Asynchronous Programming with Combine
summary
Apple’s Combine is a declarative Swift API for streams: code shows concrete use of URLSession dataTask publisher, timers, NotificationCenter and KVO publishers, plus map/filter/scan, combineLatest and catch for errors. Pipelines return concrete publisher types often erased with eraseToAnyPublisher; subscriptions produce AnyCancellable stored in a set or via store(in:). Examples show debouncing, parallel requests, cancellation and transforming failures; Combine runs only on recent Apple OSes and is early-adopter ready.
