Async semantics proposal for Swift

Modern Cocoa development involves a lot of asynchronous programming using blocks and NSOperations. A lot of APIs are exposing blocks and they are more natural to write a lot of logic, so we'll only focus on block-based APIs.

Block-based APIs are hard to use when number of operations grows and dependencies between them become more complicated. In this paper I introduce asynchronous semantics and Promise type to Swift language (borrowing ideas from design of throw-try-catch and optionals). Functions can opt-in to become async, programmer can compose complex logic involving asynchronous operations while compiler produces necessary closures to implement that logic. This proposal does not propose new runtime model, nor "actors" or "coroutines".

Senior Swift Backend Developer (Freelance, 100% Remote)

I am searching experienced backend developers (freelance, remote) with a ❤️ for Swift for Moonshot Energy, the world’s first AI-driven renewable energy company located in Germany. Moonshot Energy is financially backed by Innogy SE, one of Europe's largest energy providers.

At Moonshot you will play a major role in making the world greener, the future brighter and energy distribution smarter by using latest technologies like server-side Swift, microservices, artificial intelligence 🤖 and machine learning and new interfaces like chatbots and dialog-based systems (NLP).

Since our team is working on European timezones it would be good if you would live in the EU or if you are an early bird living in US-East 🇪🇺🇺🇸.

Your job:

• build our internal microservices

Async/Await for Swift

• Proposal: SE-XXXX
• Authors: Chris Lattner, Joe Groff

Introduction

Modern Cocoa development involves a lot of asynchronous programming using closures and completion handlers, but these APIs are hard to use. This gets particularly problematic when many asynchronous operations are used, error handling is required, or control flow between asynchronous calls gets complicated. This proposal describes a language extension to make this a lot more natural and less error prone.

This paper introduces a first class Coroutine model to Swift. Functions can opt into to being async, allowing the programmer to compose complex logic involving asynchronous operations, leaving the compiler in charge of producing the necessary closures and state machines to implement that logic.
