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. -

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. -

Posturr
A macOS app that blurs your screen when you slouch
Posturr is a macOS application that uses computer vision and machine learning — specifically Apple’s Vision framework — to monitor a user’s posture in real time and encourage healthier habits by visually responding when poor posture is detected. Running locally on the Mac, the app accesses the built-in camera to detect when you slouch or sit incorrectly, and when it recognizes sustained slouching, it applies a progressive visual blur to the screen as a subtle but effective cue to straighten up. This approach turns posture correction into an interactive feedback loop that doesn’t require wearables or external sensors, prioritizing privacy because all image processing happens on the device with no cloud transmission. It’s helpful for people who spend long hours working at a desk and want a gentle reminder to maintain ergonomic alignment without intrusive notifications. -

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. -

CardParts
A reactive, card-based UI framework built on UIKit for iOS developers
CardParts is the second-generation Card UI framework for the iOS Mint application. This version includes many updates to the original card part framework, including improved MVVM, data binding (via RxSwift), use of stack views and self-sizing collection views instead of sizing cells, 100% swift and much more. The result is a much simpler, easier-to-use, more powerful, and easier-to-maintain framework. This framework is currently used by the iOS Mint application and the iOS Turbo application. There are two major parts to the card parts framework. The first is the CardsViewController which will display the cards. It is responsible for displaying cards in the proper order and managing the lifetime of the cards. The second major component is the cards themselves which are typically instances of CardPartsViewController. Each instance of CardPartsViewController displays the content of a single card, using one or more card parts (more details later). -

Carthage
A simple, decentralized dependency manager for Cocoa
Carthage is intended to be the simplest way to add frameworks to your Cocoa application. Carthage builds your dependencies and provides you with binary frameworks, but you retain full control over your project structure and setup. Carthage does not automatically modify your project files or your build settings. Get Carthage by running brew install carthage or choose another installation method. Create a Cartfile in the same directory where your .xcodeproj or .xcworkspace is. List the desired dependencies in the Cartfile. Once you have Carthage installed, you can begin adding frameworks to your project. Note that Carthage only supports dynamic frameworks, which are only available on iOS 8 or later (or any version of OS X). We encourage using XCFrameworks as of version 0.37.0 (January 2021), and require XCFrameworks when building on an Apple Silicon Mac. Switching from discrete framework bundles to XCFrameworks requires a few changes to your project. -

Chatto
A lightweight framework to build chat applications, made in Swift
Chatto is a Swift lightweight framework to build chat applications. It's been designed to be extensible and performant. Along with Chatto there is ChattoAdditions, a companion framework which includes cells for messages and an extensible input component. You can find more details about how it was implemented in our blog. Chatto is a Swift framework to ease the development of chat applications. At the UI level, it takes care of managing the UICollectionView where the messages are displayed and provides a placeholder for an input component. Provides support for interactive dismissal of the keyboard and adjusts the insets automatically when it appears. Calculates this layout in a background queue (partially if your sizing routines can be only executed in the main thread). Triggers notifications to the data source to retrieve more messages (pagination). Encourages clean code by decoupling your message's presentation into different presenters. -
19
Cleanse
Lightweight Swift Dependency Injection Framework
Cleanse is a dependency injection framework for Swift. It is designed from the ground-up with developer experience in mind. It takes inspiration from both Dagger and Guice. Cleanse is responsible for building a graph (or more specifically a directed acyclic graph) that represents all of your dependencies. This graph starts with a root object which is connected to its immediate dependencies, and those dependencies hold edges to its dependencies and so on until we have a complete picture of your application's object graph. The entry point into managing your dependencies with Cleanse starts by defining a "Root" object that is returned to you upon construction. In a Cocoa Touch application, our root object could be the rootViewController object we set on the application's UIWindow. (More logically the root object is the App Delegate, however, since we don't control the construction of that we would have to use Property Injection. -

CoreRender
UIKit a-là SwiftUI.framework
CoreRender is a SwiftUI-inspired API for UIKit (that is compatible with iOS 10+ and ObjC). CoreRender uses a declarative API to define UI components. You simply describe the layout for your UI based on a set of inputs and the framework takes care of the rest (diff and reconciliation from virtual view hierarchy to the actual one under the hood). CoreRender includes the robust and battle-tested Facebook's Yoga as default layout engine. Any component such as a text or image can be recycled and reused anywhere in the UI. -

DifferenceKit
A fast and flexible O(n) difference algorithm framework
A fast and flexible O(n) difference algorithm framework for Swift collection. The algorithm is optimized based on the Paul Heckel’s algorithm. This is a diffing algorithm developed for Carbon, works stand alone. The algorithm optimized based on the Paul Heckel’s algorithm. See also his paper A technique for isolating differences between files released in 1978. It allows all kind of diffs to be calculated in linear time O(n). RxDataSources and IGListKit are also implemented based on his algorithm. The type of the element that to take diffs must be conform to the Differentiable protocol. -

Go to your storyboard file, choose or create the view controller that should present the epub reader. In the identity, the inspector set StoryboardFolioReaderContrainer as a class. Media Overlays (Sync text rendering with audio playback). TTS - Text to Speech Support, parse epub cover image, RTL Support. Vertical or/and Horizontal scrolling, share Custom Image Quotes NEW, supports multiple instances at same time, like parallel reading. -
23
Foundation
Provides core utilities, internationalization, and OS independence
The Foundation framework defines a base layer of functionality that is required for almost all applications. It provides primitive classes and introduces several paradigms that define functionality not provided by either the Objective-C runtime and language or Swift standard library and language. This project, swift-corelibs-foundation, provides an implementation of the Foundation API for platforms where there is no Objective-C runtime. On macOS, iOS, and other Apple platforms, apps should use the Foundation that comes with the operating system. Our goal is for the API in this project to match the OS-provided Foundation and abstract away the exact underlying platform as much as possible. We believe that the Swift standard library should remain small and laser-focused on providing support for language primitives. -

GPUImage 2
Framework for GPU-accelerated video and image processing
GPUImage 2 is the second generation of the GPUImage framework, an open source project for performing GPU-accelerated image and video processing on Mac, iOS, and now Linux. The original GPUImage framework was written in Objective-C and targeted Mac and iOS, but this latest version is written entirely in Swift and can also target Linux and future platforms that support Swift code. The objective of the framework is to make it as easy as possible to set up and perform realtime video processing or machine vision against image or video sources. By relying on the GPU to run these operations, performance improvements of 100X or more over CPU-bound code can be realized. This is particularly noticeable in mobile or embedded devices. On an iPhone 4S, this framework can easily process 1080p video at over 60 FPS. On a Raspberry Pi 3, it can perform Sobel edge detection on live 720p video at over 20 FPS. -
