Async/Await for Swift

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.

Add a command to Finder services in Mac OSX to open a folder in VS Code
View Mac OS X: Open in Visual Studio Code
- Open Automator
- File -> New -> Service
- Change "Service Receives" to "files or folders" in "Finder"
- Add a "Run Shell Script" action
- Change "Pass input" to "as arguments"
- Paste the following in the shell script box: open -n -b "com.microsoft.VSCode" --args "$*"
- Save it as something like "Open in Visual Studio Code"
