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…
The Open-Closed Principle (OCP) represents the letter "O" in S.O.L.I.D. It teaches us to create software that is open to extension but closed to change, enhancing its maintainability and scalability. To be honest, the OCP is one of the most challenging S.O.L.I.D. principles to understand and apply in iOS projects.…
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…
How many responsibilities should a class have? As many as it needs! This is a common joke, but the reality often is far less amusing... How often do we encounter… “challenging” code annotated with "Do not change!!!" comments? Software development isn't rocket science. There are a few basic rules that most…
Picture this: you're just dying to play a car racing game. After a quick scroll through the App Store you find the perfect one. It has cool graphics and some sweet retro cars to race. And it's even free! You're pumped, hit download and wait. Finally, you launch the game…
Imagine you’ve just implemented a nice feature. Cleanly separated UI from business logic, added some unit tests, etc. Surely, code review would be a formality. Instead, this insufferable Senior Dev requested that you wrap one of the services with abstraction. Surely, you’ve read somewhere that you should operate on abstractions…
