The Entry macro reduces the boilerplate when customizing the SwiftUI environment. Creating New Environment Values – A Recap Adding our own values to the SwiftUI environment is a common operation but it requires some boilerplate code each time. See SwiftUI Custom Environment Values for an example but here’s a quick recap: Create the environment key […]
Every year I watch WWDC and write down some notes. But I’ve just realized that I’ve never shared those notes and it felt like something I should do, so I’ve decided to do just that! My approach is to pick a handful of sessions that are immediately useful / interesting to me and ignore the […]
Disclaimer: The trick I’m going to show here is quite powerful, but like every other underscored attribute in Swift, this is something you should avoid messing with unless you know exactly what you’re doing. There are lots of pitfalls attached to these attributes, and the behavior of underscored attributes can change at any time and […]
Software engineering book recommendations The following is a list of software engineering books I’ve read that I felt had a strong and lasting positive impact on my career. It’s not a list of everything I enjoyed (that would be impossible to list down), but rather a special list of resources that taught/helped me so much […]
Have you ever seen “preachings” like these in the wild west of Twitter, Medium, and LinkedIn? “If you’re not using X in 2023 you’re an idiot!” “XYZ architecture is the only way to go!” “Doing X in Swift?

async/await in Swift was introduced with iOS 15, and I would guess that at this point you probably already know how to use it. But have you ever wondered how async/await works internally? Or maybe why it looks and behaves the way it does, or even why was it even introduced in the first place? […]
Performance problems can be rare in this era of blazing-fast iPhones, but chances are you’re still having to deal with them every once in a while. Classic performance issues such as scroll hitches are still very easy to introduce if you’re not careful about them, and when it happens, you’ll want to be properly equipped […]
If you landed at this article then it’s possible that you’re dealing with one of the most annoying things you can face as a developer: having to investigate an issue reported by your users that nobody seems to be able to reproduce internally. The topic of investigating crashes you can’t reproduce is something I’ve already […]
I had played with SwiftUI sporadically in the past, but it wasn’t until now that I had built a complete App Store-ready app with it. When SwiftUI was first announced I was very concerned about certain quirks of the framework and how it was probably not suitable for professional iOS development, but with the framework […]
