Libextobjc

libextobjc is an Objective-C language extension library and runtime toolset that provides functional programming patterns and advanced dynamism. It functions as a collection of utilities for method injection, class reflection, and static analysis to help prevent runtime crashes.

The library enables the generation of algebraic data types at compile-time and provides a mechanism for synthesizing backing instance variables for properties defined within categories. It also implements protocol default behaviors and provides tools for validating key paths and selectors during the compilation process.

The project covers broader capability areas including asynchronous flow control through block-based coroutines and memory management utilities that automate resource cleanup and mitigate reference cycles within block scopes. It further includes tools for runtime method injection and object reflection to analyze class hierarchies and properties.

    BlocksKit is a low-level utility library for Apple platform development, specifically designed for managing the execution flow and memory of blocks within macOS and iOS applications. It provides a collection of helper functions to simplify the use of blocks in Objective-C and C, reducing boilerplate code and addressing inherent technical limitations. The library focuses on bridging Objective-C blocks with legacy C-based APIs by providing compatible wrapper structures and function-pointer emulation. It enables the passing of blocks through system interfaces that require strict C-style callback

    fp-ts is a TypeScript library that brings pure functional programming patterns to the language through algebraic data types, type class abstractions, and composable combinators. It provides foundational data types like Option for optional values, Either for typed error handling, and Task for lazy asynchronous computations, all designed to make invalid states unrepresentable and side effects explicit. The library is built on category theory concepts, offering type classes such as Functor, Applicative, Monad, Semigroup, and Monoid with lawful instances for common data structures. The library di

    Kiwi is a behavior-driven development framework and specification library for iOS. It functions as a wrapper for XCTest, allowing developers to define and execute software requirements as automated tests to verify application logic. The framework utilizes a domain-specific language to organize test cases into a nested hierarchy of descriptions. It includes a mocking system that employs runtime message interception and dynamic proxies to record invocations and return stubbed values. The system provides a fluent assertion interface to evaluate object states and uses a block-based engine to exe
