    Swift Playgrounds

    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.

    Aspects

    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.

    JLRoutes

    JLRoutes

    URL routing library for iOS with a simple block-based API

    JLRoutes is a URL routing library with a simple block-based API. It is designed to make it very easy to handle complex URL schemes in your application with minimal code. JLRoutes is available for installation using CocoaPods or Carthage. JLRoutes 2.x require iOS 8.0+ or macOS 10.10+. If you need to support iOS 7 or macOS 10.9, please use version 1.6.4. The handler block is expected to return a boolean for if it has handled the route or not. If the block returns NO, JLRoutes will behave as if that route is not a match and it will continue looking for a match. A route is considered to be a match if the pattern string matches and the block returns YES. It is also important to note that if you pass nil for the handler block, an internal handler block will be created that simply returns YES. JLRoutes supports setting up routes within a specific URL scheme.

    React Native Voice

    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).

    SocketRocket

    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 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.

    CargoBay

    CargoBay

    The Essential StoreKit Companion

    CargoBay is an Objective-C companion library that simplifies StoreKit-based in-app purchases on Apple platforms. It provides one-step receipt and transaction verification following Apple’s recommended server validation flow. Product information can be requested with block-based callbacks from local identifiers or identifiers supplied by a remote service. Payment queue observer methods are exposed as blocks, reducing the need for repetitive delegate code. The library automatically checks transaction uniqueness to help prevent the same purchase from being processed twice. A shared manager coordinates product lookup, payment events, and receipt verification across the application. CargoBay is MIT-licensed, archived, and no longer maintained, so it mainly serves as a legacy reference for StoreKit integrations.

    CocoaAsyncSocket

    CocoaAsyncSocket

    Asynchronous socket networking library for Mac and iOS

    CocoaAsyncSocket provides easy-to-use and powerful asynchronous socket libraries for macOS, iOS, and tvOS. The classes are described below. The project is currently configured to build for iOS, tvOS and Mac. Simply add the package dependency to your Package.swift and depend on "CocoaAsyncSocket" in the necessary targets. You can also include it into your project by adding the source files directly, but you should probably be using a dependency manager to keep up to date. GCDAsyncSocket is a TCP/IP socket networking library built atop Grand Central Dispatch. Automatically accept incoming connections over both IPv4 and IPv6 with a single instance of this class. No more worrying about multiple sockets. Secure your socket with ease using just a single method call. Available for both client and server sockets. It runs entirely within its own GCD dispatch_queue, and is completely thread-safe. Further, the delegate methods are all invoked asynchronously onto a dispatch_queue of your choosing.
