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…

Want to ace that common interview question? — Do enough interviews and you’ll no doubt hit one of the most common iOS development interview questions. We’ve all been there. The interviewer, no doubt a senior iOS developer with a glint in his eye, hands you a piece of paper and says, “Okay. …

Yes, it’s pretty much what you think. — So I was taking a break, browsing Medium to see if anything was new, different, or exciting, and I came across an article whose headline discussed returning data from an asynchronous Swift function. “Cool!” I thought. (Hey, to me such things are exciting. Deal with it.) In fact, this particular…

Relying on the Xcode Rosetta hack? Then you’re in trouble. — Just saw this in the official Xcode 14.3 beta release notes. Deprecations Xcode isn’t supported under Rosetta. See Developer Technote's “Resolving architecture build errors on Apple silicon“ for more information. (92772361) If you’re an app developer and this means nothing to you, then great! But if you saw this and those…

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…
