Open Source Swift Libraries

BulletinBoard is an iOS library that generates and manages contextual cards displayed at the bottom of the screen. It is especially well suited for quick user interactions such as onboarding screens or configuration. It has an interface similar to the cards displayed by iOS for AirPods, Apple TV/HomePod configuration and NFC tag scanning. It supports both the iPhone, iPhone X and the iPad. It has built-in support for accessibility features such as VoiceOver and Switch Control.

A declarative library for building component-based user interfaces in UITableView and UICollectionView. Provides a declarative design with the power of diffing algorithm for building list UIs. Declare the component once, it can be reused regardless kind of the list element. Solves the various problems by architecture and algorithm without destructing UIKit. Carbon is a library for building component-based user interfaces in UITableView and UICollectionView inspired by SwiftUI and React. This make it painless to build and maintain the complex UIs. Since components made with Carbon can be works directly on SwiftUI, the cost of future migration can be greatly reduced. Uses DifferenceKit which is highly optimized based on Paul Heckel’s paper for diffing. Declarative design and diffing algorithm make your code more predictable, debugging easier and providing beautiful animations to users.

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.

Dynamic is an Objective-C library for dynamically interacting with private and public iOS APIs. It allows developers to access properties, methods, and classes that are not normally exposed, useful for runtime exploration and advanced debugging.

MaLiang is a painting framework based on Metal. It supports drawing and handwriting with customized textures. The name of "MaLiang" comes from a boy who had a magical brush in a Chinese ancient fairy story. A Canvas is the basic component of MaLiang. You will paint all things on it. Canvas extends from MetalView, which extends from MTKView. MetalView handles all the logic with MetalKit and hides them from you. MaLiang supports the automatic adjustment of stroke size with painting force. 3D Touch is supported by default, and simulated force will be setup on devices that do not support this. forceSensitive is the property that force affects the stroke size. It should be set between 0 to 1. the smaller the value is, the less sensitive will be. if sets to 0, then force will not affect the stroke size.

A library to present popovers. Present any view above your app's main content. Attach to source views or use picture-in-picture positioning. Display multiple popovers at the same time with smooth transitions. Supports SwiftUI, UIKit, and multitasking windows on iPadOS. Highly customizable API that's super simple — just add .popover. Drop-in replacement for iOS 14's Menu that works on iOS 13. SwiftUI-based core for a lightweight structure. 0 dependencies. It's 2023 — about time that popovers got interesting!

Reel Search is a Swift UI controller that allows you to choose options from a list. We specialize in the designing and coding of custom UI for Mobile Apps and Websites. Once the designers have created a gorgeous UI, you will need a team that will be able to turn this design into a working mobile application or website which will look and work exactly the way you have approved it at the design stage. Ramotion has been creating interfaces for many years and now we are ready to turn them into working mobile, web, and VR apps. Recently, our mobile application developers have released a series of Swift controls, which quickly gained popularity among mobile developers on Github and allowed Ramotion to become the # 1 contributor to Swift projects on the platform.

Type-safe time calculations in Swift. Time is not just a bunch of Double conversion functions. The main advantage of it is that all time units are strongly-typed. Starting with Xcode 11, Time is officially available only via Swift Package Manager. Of course, you always have an option of just copying-and-pasting the code - Time is just two files, so feel free.

TweenKit is a powerful animation library that allows you to animate (or 'tween') anything. TweenKit's animations are also scrubbable, perfect for building awesome onboarding experiences! By adding conformance to the Tweenable protocol, anything can be animated. You decide what it means to 'tween' your object, making this a flexible approach.
