## What it is
An open-source book and reference documentation on Apple's Combine framework, with notes on using it alongside SwiftUI and UIKit. It includes commented sample code, marble diagrams, recipes, and an Xcode project with playgrounds and tests, published as hosted HTML, PDF, and EPUB.

## Use cases
- learn apple combine framework
- swiftui combine tutorial
- understand publishers and subscribers in combine
- combine dataTaskPublisher network request examples
- test combine publishers with xctest
- integrate combine with uikit ui updates

## When to choose
- you are learning or referencing Apple's Combine framework for iOS/macOS development
- you want free, well-organized reference docs with sample code and diagrams
- you need recipes for common Combine patterns like error handling, networking, and UI binding

## When to avoid
- you need documentation for third-party reactive libraries like RxSwift or ReactiveSwift
- you want a maintained library or code dependency rather than learning material
- you need up-to-date coverage of newer Apple async/await concurrency approaches

- maturity: maintenance
- function: documentation, developer-tools
- domain: developer-tools, tutorials, mobile-development, frontend
