Real World Swift

In this episode, we break down Feature-Oriented Architecture on iOS and how it scales real-world apps by slicing them into modular, independent features. We’ll talk about how FOA complements patterns like MVVM, TCA, and Clean Architecture, so you get both vertical feature modules and clean horizontal layers for testability and maintainability, and we'll demonstrate the concept using an example To-Do app that manages to-do "task" objects. By the end, you’ll have a mental model you can apply directly to your own production codebases.

On stage, SwiftData looks magical; in the wild, it has opinions. In this episode of Real-World Swift, we talk about wiring SwiftData into real world system designs, using patterns like MVVM, Repositories, and layered data stacks that need to be testable and scalable. If you’re tired of sample projects that never mention DI, test doubles, concurrency, or performance, this conversation will help you design a SwiftData setup that can actually survive in the wild.

This episode dives into the practical applications of the Swift Concurrency concepts we covered in Part 1 of this series.

In our pilot episode, we have a conversation exploring Swift's modern concurrency model, built on async/await and Structured Concurrency, which fundamentally re-architected asynchronous programming for cleaner, safer code. We detail how this system eliminates hard-to-debug data races using Actors for serialized state access, leveraging Swift 6's strict concurrency checking to enforce data safety at compile time.
