iOS System Design with SwiftUI & MVVM | Salary Calculator App

System design is a must-have skill for iOS developers — not only for building scalable apps, but also for interview preparation.

In this video, we’ll walk through the system design of a real-world Salary Calculator app using SwiftUI, MVVM, and clean architecture. This is just one piece of the full app, but it will give you a solid understanding of how to structure your iOS projects like a pro. 🚀

📚 Want to go deeper?
I’ve created a full course where we build this app from scratch in SwiftUI + MVVM. In it, we cover everything from UI to data management — applying the same best practices shown here, but in much more detail.
