This article is about adding a separated Services-layer to an app. A Services-layer is, in my opinion, the single best app architectural addition you can make, after the basic Model-View separation already implicit in SwiftUI. Where...

In the previous article, I looked at how SwiftUI’s data-driven changes force a basic separation between Model and View. The separation is limited in scope, requiring only that there exist a state value or observable object that...

In the previous article, I wrote a simple SwiftUI app. During the writing, I deliberately kept the code simple – writing code only when needed to satisfy user-facing goals. I want to take a closer look at the application architecture that...

In this series of articles, I’ll look at fundamental app architectural concepts and how they apply to an app written in SwiftUI. To begin the series, I want to start with something small: a JSON feed reader app in SwiftUI. I want to...

I wrote some experiments around Combine, Apple’s reactive programming framework, to gain insight into how Combine handles edge cases that have caused problems for me in other reactive programming frameworks. Looking at everything in...

A little over a month ago, I released CwlViews and then followed up with an article suggesting that Apple might be about to release their own declarative views library. At WWDC this week, they did just that, releasing SwiftUI. This article...

In the previous article, I released CwlViews. Its key feature is a unique take on “declarative views”. Most modern approaches to view frameworks use some form of declarative view construction. This has slowly evolved from...

CwlViews replaces the diverse collection of construction and management interfaces in Cocoa with a set of composable, declarative “binding” constructors. The result hides much of the busywork that dogs Cocoa application...

Over the last month or two, I’ve been slowly updating Cocoa with Love Swift projects and articles to Swift 4.2, Xcode 10, iOS 12 and mac OS 10.14. In a year without any massive new features or obvious changes to Swift, it’s...

Last night, I removed my app StreamToMe from the iOS and Mac App Stores, after 9 years on sale. It’s a deeply sad experience for me – like I’ve lost a faithful pet – so I wanted to write a quick retrospective. This will be a...
