Combineのasync/awaitをライブラリ化して自作フレームワークで使ってみた。かなり良い感じ。 https://github.com/rizumita/CombineAsync #CodePiece

CodePiece.swift

static func update(event: Event, context: Context) -> Async<Model> {
        async { yield in
            switch event {
            case .increase:
                context.countRepository.increase()
                
            case .increaseAutomatically:
                yield(context.countRepository.increaseAutomatically(interval: 2.0, until: context.until)
                    .flatMap { self.makeModelAsync(context: context) })
                
            case .stopIncreaseAutomatically:
                context.until.send(())
                
            case .decrease:
                context.countRepository.decrease()
            }
            
            yield(makeModelAsync(context: context))
        }
    }
