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. -

Hero iOS
Elegant transition library for iOS & tvOS
Hero is a library for building iOS view controller transitions. It provides a declarative layer on top of the UIKit’s cumbersome transition APIs—making custom transitions an easy task for developers. Hero is similar to Keynote’s Magic Move. It checks the heroID property on all source and destination views. Every matched view pair is then automatically transitioned from its old state to its new state. Hero can also construct animations for unmatched views. It is easy to define these animations via the heroModifiers property. Hero will run these animations alongside the Magic Move animations. All of these animations can be interactively controlled by user gestures. By default, Hero provides dynamic duration based on the Material Design Motion Guide. Duration is automatically determined by changes to distance and size—saving you the hassle, while providing consistent and delightful animations. -

KMM ViewModel
Library to share Kotlin ViewModels with SwiftUI
A library that allows you to share ViewModels between Android and iOS. The latest version of the library uses Kotlin version 1.9.22. Compatibility versions for older and/or preview Kotlin versions are also available. When subclassing your Kotlin ViewModel in Swift you might experience some issues in the way those ViewModels are cleared. Since currentTimeFlow is a StateFlow we don't ever expect it to fail, which is why we are using the assertNoFailure. However, in this case you'll notice that the publisher will fail with a JobCancellationException. The problem here is that before the TimeTravelViewModel is deinited it will already be cleared. Meaning the viewModelScope is cancelled and onCleared is called. This results in the Combine publisher outliving the underlying StateFlow collection. -

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. -

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. -

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. -

LayoutKit
LayoutKit is a fast view layout library for iOS, macOS, and tvOS
LayoutKit is a fast view layout library for iOS, macOS, and tvOS. LinkedIn created LayoutKit because we have found that Auto Layout is not performant enough for complicated view hierarchies in scrollable views. LayoutKit is as fast as manual layout code and is significantly faster than Auto Layout.Layouts can be computed in a background thread so user interactions are not interrupted. Layouts are declared with immutable data structures. This makes layout code easier to develop, document, code review, test, debug, profile, and maintain. Layout results are immutable data structures so they can be precomputed in the background and cached to increase user perceived performance. -

Sheeeeeeeeet
Sheeeeeeeeet is a Swift library for creating menus
Sheeeeeeeeet is a UIKit library that lets you create menus that can be presented as custom action sheets, context menus, alert controllers, or in any way you like. Sheeeeeeeeet comes with many item types (standard items, buttons, titles, toggles, etc.) and can be extended with your own custom item types. Since I have personally moved over to SwiftUI, this repository is no longer under active development. I will however gladly merge any PRs that add value to it or fixes problems with new iOS versions. -

23
Starscream
Websockets in swift for iOS and OSX
Starscream is a conforming WebSocket (RFC 6455) library in Swift. Once imported, you can open a connection to your WebSocket server. Note that socket is probably best as a property, so it doesn't get deallocated right after being setup. After you are connected, there is either a delegate or closure you can use for process WebSocket events. The writeData method gives you a simple way to send Data (binary) data to the server. The writeString method is the same as writeData, but sends text/string. The writePing method is the same as write, but sends a ping control frame. Starscream will automatically respond to incoming ping control frames so you do not need to manually send pongs. You can override the default websocket headers, add your own custom ones and set a timeout. Update docs on how to load certificates and public keys into an app bundle, use the builtin pinner and TrustKit. -
24
Time
Type-safe time calculations in Swift
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. -
25
Vision Camera
The Camera library that sees the vision
VisionCamera was designed from the ground up to provide all features a camera app should have. You have full control over what device is used, and can even configure options such as frame rate, colorspace, and more. While having a lot of features, VisionCamera makes sure you don't get overwhelmed from the beginning. It provides hooks and functions to help you get started faster, and if you need full control, you can easily do that. Every functionality has been thoroughly documented and even errors are fully typed. Use TypeScript to get compile-time feedback on what has gone wrong.
