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.

Upload files

Using the REST API to upload a file to WordPress is quite simple. All you need is to send the file in a POST-Request to the wp/v2/media route.

There are two ways of sending a file. The first method simply sends the file in the body of the request. The following PHP script shows the basic principle:

This is a crash course in JavaScript. It is intended for people who already have a bit of programming experience in other languages.

This will hopefully give a basic idea of the most-commonly-used language features, but it is not indended to be a comprehensive guide.

This guide was last updated in August 2016.
