This article will look at how SwiftUI's approach to declarative views compares to CwlViews, why the two approaches differ and what Apple changed to make this possible. I'll end with some thoughts about how this will affect macOS and iOS development.
In this article, I'll look at the the biggest problem with non-declarative views and how frameworks have slowly become more declarative, over time. I'll take a guess at what approach a declarative view framework from Apple might use – although keep in mind, I have zero insider knowledge and there's only a month before WWDC proves how wrong I am.

CwlViews is a library that offers declarative construction for all common iOS and macOS view and application objects. The result hides many of the busywork tasks that consume much of Cocoa application programming, leaving behind a highly concise, declaratively constructed, view-state driven, reactively connected experience.

The upcoming CwlViews library offers a syntax for constructing views that has a profound effect on the Cocoa applications, making them naturally 'unidirectional' and eliminating the need for `UIViewController` subclasses. In this article, I look at what the Cocoa application design pattern becomes if we take away the need for a controller.

In this article, I'll look at View-state; a frequently ignored trait in typical MVC programs. I'll explore how treating View-state as a Model can lead to simpler navigation transitions, better debug logging, easier state restoration and tricks like time-travel.

In an effort to explain what effects application design patterns have on code, I deliberately write an application using the worst possible application design pattern, in the hope that obvious mistakes will reveal the benefits of using better patterns.

I show how to structure programs around three tiers of computational units – statements, messages and reducers – and talk about the general problem of containing and isolating state that this restructuring aims to address.

In this article, I’ll look at a little theory and history behind the primary application design pattern used in Cocoa. I’ll discuss the key shortcoming of Cocoa’s Model-View-Controller approach, Apple’s aborted efforts to address this shortcoming and wonder from where the next major improvements will come.
