Question 1

How to implement MVVM in Swift using the App Architecture samples?

Accepted Answer

Examine the MVVM variant of the Recordings app in the repository; it shows a complete implementation with models, views, and view models. Compare it to other patterns to understand separation of concerns and data binding approaches in iOS.

Question 2

App Architecture book code vs other iOS architecture tutorials online?

Accepted Answer

This resource uniquely provides multiple patterns in the same app for direct comparison, unlike isolated tutorials. It's backed by a published book and video Q&A, offering more depth but may be less updated than community-driven content.

Question 3

Is this project useful for learning SwiftUI?

Accepted Answer

No, the samples are based on UIKit and traditional patterns, predating SwiftUI. For SwiftUI, look for resources focused on reactive or declarative architectures, as this doesn't cover modern Apple frameworks.

Question 4

What are the main differences between the seven Recordings app variants?

Accepted Answer

Each variant implements a distinct architectural pattern, such as MVC, MVVM, or others, showcasing how the same features—like recording management—are structured differently. The code highlights trade-offs in testability, complexity, and data flow.

Question 5

Can I use this code directly in my commercial iOS app?

Accepted Answer

While open-source, it's primarily educational; you can adapt ideas, but it's not a production-ready framework. Consider it a learning tool to inform your own implementations, as it may lack optimizations or scalability features.

Question 6

How to run the Recordings app variants in Xcode?

Accepted Answer

Clone the repository and open the .xcodeproj files in each variant's folder. Build and run to see the patterns in action; ensure your Xcode and Swift versions are compatible with the project's requirements.
