Concrete proposal for async semantics in Swift

Async/Await for Swift


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.

Created Jul 31, 2014
Rotate Keynote Document for use as an app Prototype
View RotateKeynoteDocumentDroplet
// Open Script Editor and Export this as an Application
// Then drop a keynote file on it in the Finder and it will properly resize
// and rotate everything so the Keynote file becomes usable as a prototype
// in the iPhone keynote app
// rotateDocument exported function
// Accepts a Keynote document and will rotate
// all the slides and elements in the slide 90 degrees
You can’t perform that action at this time.
