A series of articles on SwiftUI application development — SwiftUI was introduced at WWDC 19 and launched with iOS 13. Since its introduction SwiftUI has generated a ton of interest, a bit of controversy, and a lot of articles. Including my own. I’ve written rather extensively on SwiftUI, on SwiftUI application architectures, and on issues and hidden gotchas that…

Just a list of Medium articles published in 2022, gathered all in one place. — Factory: Circular Dependency Chains * How to find and eliminate them Another ChatGPT SwiftUI Session Exploring the future of conversational programming. ChatGPT and SwiftUI Not that I’m worried, but… Factory: Multiple Module Registration How to initialize everything before anything is initialized. SwiftUI Binding Extensions

Or how I reached 100% code coverage in Factory. — I wrote an earlier article on the importance of unit testing in a library and I still believe that it’s a best practice. And doubly so when that library is a critical piece of code on which an entire application depends. The library in question is Factory, a compile-time safe…

Or what happens when one size doesn’t fit all? — Anecdotal software development is defined as an over-reliance on personal experience or opinion when designing and building software. You’ve probably have never heard it put quite this way before, but this is how the majority of people write and develop software. …

How to find and eliminate them — Dependency Injection systems like Factory can help make your code easier to write and test. But occasionally problems will arise, and one of the more common issues we see in DI systems relate to circular dependencies. What’s a circular dependency? Let’s say that A needs B to be constructed, and B needs a C…

Exploring the future of conversational programming. — I wrote an earlier article on ChatGPT where I asked it to build a SwiftUI form based on a handful of parameters… and it did. And when asked it also added some error handling and property marshaling for good measure. So I’ve been working with it for a few days…

Not that I’m worried, but… — ChatGPT is a demonstration project by OpenAI that can converse on a number of topics. Including programming. Let’s take it through its paces, shall we? ChatGPT Conversation Everything that follows from this point forward is my input prompts, followed by ChatCGP’s responses, complete with sample code. Hey ChatGPT, can you make a…

How to initialize everything before anything is initialized. — When you want to use a dependency injection system like Factory with multiple modules you often run into a “Who’s on first” dilemma. Let’s say that ModuleP specifies an abstractAccountLoading protocol. // ModuleP public protocol AccountLoading { func load() -> [Account] } Moving on, we have an accounting module, ModuleA…

Making binding in SwiftUI views and previews as easy as ABC — Here are a few common SwiftUI issues that fall into the “there has to be a better way” category. Optional Values Let’s begin with optionals. It’s common to have optional values in our code due to API requirements, but working with them in SwiftUI can be a bit of a pain. Consider. …
