Combine is Apple's native framework for handling asynchronous events, network calls, and state management in iOS/macOS apps. Essential for modern Swift development and directly competes with RxSwift.

Combine Framework Appleずは

Combine is Apple's framework for composing asynchronous and event-based code using a declarative, functional approach. It provides publishers, subscribers, and operators to handle network requests, user input, and state changes in a unified, testable way. Combine is the backbone of modern iOS and macOS development. Combine is essential for anyone developing production iOS/macOS applications. It simplifies asynchronous code, reduces callback hell, and integrates seamlessly with SwiftUI. Understanding Combine is a strong competitive advantage in the Apple development job market and is expected for senior iOS roles.

❓ よくある質問

▶What is the difference between Combine and RxSwift?
Combine is Apple's official framework while RxSwift is third-party. Combine is optimized for Apple platforms, integrates tightly with SwiftUI, and is the recommended path forward.
▶How do I handle errors in Combine pipelines?
Use operators like catch, tryMap, and assertNoFailure. Always specify error types in your publisher declarations.
▶What are the main operators I should master first?
Start with map, filter, flatMap, combineLatest, merge, and debounce. These cover 80% of common use cases.
▶How do I test Combine code?
Use XCTestDynamicOverlay, Mock publishers, and sink to capture values. The Combine Testing framework provides additional utilities.
▶When should I use CurrentValueSubject vs PassthroughSubject?
Use CurrentValueSubject when you need to replay the latest value; use PassthroughSubject for events that don't need history.
▶How does Combine integrate with SwiftUI?
SwiftUI's @ObservedObject and @StateObject properties work seamlessly with Combine publishers, making reactive UI straightforward.
▶What are backpressure and demand in Combine?
Demand signals how many values a subscriber is ready to receive. Backpressure ensures subscribers aren't overwhelmed by rapid event sequences.
