Aspects
Library for aspect oriented programming in Objective-C and Swift
A delightful, simple library for aspect oriented programming. Think of Aspects as method swizzling on steroids. It allows you to add code to existing methods per class or per instance, whilst thinking of the insertion point e.g. before/instead/after. Aspects automatically deals with calling super and is easier to use than regular method swizzling. Aspects hooks deep into the class hierarchy and creates dynamic subclasses, much like KVO. There's known issues with this approach, and to this date (February 2019) I STRICTLY DO NOT RECOMMEND TO USE Aspects IN PRODUCTION CODE. We use it for partial test mocks in, PSPDFKit, an iOS PDF framework that ships with apps like Dropbox or Evernote, it's also very useful for quickly hacking something up. Aspects uses _objc_msgForward which causes issues with other code that uses message forwarding. -

Pop
iOS and OS X animation library for physics-based interactions
Pop is an extensible animation engine for iOS, tvOS, and OS X. In addition to basic static animations, it supports spring and decay dynamic animations, making it useful for building realistic, physics-based interactions. The API allows quick integration with existing Objective-C or Swift codebases and enables the animation of any property on any object. It's a mature and well-tested framework that drives all the animations and transitions in Paper. By adding the project to your project and adding pop.embedded framework to the Embedded Binaries section on the General tab of your app's target, you can set up pop in seconds! The Pop interface is implemented as a category addition on NSObject. Any NSObject or subclass can be animated. There are four concrete animation types: spring, decay, basic and custom. -

SocketRocket
A conforming Objective-C WebSocket client library
A conforming WebSocket (RFC 6455) client library for iOS, macOS and tvOS. SocketRocket currently conforms to all core ~300 of Autobahn's fuzzing tests (aside from two UTF-8 ones where it is merely non-strict tests 6.4.2 and 6.4.4). SocketRocket is asynchronous and non-blocking. Most of the work is done on a background thread. You can include SocketRocket as a subproject inside of your application if you'd prefer, although we do not recommend this, as it will increase your indexing time significantly. To do so, just drag and drop the SocketRocket.xcodeproj file into your workspace. Included are setup scripts for the python testing environment. It comes packaged with vitualenv so all the dependencies are installed in userland. SocketRocket includes a demo app, TestChat. It will "chat" with a listening websocket on port 9900. The sever takes a message and broadcasts it to all other connected clients. -

AppDevKit
AppDevKit is an iOS development library
AppDevKit is an iOS development library that provides developers with useful features to fulfill their everyday iOS app development needs. AppDevKit is an iOS development library that provides developers with useful features to fulfill their everyday iOS app development needs. Yahoo’s Taiwan based iOS app development team has been using this development kit for the past three years, and we plan future apps to use AppDevKit as well. Our use of this code in many apps helped improve its stability and utility. We find these libraries help address some incompatibility issues found in different iOS versions, and overall make app development easier and our apps operate more consistently. AppDevKit has five major parts that include command, user interfaces, animations, image view, and list view support libraries. AppDevKit could be installed by CocoaPods. Please feel welcome to use AppDevKit in your iOS projects as it is licensed under the permissive open source BSD license. -

FastImageCache
iOS library for quickly displaying images while scrolling
Fast Image Cache is an efficient, persistent, and, above all, fast way to store and retrieve images in your iOS application. Part of any good iOS application's user experience is fast, smooth scrolling, and Fast Image Cache helps make this easier. A significant burden on performance for graphics-rich applications like Path is image loading. The traditional method of loading individual images from disk is just too slow, especially while scrolling. Fast Image Cache was created specifically to solve this problem. In order to understand how Fast Image Cache works, it's helpful to understand a typical scenario encountered by many applications that work with images. iOS applications, especially those in the social networking space, often have many images to display at once, such as user photos. The intuitive, traditional approach is to request image data from an API, process the original images to create the desired sizes and styles, and store these processed images on the device. -
