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. -

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. -

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. -

OHHTTPStubs
Stub your network requests easily!
OHHTTPStubs is a library designed to stub your network requests very easily. It can help you test your apps with fake network data (stubbed from file) and simulate slow networks, to check your application behavior in bad network conditions, and write unit tests that use fake network data from your fixtures. OHHTTPStubs headers are fully documented using Appledoc-like / Headerdoc-like comments in the header files. Instead of writing the content of the stubs you want to use manually, you can use tools like SWHttpTrafficRecorder to record network requests into files. This way you can later use those files as stub responses. OHHTTPStubs is split into subspecs so that when using Cocoapods, you can get only what you need, no more, no less. OHHTTPStubs supports Swift 2.2 (Xcode 7), Swift 2.3 (Xcode 8), Swift 3.0 (Xcode 8+) and Swift 3.1 (Xcode 8.3+). -

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.
