PanelKit is a UI framework that enables panels on iOS.

A panel can be presented in the following ways:

• Modally
• As a popover
• Floating (drag the panel around)
• Pinned (either left or right)

This framework does all the heavy lifting for dragging panels, pinning them and even moving/resizing them when a keyboard is shown/dismissed.

AppAuth for iOS and macOS is a client SDK for communicating with OAuth 2.0 and OpenID Connect providers. It strives to directly map the requests and responses of those specifications, while following the idiomatic style of the implementation language. In addition to mapping the raw protocol flows, convenience methods are available to assist with common tasks like performing an action with fresh tokens.

Impeller is a Distributed Value Store (DVS) written in Swift. It was inspired by successful Distributed Version Control Systems (DVCSes) like Git and Mercurial, and appropriates the concept and terminology for use with application data, rather than source code files.

With Impeller, you compose a data model from Swift value types (structs), and persist them locally in a store like SQlite. Values can be pushed to services like CloudKit, and pulled down to other devices, to facilitate sync across devices, and with web apps.

iOS let's you modally present any view controller, but if you want the presented view controller to not cover the whole screen or modify anything about its presentation or transition you have to use the Custom View Controller Presentation API's.

This can be cumbersome, specially if you do it multiple times in your app. Presentr simplifies all of this. You just have to configure Presentr depending on how you want you view controller to be presented, and the framework handles everything for you.

Katana is a modern Swift framework for writing iOS and macOS apps, strongly inspired by React and Redux, that gives structure to all the aspects of your app:

• logic: the app state is entirely described by a single serializable data structure, and the only way to change the state is to dispatch an action. An action is an intent to transform the state, and contains all the information to do so. Because all the changes are centralized and are happening in a strict order, there are no subtle race conditions to watch out for.
• UI: the UI is defined in terms of a tree of components declaratively described by props (the configuration data, i.e. a background color for a button) and state (the internal state data, i.e. the highlighted state for a button). This approach lets you think about components as isolated, reusable pieces of UI, since the way a component is rendered only depends on the current props and state of the component itself.
• logic <-> UI: the UI components are connected to the app state and will be automatically updated on every state change. You control how they change, selecting the portion of app state that will feed the component props. To render this process as fast as possible, only the relevant portion of the UI is updated.
• layout: Katana defines a concise language (inspired by Plastic) to describe fully responsive layouts that will gracefully scale at every aspect ratio or size, including font sizes and images.

StyleKit is a microframework that enables you to style your applications using a simple JSON file. Behind the scenes, StyleKit uses UIAppearance and some selector magic to apply the styles. You can also customize the parser for greater flexibility.

ResponseDetective is a non-intrusive framework for intercepting any outgoing requests and incoming responses between your app and your server for debugging purposes.

ExpandingCollection is a card peek/pop controller.

Hero is a library for building iOS view controller transitions. It provides a layer on top of the UIKit's cumbersome transition APIs. Making custom transitions an easy task for developers.

Dance is a powerful and straightforward animation framework built upon the new UIViewPropertyAnimator class introduced in iOS 10. With Dance, creating an animation for a view is as easy as calling view.dance.animate { ... }, which can then be started, paused, reversed, scrubbed through, and finished anywhere that the view can be referenced. Dance is especially forgiving, and provides the power that UIViewPropertyAnimator brings to iOS while maintaining ease of use.

Features:

• Shortest possible syntax for creating layout constraints.
• Constraints are active by default.
• 100% compatible with Auto Layout.
• Optionally store your constraints.
• Set constraint priorities upon creation.
• Stack views together with one line of code.

Simple code editor for Swift specially designed for ease of use without all the bloat of Xcode, just ten megs instead of four gigs. Ideal for coding server apps in Swift, html, css and js. Of course there is no Interface Builder and all the fancy toys, just an editor for quick hacks.

Smart and beautiful POSIX compliant CLI framework for Swift.
It helps you create modern and familiar CLI apps in the vein of widely used projects such as: Docker, Kubernetes, OpenShift, Hugo and more!.

Guaka is both a swift library and a command line application that help generate Guaka projects. Inspired by the amazing Cobra package from the Golang's ecosystem.

Macaw is a powerful and easy-to-use vector graphics library written in Swift.

NMessenger is a fast, lightweight messenger component built on AsyncDisplaykit and written in Swift. Developers can inherently achieve 60FPS scrolling and smooth transitions with rich content components.

Palm trees, coral reefs and breaking waves. Welcome to the surf club Malibu, a networking library built on promises. It's more than just a wrapper around URLSession, but a powerful framework that helps to chain your requests, validations and request processing.

Using When under the hood, Malibu adds a lot of sugar helpers and moves your code up to the next level:

• No more "callback hell".
• Your requests are described in one place.
• Response processing could be easily broken down into multiple logical tasks.
• Data and errors are handled separately.
• Your networking code is much cleaner, readable and follows DRY principle.

Equip yourself with the necessary gears of Malibu, become a big wave surfer and let the days of shark infested asynchronous networking be a thing of the past. Enjoy the ride!

CalendarKit is a fully customizable calendar library written in Swift. It was designed to look similar to iOS Calendar app out-of-the-box, but allow complete customization when needed. To make modifications easy, CalendarKit is composed of multiple small modules. They can be used together, or on their own.

• Fast: LayoutKit is as fast as manual layout code and is significantly faster than Auto Layout.
• Asynchronous: Layouts can be computed in a background thread so user interactions are not interrupted.
• Declarative: Layouts are declared with immutable data structures. This makes layout code easier to develop, document, code review, test, debug, profile, and maintain.
• Cacheable: Layout results are immutable data structures so they can be precomputed in the background and cached to increase user perceived performance.
