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.

From episode "5 - Setting Up Universal Links (Deep Linking)" on the Inside iOS Dev Podcast

1) Create an apple-app-site-association file that contains JSON data about the URLs that your app can handle.

• Create apple-app-site-association text file without .json file extension
• Use application/json MIME type for the text file
• Have the following contents of the file similar to this format:

   {
   	"applinks": {

"apps": [],

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
