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. -

JSONKit
Objective-C JSON
JSONKit is a high-performance Objective-C library for parsing and generating JSON on iOS and macOS, created before Apple’s built-in JSON APIs were widely available. It focuses on speed and low memory overhead, using tight C/Objective-C code paths to turn NSData into Foundation containers (arrays, dictionaries) and back again. The API provides flexible options such as mutable or immutable containers, pretty printing, and tolerances for common JSON formatting quirks. Developers can stream or parse in one shot, and they get predictable error reporting when malformed input is encountered. Because the output is standard Foundation objects, it drops into existing code with minimal adaptation. Even as the platform matured, JSONKit remained a reference point for how to write fast, reliable serialization code on Apple platforms. -

JXCategoryView
A powerful and easy to use category view
JXCategoryView is a powerful segmented controller and category selector for iOS that pairs naturally with paged content. It offers multiple built-in cell styles—plain titles, titles with images, badges/dots, and number indicators—so you can match the UX of news, e-commerce, or media apps. A rich indicator system (lines, gradients, masks, background bars, zoom/scale effects) keeps the selection state visually obvious and polished. The library provides a companion list container to manage child view controllers or lists, synchronizing scroll progress with title transitions for buttery navigation. Its delegate/data-source design and property-driven customization make it easy to tune colors, fonts, spacing, and animation timing. With careful handling of reuse and gestures, it stays smooth inside complex hierarchies like nested scroll views and tab bars. -

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+). -

PNChart
A simple and beautiful chart lib used in Piner and CoinsMan for iOS
A simple and beautiful chart lib with animation used in Piner and CoinsMan for iOS. PNChart works on iOS 7.0+ and is compatible with ARC projects. If you need support for iOS 6, use PNChart <= 0.8.1. Note that 0.8.2 supports iOS 8.0+ only, 0.8.3 and newer supports iOS 7.0+. It depends on the following Apple frameworks, which should already be included with most Xcode templates, Foundation.framework, UIKit.framework, CoreGraphics.framework, and QuartzCore.framework. You will need LLVM 3.0 or later in order to build PNChart. CocoaPods is the recommended way to add PNChart to your project. You can choose to show smooth lines. You can set different colors for the same PNLineChartData item. for instance you can use "color" red for values less than 50 and use purple for values greater than 150. Legend has been added to PNChart for Line and Pie Charts. Legend items position can be stacked or in series. -

Play-With-Sort-OC
Repository implemented in Objective-C with sorting algorithms
Play-With-Sort-OC is a learning-oriented repository implemented in Objective-C that demonstrates several classic sorting algorithms with code examples (selection sort, bubble sort, insertion sort, quick sort variants, heap sort, etc). The goal is educational; by showing how each algorithm works with animations or clear visualizations in an iOS/Objective-C context, the author helps developers understand not just the “how” but also the “why” behind each algorithm. The repo is especially suited for developers working in the Apple ecosystem (Objective-C, Xcode) who want to build foundational knowledge in data structures and algorithms. By making the code accessible, it lowers the barrier to exploring algorithm performance, variant comparisons, and understanding underlying complexity. For learners, it offers a bridge between abstract algorithm descriptions in textbooks and real code you can compile, run, tweak, and visualize.
