Swift Concurrency Manifesto

Swift Ownership Manifesto TL;DR

Most of the manifesto is background and detailed definitions -- if you're confused or want details, read the manifesto!

Note also that manifestos aren't complete proposals -- syntax and details may change!

One piece of background: inout is kinda complicated because it can be used on computed properties -- foo(&val.x) might be sugar for

Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Conversion Process from Objective-C syntax to Swift The most important first step is to run Apple's "Convert to Modern Objective-C Syntax" refactoring, so that you're using array/dictionary literals and bracket-accesses; these will then be usable in Swift. Note also that I'm a beginner in Swift, so my apologies for any mistakes or incompleteness here.

When you see this pattern	Replace with this
Module
`@interface newType : superType <protocol1, protocol2>`	`class newType : superType, protocol1, protocol2`
`@implementation` OR `@synthesize` OR `@end`	Delete

	guard let url = URL(string: todoEndpoint) else {
