Orange County . Today, we are going to know about traits which are a more clear, readable, intuitive and focused type of Observable.. A Completable is a variation of Observable that can only complete or emit an error. Thinking further, on one hand that makes sense because Observable.merge will also complete only once all of its Observables have completed; on the other hand, there used to be Completable.zip but apparently it was replaced by Completable.merge (with a chance of adding zip back someday according to #1245), and Completable.zip sounds more immediate as an operator to complete once all Completables have completed. It waits for a user input, and Embed. GitHub Gist: instantly share code, notes, and snippets. kakajika / flatMapCompletable.swift. GitHub Gist: instantly share code, notes, and snippets.
