swift-composable-architecture VS Cache

TCA for short. Very scalable, quite promising, quite popular. A decent alternative for MVVM enhanced by the Clean Architecture. You can learn more about it in a Point-Free tutorial and on GitHub.

🙏 Built with SwiftUI and The Composable Architecture (TCA): This isn’t a feature, but I just want to express my gratitude to the creators and maintainers of these two frameworks, which have played a huge part in making me fall in love with iOS development.

Razliciti alternativni frameworci i arhitekture - Recimo, na pamet mi padaju Composable Architecture (https://github.com/pointfreeco/swift-composable-architecture) i RIBs arhitektura (https://github.com/uber/RIBs). Ok, ove arhitekture resavaju neke probleme. Ali da li problemi koje te arhitekture resavaju solidan developer ne moze sam da resi bez vendor locka za kreatore tih arhitektura. Jesu one open-source, ali meni je rizik da se vezujem za bilo sta sto sutra moze da prestane da se odrzava.

I came across this post discussing MVM, MVVM, MVP, and composable architecture.

At a minimum, Composable Architecture, and now Dependencies from Point-Free.

I’ve built a couple of apps with this framework: https://github.com/pointfreeco/swift-composable-architecture

While there are apps that use a Redux-style architecture, the arch is still in its infancy in the community. There are a number of implementations each with their own take on Redux. TCA is probably the one with the most name recognition and documentation.

Learn it if the project at hand requires it. A lot of older, more mature apps will still use UIKit, so it’s likely if you plan to work an iOS developer job that you will need it. But it’s getting to the point where a lot of the forward thinking shops are already starting to integrate SwiftUI. (Me being one of them) which, btw, a lot of people will say SwiftUI isn’t quite there yet, and I mostly disagree. SwiftUI is good for a great many use cases. Yes, there are still pain points, but you can write most of the apps you’d need to write in SwiftUI. And there are great architectural frameworks out there that actually give SwiftUI an opinionated way to structure apps that is testable and maintainable.

For data storage, we have a caching layer that receives data from the cloud and stores it both in memory and on device. Then there is a pub model that notifies listeners when the data has been updated. it's pretty simple but works great! I like hyperoslo's implementation for cache: https://github.com/hyperoslo/Cache For units, we just build a protocol for the internet piece and provide the data locally. We cache the unit test data in a different folder on device and it all works seamlessly. I think the hardest part there was intercepting the HTTP requests and forking to the local test data. The key there was implementing a URLProtocol subclass.
