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. -

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. -

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. -

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. -

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. -

XCoordinator
Powerful navigation library for iOS based on the coordinator pattern
Powerful navigation library for iOS based on the coordinator pattern. Create an enum with all of the navigation paths for a particular flow, i.e. a group of closely connected scenes. (It is up to you when to create a Route/Coordinator. As our rule of thumb, create a new Route/Coordinator whenever a new root view controller, e.g. a new navigation controller or a tab bar controller, is needed.). Whereas the Route describes which routes can be triggered in a flow, the Coordinator is responsible for the preparation of transitions based on routes being triggered. We could, therefore, prepare multiple coordinators for the same route, which differ in which transitions are executed for each route. -

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. -

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. -
22
Dollar
A functional tool-belt for Swift Language
Dollar is a Swift library that provides useful functional programming helper methods without extending any built in objects. It is similar to Lo-Dash or Underscore.js in Javascript.
