## Description

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 callbacks and allows for the interception of block calls at runtime to add logging or validation.

Additional capabilities include memory management tools to handle the manual copying and releasing of blocks between the stack and heap to prevent leaks. The toolset also supports dynamic block casting and pointer-based type conversion to enable generic block handling while preserving the original execution context.
