Last night, I removed my app StreamToMe from the iOS App Store, after 9 years on sale. This will be a discussion about what it's like to have an app on the App Store that is financially successful but eternally problematic from a support and maintenance perspective. I'll talk about why I deliberately neglected my own product at times due to support costs and losing interest in the project. Finally, I'll look at why I've decided to simply pull it from the store – not open source it or sell it – even though it still works for many people. .

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 look at constructing Cocoa views in code using a unique syntax that offers dynamic and constant options with no syntactic overhead, support for parameters inherited through the class hierarchy, support for large numbers of optional parameters without needing to push unused parameters onto the stack, avoidance of parentheses, and avoiding the need to specify types – all while remaining completely typesafe.

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 present a small file for handling layout, similar to UIStackView or NSStackView but built around efficient Swift syntax and the aim of composing full layouts as a single expression.

A discussion about monads, whether Swift's flatMap is monadic, where you can use monads in Swift and where you can use some monad-like behaviors in Swift.

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.

There's an industry-wide push for protocol-oriented programming where shared interfaces, behaviors and substitutability are provided through protocols rather than subclasses. In this article though, I'll look at a case where I chose to use a subclass, instead of a protocol, to take advantage of some specific differences between classes and protocols.
