An open-source Swift implementation of Apple's Combine framework for reactive, value-over-time processing. It enables Combine-compatible code on older Apple OS versions and on Linux, Windows, and WebAssembly.

Use cases

• use Combine-style reactive programming on Linux or Windows
• write Combine code for iOS apps supporting versions before iOS 13
• share reactive Swift code across Apple and non-Apple platforms
• run Combine pipelines in WebAssembly targets
• use Combine operators like debounce and receive(on:) with DispatchQueue schedulers
• bridge NotificationCenter and URLSession publishers through a Combine-compatible API

When to choose

• you need Combine compatibility on platforms or OS versions where Apple's framework is unavailable
• you want a dependency-free reactive core with optional Foundation/Dispatch integrations
• you build cross-platform Swift apps and want one import (OpenCombineShim) that re-exports Combine where available

When to avoid

• you target only macOS 10.15+/iOS 13+ and can use Apple's built-in Combine
• you need a full async/await or RxSwift-style ecosystem rather than Combine parity
• you rely on CocoaPods and need the OpenCombineShim module, which is SwiftPM-only
