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. -

Jelly
Library for animated, non-interactive & interactive transitions
Jelly is a library for animated, non-interactive & interactive view controller transitions and presentations with a focus on a simple yet flexible API. With a few lines of source code, interactive UIViewController transitions and custom resizable UIViewController presentations can be created, without the use of the cumbersome UIKit Transitioning API. Interactive transitions can be activated for the slide and the cover transitions. If the transitions are to be interactive, only an InteractionConfiguration object has to be passed to the presentation. Here 3 parameters play an important role. First, the completion threshold, determines the percentage of the animation that is automatically completed as soon as the user finishes the interaction. The second parameter is the actual type of interaction. Jelly offers the .edge and the .canvas type. In a .edge transition, the user must execute the gesture from the edge of the screen. -

MaLiang
iOS painting and drawing library based on Metal
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. -

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. -

Amazon Chime SDK for iOS
An iOS client library for integrating multi-party communications
The Amazon Chime SDK for iOS makes it easy to add collaborative audio calling, video calling, and screen share viewing features to iOS applications by using the same infrastructure services that power meetings on the Amazon Chime service. This Amazon Chime SDK for iOS works by connecting to meeting session resources that you have created in your AWS account. The SDK has everything you need to build custom calling and collaboration experiences in your iOS application, including methods to: configure meeting sessions, list, and select audio devices, switch video devices, start and stop screen share viewing, and receive callbacks when media events occur such as volume changes, and manage meeting features such as audio mute and video tile bindings. You can integrate Amazon Chime SDK in your project from either CocoaPods or binaries through Github release. -

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. -

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. -

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.
