You're deep in a tricky bug when Slack pings: a colleague needs a code review. You sigh and click through. 47 files changed. 2,800 lines added, 400 removed. The size of the commit suggests the code wasn't written entirely by hand. That suspicion is confirmed the moment you start scrolling.…
So, you've finally convinced stakeholders to raise the deployment target from iOS 15 to iOS 17 - and the first thing on your mind is @Observable. You've read the docs, watched the WWDC sessions - it looks like a straightforward swap. Replace ObservableObject, drop the @Published wrappers, change @StateObject to…
If you've cared about code quality and consistency before AI-assisted coding became standard, you surely understand the pain of setting development standards in the team. It's an endless cycle: writing documentation that nobody reads, explaining conventions everyone forgets, and leaving the same code review comments for the hundredth time... Finally,…
Imagine you've just built an amazing iOS app for a restaurant. The client loves it, the users love it, their dogs love it, etc. As expected, soon enough you get a call from the client: Hey, can you make the same app for my other restaurant? Sounds simple. Just copy-paste…
Over the years, we've been told to use dependency injection to help our apps scale better. On the other hand, design patterns like MV suggest simplifying app design to the minimum, often overlooking proper dependency management. While most of us instinctively understand that Dependency Injection is crucial for maintainability, testability,…
Remote styling in iOS apps is becoming increasingly important for modern development workflows. Picture this: you're finalizing a banking app with remote UI configuration capabilities. From the project's inception, you've implemented a robust remote styling system with SwiftUI view modifiers that make UI updates seamless. Your codebase includes well-structured style…
Recently, modularity has gained a lot of popularity in our field over the years. Architectures like TCA and VIPER pride themselves on their inherently modular design. Compared to a monolithic design, modularity offers various benefits: efficient work parallelization (especially in large teams), interchangeability, superior separation of concerns and responsibilities, and…
What distinguishes a top 10% iOS developer? How can we draw parallels with the craftsmen of old? In what ways can we refine our skills following their lead? How should we select our projects, clients, and companies? Once involved in a project, how do we initiate change to ensure its…
Although SwiftUI is a great framework, it’s not without its limitations. If you’ve ever had to implement a complex application, utilizing branching navigation flows, you probably know what I am talking about. Yes, navigation components in SwiftUI have been a constant source of headache… An iOS 16 addition, the NavigationStack,…
The benefits of having an exhaustive automated tests suite are obvious to anyone who ever worked on an app for more than a few months. We’ve all seen what lack of code maintenance might do: duplication, hidden side effects, convoluted business logic. A project codebase is like a garden -…
