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. -

Swift Playgrounds
Better playgrounds that work both for Objective-C and Swift
Playgrounds is an enhanced Swift playground-style project that supports both Swift and Objective-C experimentation. It was created to improve the quick code-testing experience by avoiding the traditional edit, compile, run, and debug cycle. The project lets developers try small ideas, inspect results quickly, and explore language behavior in a more interactive workflow. Unlike standard Swift-only playground assumptions, it highlights support for Objective-C as part of the same experimentation model. It is useful for iOS and macOS developers who want a lightweight scratchpad for APIs, language features, and small implementation tests. Its main value is making fast native-code exploration more convenient for mixed Swift and Objective-C environments. -

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. -

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. -

FCUUID
iOS UUID / Universally Unique Identifiers library
iOS UUID library as alternative to the old good UDID and identifierForVendor. This library provides the simplest API to obtain universally unique identifiers with different levels of persistence.

PocketSVG
Easily convert your SVG files into CGPaths, CAShapeLayers, etc.
A simple toolkit for displaying and manipulating SVGs on iOS and macOS in a performant manner. The goal of this project is not to be a fully compliant SVG parser/renderer. But rather to use SVG as a format for serializing CG/UIPaths, meaning it only supports SVG features that can be represented by CG/UIPaths. Thoroughly documented. -

React Native Camera Kit
A high performance, easy to use, rock solid camera library
A high-performance, easy-to-use, rock-solid, camera library for React Native apps. A temporary file is created. You must move this file to a permanent location (e.g. the app's 'Documents' folder) if you need it beyond the current session of the app as it may be deleted when the user leaves the app. You can move files by using a file systems library such as react-native-fs or expo-filesystem. (On Android we currently have an unsupported output path prop but it's subject to change at any time). -

React Native Voice
React Native Voice Recognition library for iOS and Android
A speech-to-text library for React Native. Manually or automatically link the NativeModule. Drag the Voice.xcodeproj from the @react-native-voice/voice/ios folder to the Libraries group on Xcode in your project. Click on your main project file (the one that represents the .xcodeproj) select Build Phases and drag the static library, lib.Voice.a, from the Libraries/Voice.xcodeproj/Products folder to Link Binary With Libraries. The plugin provides props for extra customization. Every time you change the props or plugins, you'll need to rebuild (and prebuild) the native app. If no extra properties are added, defaults will be used. While the included VoiceTest app works without explicit permissions checks and requests, it may be necessary to add a permission request for RECORD_AUDIO for some configurations. Since Android M (6.0), user need to grant permission at runtime (and not during app installation). -
