## What it is
The Windows Bridge for iOS (WinObjC) is a Microsoft open-source framework providing an Objective-C development environment for Visual Studio with support for iOS APIs. It lets developers reuse Objective-C code to build Universal Windows Platform (UWP) apps that run on Windows 10 devices.

## Use cases
- port an iOS app to Windows without rewriting it in C#
- compile Objective-C code on Windows using Visual Studio
- build UWP apps from existing iOS codebases
- reuse iOS API calls in a Windows application
- bring an Objective-C library to the Windows platform

## When to choose
- you have an existing Objective-C iOS codebase and must target Windows 10 UWP
- you want to reuse iOS APIs and Objective-C tooling inside Visual Studio

## When to avoid
- you are starting a new cross-platform project - modern options like .NET MAUI, Flutter, or React Native are actively maintained
- you need to support current Windows versions beyond UWP or recent iOS APIs
- you require long-term support or community updates
