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. -

CYLTabBar Controller
iOS UI module library for adding animation to iOS tabbar items
It is an iOS UI module library for adding animation to iOS tabbar items and icons with Lottie, and adding a bigger center UITabBar Item. One line of code to implement Lottie animation TabBar, support middle with + sign. The TabBar style comes with a red dot corner mark and supports dynamic refresh. One line of code supports Lottie animation TabBar style. This library is independent of your business codes which only needs two array parameters to be passed. PlusButton can be deleted dynamically, and the style can be dynamically updated. Let TabBarItemicon is displayed only, and automatically makes the icon vertically centered, support for custom TabBar height. Support multiple TabBar nesting and specify PlusButton position. Support horizontal and vertical screen. It also supports the creation of customized irregularly shaped plus buttons. -

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. -

DateTools
Dates and times made easy in iOS
DateTools was written to streamline date and time handling in iOS. Classes and concepts from other languages served as an inspiration for DateTools, especially the DateTime structure and Time Period Library for .NET. Through these classes and others, DateTools removes the boilerplate required to access date components, handles more nuanced date comparisons, and serves as the foundation for entirely new concepts like Time Periods and their collections. All the classes required for DateTools are located in the DateTools folder in the root of this repository. DateTools.h contains the headers for all the other files. Import this if you want to link to the entire framework. One of the missions of DateTools was to make Date feel more complete. There are many other languages that allow direct access to information about dates from their date classes, but Date (sadly) does not. -

FBRetainCycleDetector
iOS library to help detecting retain cycles in runtime
Retain cycles are one of the most common ways of creating memory leaks. It's incredibly easy to create a retain cycle, and tends to be hard to spot it. The goal of FBRetainCycleDetector is to help find retain cycles at runtime. The features of this project were influenced by Circle. FBRetainCycleDetector will look for cycles that are no longer than 10 objects. We can make it bigger (although it's going to be slower!). There could also be retain cycles that we would like to omit. It's because not every retain cycle is a leak, and we might want to filter them out. Every filter is a block that having two FBObjectiveCGraphElement objects can say, if their relation is valid. If you want to profile your app, you might want to have an abstraction over how to get candidates for FBRetainCycleDetector. While you can simply track it your own, you can also use FBAllocationTracker. It's a small tool we created that can help you track the objects. -

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. It's possible to retrieve the UUIDs created for all devices of the same user, in this way with a little bit of server-side help it's possible manage guest accounts across multiple devices easily. -

FXForms
Library for easily creating table-based forms on iOS
FXForms is a form-building framework for iOS that turns model definitions into polished data-entry screens with minimal boilerplate. You describe your form fields declaratively—types, titles, options, validation hints—and the library generates a UITableView-based UI using appropriate cells and input controls. It supports common patterns like pickers, switches, segmented controls, text fields, and text views, while letting you supply custom cells when your design demands it. The framework handles value binding between the UI and your model object, so you don’t have to wire up outlets or write repetitive save/validate code. Navigation behaviors such as next-field focus and section grouping are built in, improving usability out of the box. By reducing form glue code, FXForms helps teams ship consistent, maintainable data-entry flows faster, especially in apps with many settings or profile screens. -

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. -
