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…
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…
The early (and also not-so-early) days of building a tech startup means hiring and working with people who are capable of wearing a lot of hats. There are a ton of things to do and nowhere near an equal amount of resources to do them. Even if you join as a specialist, chances are you’ll…
Throughout my life, I have met several people who struggle to learn a new language, with some of them being unable to communicate at a basic level despite having studied for several years. I believe that learning a language is not a matter of talent, but that of dedication and following a good process. In…
Working at a large company like Apple or Google is such a common goal in the tech industry that there’s even a market for selling courses and books designed to help people achieve this goal. But one thing that I’ve learned in my career is that working at such companies is not for everyone. The…
Passkeys are an alternative to passwords that allow you to sign in to any website or app that supports this technology without needing to define/remember a password. Over the last couple of years, the tech world has been witnessing many companies updating their products to add support to this new technology, including tech giants like…
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 that I still find…
As an app’s code base grows and evolves, it can be really tricky to maintain consistency within its UI. It’s easy for things like margins and padding, or colors and fonts, to start diverging, as different developers might use different values within each individual UI component’s implementation. At the same time, UI code can also…
In Swift, the @MainActor attribute can be used to associate a given type, function, or value with the global main actor, which essentially makes any such code operate on the enclosing app’s main thread. That’s incredibly useful for things like UI-related code, since UI updates (whether done using UIKit, SwiftUI, or another framework) most often…
New in Swift 6.4 (which at the time of writing is in beta as part of Xcode 27) is a warning which is emitted when a nested closure performs a weak capture while the parent closure implicitly captures that object as a strong reference. At first glance, that new diagnostic could be a bit puzzling,…
