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.

# This cheatsheet contains the most often used SFDX commands for beginners to get a jumpstart.
# Hint. it is highly recommended to use `-h` to check the usage of any SFDX commands and corresponding parameters.
# For instance, use `sfdx force:auth:web:login -h` to checke what `-d` `-a` parameters do

# List down all supported dx commands:
sfdx force:doc:commands:list

# Check current DebHub and Scratch Org status
