Yi amfani da async/await don one-shot asynchronous work da sakamako guda (network call, karanta file); yi amfani da Combine (ko AsyncSequence) don streams na values a kan lokaci — UI events, debounced search text, ko continuous updates. Suna warware siffofi daban-daban na matsala, kuma code na zamani sau da yawa yana haɗa su.
Task yana soke children ɗinsa).map, debounce, combineLatest), da backpressure da declarative composition.// Combine: a live, transformed stream — perfect for search-as-you-type

.receive(on: RunLoop.main)
.assign(to: &$results)
// async/await: a single fetch — linear and readable

}
Ba ka cika bukatar dukkan injin Combine yanzu. AsyncSequence da for await suna rufe streaming cases da yawa a asali, kuma za ka iya haɗawa: publisher.values yana fallasa Combine publisher a matsayin AsyncSequence.

Manyan masu tambayoyi suna son ganin ka daidaita siffar data — value guda da stream — da abstraction ɗin da ya dace, kuma ka san async/await yanzu shi ne tsohuwa.
