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. -

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. -

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. -

Files
A nicer way to handle files & folders in Swift
Files is a lightweight Swift library that provides a more expressive and user-friendly interface for working with files and directories compared to the native FileManager API. It abstracts common file system operations into an object-oriented model, enabling developers to interact with files and folders using intuitive constructs such as Folder and File types. The library simplifies tasks like reading, writing, moving, renaming, and deleting files while maintaining robust error handling through Swift’s try-catch mechanisms. It also supports recursive traversal of directory structures, making it easy to iterate through file trees for scripting or automation purposes. Designed primarily for Swift scripting and tooling, Files can also be embedded into applications that require file system access. Its implementation is compact and efficient, often contained within a single file, which makes it easy to integrate into projects without adding unnecessary complexity. -
