XcodeProj
Read, update and write your Xcode projects
XcodeProj is a library written in Swift for parsing and working with Xcode projects. It's heavily inspired by CocoaPods XcodeProj and xcode. Using swift-sh you can automate project-tasks using scripts, for example, we can make a script that keeps a project’s version key in sync with the current git tag that represents the project’s version. Future adaption could easily include determining the version and bumping it automatically. If so, we recommend using a library that provides a Version object. Want to start using XcodeProj? Start by digging into our documentation which will help you get familiar with the API and get to know more about the Xcode projects structure. -

Inject
Hot Reloading for Swift applications
Hot reloading workflow helper that enables you to save hours of time each week, regardless if you are using UIKit, AppKit or SwiftUI. Hot reloading is a technique allowing you to get rid of compiling your whole application and avoiding deploy/restart cycles as much as possible, all while allowing you to edit your running application code and see changes reflected as close as possible to real-time. This makes you significantly more productive by reducing the time you spend waiting for apps to rebuild, restart, re-navigate to the previous location where you were in the app itself, re-produce the data you need. You don’t need to add conditional compilation or remove Inject code from your applications for production, it's already designed to behave as no-op inlined code that will get stripped by LLVM in non-debug builds. -

Cache
Nothing but Cache
Cache doesn't claim to be unique in this area, but it's not another monster library that gives you a god's power. It does nothing but caching, but it does it well. It offers a good public API with out-of-box implementations and great customization possibilities. Cache utilizes Codable in Swift 4 to perform serialization. The cache is built based on a Chain-of-responsibility pattern, in which there are many processing objects, each knows how to do 1 task and delegates to the next one, so can you compose Storage the way you like. All Storage now are generic by default, so you can get a type of safety experience. Once you create a Storage, it has a type constraint that you don't need to specify a type for each operation afterward. -

HandyJSON
A handy swift json-object serialization/deserialization library
HandyJSON is a framework written in Swift which makes converting model objects( pure classes/structs ) to and from JSON easy on iOS. Compared with others, the most significant feature of HandyJSON is that it does not require the objects inherit from NSObject(not using KVC but reflection), nor implements a 'mapping' function(writing value to memory directly to achieve property assignment). HandyJSON is totally dependent on the memory layout rules inferred from Swift runtime code. We are watching it and will follow every bit if it changes. To support deserialization from JSON, a class/struct needs to conform to 'HandyJSON' protocol. It's truly protocol, not some class inherited from NSObject. For struct, since the compiler provides a default empty initializer, we use it for free. HandyJSON supports deserialization from the designated path of JSON. -

Swift Macros
A curated list of awesome Swift Macros
Swift Macros is a curated collection of Swift macro resources, tools, examples, and learning material. It is intended for developers who want to understand, build, test, and distribute Swift macros in modern Swift projects. The repository gathers community-created macros alongside frameworks, articles, Apple resources, tutorials, and related tooling. Its structure makes it easier to discover practical macro use cases without searching across scattered blog posts and packages. It is especially valuable for developers moving from code-generation tools toward Swift’s built-in macro system. Swift-Macros is not a single library, but a reference hub for learning the Swift macro ecosystem and finding useful implementation patterns. -

Tokamak
Framework for building browser apps with WebAssembly
Tokamak is an open source framework that aims to replicate a large portion of Apple’s SwiftUI API in order to enable developers to build user interfaces that can run in the browser through WebAssembly as well as on native platforms. It provides a declarative programming model similar to SwiftUI, allowing developers to define views, state, and layout logic using familiar patterns while targeting environments beyond Apple’s ecosystem. The project includes a DOM renderer capable of handling a subset of SwiftUI views and modifiers, alongside additional constructs such as custom HTML rendering for greater flexibility when interacting with web technologies. Tokamak also introduces features like dynamic HTML elements with event listeners and direct DOM manipulation capabilities, which bridge the gap between Swift abstractions and browser-level control. Its architecture draws inspiration from modern UI frameworks. -

AlertToast-SwiftUI
Create Apple-like alerts & toasts using SwiftUI
AlertToast is a SwiftUI-based library that enables developers to display lightweight, non-intrusive notifications and alerts that resemble native Apple system interactions. Unlike traditional alerts that require user confirmation, this library allows for transient messages that automatically dismiss, improving user experience for status updates such as success messages, loading indicators, or errors. It provides multiple display modes including centered alerts, top drop-down HUDs, and bottom banners, giving developers flexibility in how feedback is presented. The library includes several predefined alert types such as complete, error, loading, and image-based notifications, all designed to match Apple’s visual language. It is fully customizable, allowing developers to adjust fonts, colors, and content while maintaining consistency with the system aesthetic. -

DeckTransition
A library to recreate the iOS Apple Music now playing transition
DeckTransition is an attempt to recreate the card-like transition found in the iOS 10 Apple Music and iMessage apps. The transition can be called from code or using a storyboard. To use via storyboards, just setup a custom segue (kind set to custom), and set the class to DeckSegue. Set modalPresentationCapturesStatusBarAppearance to true in your modal view controller, and override the preferredStatusBarStyle variable to return .lightContent. By default, DeckTransition has a swipe-to-dismiss gesture which is automatically enabled when your modalʼs main UIScrollView is scrolled to the top. DeckTransition has an internal heuristic to determine which UIScrollView should be tracked for the swipe-to-dismiss gesture. In general, this should be sufficient for and cover most use cases. -

DeepDiff
Amazingly incredible extraordinary lightning fast diffing in Swift
DeepDiff is a Swift library for efficiently calculating differences between collections and models. It is designed for iOS, macOS, and Swift developers who need fast diffing when updating lists, tables, collection views, or other ordered data displays. The library relies on models conforming to a diff-aware protocol so items can be uniquely identified and compared. This makes it useful for deciding which elements were inserted, deleted, moved, or replaced between two versions of a dataset. DeepDiff helps reduce unnecessary UI reloads by making updates more targeted and animation-friendly. The repository is archived, so it is best treated as a stable reference or legacy dependency rather than an actively evolving Swift package. -

Design Patterns in Swift
Design Patterns implemented in Swift
Design-Patterns-In-Swift is a repository that translates classic software engineering design patterns (from sources like the Gang of Four) into Swift code examples, so you can see how those patterns look in a modern, strongly typed, object-/protocol-oriented language. It covers creational, structural, and behavioral patterns: singletons, factories, decorators, observers, strategy, command, mediator, and more. For each pattern, you’ll typically see one or more Swift implementations, commentary on where it makes sense in a Swift architecture, and caveats about when you might prefer pure protocol composition or using functional patterns instead. The examples aim to be readable and idiomatic—not overly abstract or contrived—so developers can adopt or adapt them directly. -

Differ
Swift library to generate differences and patches between collections
Differ generates the differences between Collection instances. There’s a lot more to calculating diffs than performing table view animations easily. Wherever you have code that propagates added/removed/moved callbacks from your model to your user interface, you should consider using a library that can calculate differences. Animating small batches of changes is usually going to be faster and provide a more responsive experience than reloading all of your data. Calculating and acting on differences should also aid you in making a clear separation between data and user interface, and hopefully provide a more declarative approach: your model performs state transition, then your UI code performs appropriate actions based on the calculated differences to that state. -

Dollar
A functional tool-belt for Swift Language
Dollar is a Swift library that provides useful functional programming helper methods without extending any built in objects. It is similar to Lo-Dash or Underscore.js in Javascript. Cent is a library that extends certain Swift object types using the extension feature and gives its two cents to Swift language. It is now moved into a separate repo to support Swift Package Manager. -
