## Description

WinObjC is an implementation of the Objective-C language runtime and object model for the Windows operating system. Its primary purpose is to enable the execution of Objective-C code and iOS APIs on Windows to support the porting of iOS applications.

The project features a native API bridge that maps Objective-C system framework calls to native Windows API functions. It includes a toolchain to convert Xcode project targets and workspaces into Visual Studio formats and translates visual storyboard design files into active on-screen interface elements.

The codebase covers binary interoperability, multi-architecture compilation, and the routing of user interface events. It also provides diagnostic tools for inspecting runtime memory states and visualizing native objects during debugging.

Project outputs are distributed as NuGet packages.
