Quick
The Swift (and Objective-C) testing framework
Quick is a behavior-driven development framework for Swift and Objective-C. Inspired by RSpec, Specta, and Ginkgo. Quick comes together with Nimble, a matcher framework for your tests. Certain versions of Quick and Nimble only support certain versions of Swift. Depending on which version of Swift your project uses, you should use specific versions of Quick and Nimble. When code doesn't work the way it's supposed to, unit tests should make it clear exactly what's wrong. Nimble makes your test assertions, and their failure messages, easier to read. Nimble provides many different kind of assertions, each with great failure messages. And unlike XCTAssert, you don't have to type your own failure message every time. All documentation can be found in the Documentation folder, including detailed installation instructions for CocoaPods, Carthage, Git submodules, and more. -

Swift Cross UI
A cross-platform declarative UI framework, inspired by SwiftUI
SwiftCrossUI implements a simple API similar but not identical to SwiftUI, allowing you to use the basic concepts of SwiftUI to create a cross-platform desktop app. SwiftCrossUI is designed to be flexible and can work with different backends, but has a focus on using GTK+ through SwiftGTK. Create cross-platform desktop apps for macOS, Linux and Windows. Work has been started to support multiple different backends. Switching backends only requires changing a single line of code! Currently there's the Gtk 4 backend, as well as an experimental AppKit backend (AppKitBackend, macOS-only). All examples use GtkBackend for maximum compatibility, but you can update them manually to try out the various available backends. Work is being done to allow the backend used by the examples to be changed from the command line. -

PhoneNumberKit
A Swift framework for parsing and formatting phone numbers
Swift 5.3 framework for parsing, formatting and validating international phone numbers. Inspired by Google's libphonenumber. Import PhoneNumberKit at the top of the Swift file that will interact with a phone number. All of your interactions with PhoneNumberKit happen through a PhoneNumberKit object. The first step you should take is to allocate one. A PhoneNumberKit instance is relatively expensive to allocate (it parses the metadata and keeps it in memory for the object's lifecycle), you should try and make sure PhoneNumberKit is allocated once and deallocated when no longer needed. To parse a string, use the parse function. The region code is automatically computed but can be overridden if needed. PhoneNumberKit automatically does a hard type validation to ensure that the object created is valid, this can be quite costly performance-wise and can be turned off if needed. -

Spots
Spots is a cross-platform view controller framework
Spots is a cross-platform view controller framework for building component-based UIs. The internal architecture is built using generic view models that can be transformed both to and from JSON. So, moving your UI declaration to a backend is as easy as pie. Data source and delegate setup is handled by Spots, so there is no need for you to do that manually. The public API is jam-packed with convenience methods for performing mutation, it is as easy as working with a regular collection type. At the top level of Spots, you have the SpotsController which is the replacement for your view controller. -

APNGKit
High performance and delightful way to play with APNG format in iOS
The APNGKit project is a high-performance framework for loading, displaying, and animating images in the UIKit / AppKit ecosystem (iOS, macOS, tvOS), specifically targeting the APNG (Animated PNG) image format. Unlike traditional static PNG images, APNG supports frame-by-frame animation with full-color images and transparency — yielding better visual fidelity than GIFs while remaining efficient. APNGKit offers a friendly API (e.g. APNGImage, APNGImageView) that behaves similarly to the standard image/image-view pattern, making it easy for iOS/macOS developers to adopt without learning complex new APIs. It handles loading, decoding, timing, and rendering of animated PNG frames, providing smooth animations, correct color and transparency handling, and performance optimizations. The library supports modern Apple platforms (iOS, macOS, tvOS, visionOS) and works with standard dependency managers (Swift Package Manager, CocoaPods), making integration into existing projects straightforward. -

Katana
Swift Apps in a Swoosh! A modern framework for creating iOS apps
Katana is a modern Swift framework for writing iOS applications' business logic that are testable and easy to reason about. Katana is strongly inspired by Redux. In a few words, the app state is entirely described by a single serializable data structure, and the only way to change the state is to dispatch a StateUpdater. A StateUpdater is an intent to transform the state, and contains all the information to do so. Because all the changes are centralized and are happening in a strict order, there are no subtle race conditions to watch out for. We feel that Katana helped us a lot since we started using it in production. Our applications have been downloaded several millions of times and Katana really helped us scale them quickly and efficiently. Bending Spoons's engineers leverage Katana capabilities to design, implement and test complex applications very quickly without any compromise to the final result. -

Nimble
A Matcher Framework for Swift and Objective-C
Use Nimble to express the expected outcomes of Swift or Objective-C expressions. Inspired by Cedar. Apple's Xcode includes the XCTest framework, which provides assertion macros to test whether code behaves properly. XCTest assertions have a couple of drawbacks. Not enough macros. There's no easy way to assert that a string contains a particular substring, or that a number is less than or equal to another. It's hard to write asynchronous tests. XCTest forces you to write a lot of boilerplate code. Nimble addresses these concerns. Would you like to add more information to the test's failure messages? Use the description optional argument to add your own text. Nimble makes sure you don't compare two types that don't match. Tired of so much typing? With Nimble, you can use overloaded operators like == for equivalence, or > for comparisons. -

SwiftNIO
Network application framework for protocol servers and clients
SwiftNIO is a cross-platform asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Low-level protocol implementations are often a collection of ChannelHandlers that implement a protocol but still require the user to have a good understanding of SwiftNIO. Often, low-level protocol implementations will then be wrapped in high-level libraries with a nicer, more user-friendly API. High-level implementations are usually libraries that come with an API that doesn't expose SwiftNIO's ChannelPipeline and can therefore be used with very little (or no) SwiftNIO-specific knowledge. The implementations listed below do still do all of their I/O in SwiftNIO and integrate really well with the SwiftNIO ecosystem. SwiftNIO aims to support all of the platforms where Swift is supported. Currently, it is developed and tested on macOS and Linux. -

Blueprints
A framework that is meant to make your life easier
Blueprints is a collection of flow layouts that is meant to make your life easier when working with collection view flow layouts. It comes with two built-in layouts that are highly flexible and easy to configure at the call site. They support properties like items per row and items per column; this will calculate the layout attributes needed for fitting the number of views that you want to appear on the screen. The framework also provides a good base for your custom implementations. By extending the core blueprint layout, you get built-in support for animations and layout attribute caching. The bundled default animator supports animations that look very similar to what you get from a vanilla table view. If you want to provide your collection view animator, no problem; you can inject an animator of your choosing when initializing the layout.
