Clang AST representation of your code and its comments to generate more accurate results. The generated output is clear, simple to navigate, matches the look and feel of Apple’s official reference documentation and can even be installed in the popular Dash documentation viewer.

SwiftDoc.org

Complete online auto-generated documentation for Swift. SwiftDoc.org provides a way to easily browse all the types, protocols, operators and globals that are defined internally to the language without having to command-click around header files in Xcode. It is entirely generated from the Swift header file so documentation pages include everything from initializers and instance methods to variables and inheritance. Where relevant, inheritance hierarchy graphs show all the protocols that a type conforms to, or all the types that conform to a protocol.

Dash API Docs

The popular OS X documentation viewer is now available on iPhone and iPad. Dash is an API documentation browser that gives your iPad and iPhone instant offline access to over 150 API documentation sets including iOS, Swift and many others covering web technologies, popular third party libraries, databases and more. You can also import any other docsets generated using popular tools like Appledoc and Doxygen using iTunes. Navigating the docsets is easy and fast thanks to full fuzzy search and complete table of contents.

appledoc

An Objective-C API documentation generator that creates Apple-like source code documentation from specially formatted source code comments. The comment formatting required is easy to follow and very readable, in fact your comments are probably already in the right format (you are writing comments, right?). The output is visually appealing documentation in the form of HTML as well as a fully indexed and browsable Xcode documentation set. Since Xcode 5, there is no official support for 3rd party docsets but tools like Docs for Xcode help to fix that.

Docs for Xcode

With Xcode 5 Apple unfortunately chose to remove support for 3rd party docsets. The documentation viewer will still display any that you have installed but will no longer update them and you can't add new docsets. Docs for Xcode fixes this by letting you install docsets, subscribe to feeds and keep the documentation always up to date. An absolute essential for everyone using Xcode 5.

Once translated you can download your updated files, or use the iOS framework that provides over-the-air localisation so you can update your translations without having to submit your app for review. Localise has built in Google and Yandex machine translations, or you can buy translations for a price per word fee.

Qordoba

A localization SDK and platform for iOS and Android. The Qordoba SDKs work with the asset and localization files in your app to parse and ingest them into the Qordoba platform, a visual web-based solution for editing and managing mobile app UI and the metadata for your app. New languages or updated content can be delivered to your users via Qordoba's SDK so you can add languages on the fly or remove and edit content in existing languages without needing to resubmit your application to the App Store.

POEditor

An online translation and localization management tool. POEditor offers a simple interface for translators, devs and project managers to collaboratively localize apps, websites, games and more. You can customise and automate the localization workflow with the POEditor API and shorten the file management process with the GitHub and Bitbucket integration. POEditor allows you to make your project public, if you want to crowdsource translations, and is free for Open Source projects.

Laurine

A localisation code generator written in Swift. Laurine is a Swift script that scans your localisation file and generates actual structured code in Objective-C or Swift, making the usage of localised strings much easier. It allows you to remove magical strings from your code so the compiler can actually tell you when you forget to make changes if your localisation file changes. It also introduces type checking for strings that contain runtime format specifiers such as "%@" or "%d". The generated structures can also be nested so your localisations can be descriptive and easy to traverse.

Local

A OS X app that provides fast, automatic localization for iOS developers. Local provides an alternative to paying for expensive translators by using Microsoft Translator to automate the process. Simply import your Localizable.strings file, and select the target language, and Local will translate the entire file at once. Local also allows you to create your first Localizable.strings file easily. After you enter all your keys and values into the app, you can copy the base localization into Xcode, which is useful if you want to translate the app by hand, or even have your own translator do so.
