OpenCombine
Open-source implementation of Apple's Combine framework for reactive programming, compatible with older Apple OSes and cross-platform.
What is OpenCombine?
OpenCombine is an open-source implementation of Apple's Combine framework, designed for processing values over time using reactive programming patterns in Swift. It solves the problem of using Combine's declarative API on platforms where Apple's native version is unavailable, such as older iOS/macOS versions, Linux, Windows, and WebAssembly. The project provides publishers, subscribers, and operators to handle asynchronous data streams seamlessly.
Swift developers building applications that require reactive programming across multiple platforms, including those targeting environments without native Combine support (e.g., pre-iOS 13, Linux servers, or WebAssembly projects).
Developers choose OpenCombine because it offers a reliable, API-compatible alternative to Apple's Combine, enabling consistent reactive programming patterns across all supported platforms without locking into Apple's ecosystem. Its modular design and conditional shim simplify multi-platform development while maintaining performance and debugability.
