There are a number of different architectures that can be used for SwiftUI apps. Some of the most popular architectures include:
- MVVM: The Model-View-ViewModel (MVVM) architecture is a popular choice for SwiftUI apps. It separates the app's data (the model) from its presentation (the view) and its logic (the view model). This makes the app easier to understand, test, and maintain.
- VIPER: The View-Intent-Presenter-Interactor-Router (VIPER) architecture is a more complex architecture than MVVM, but it provides a more clear separation of concerns. It is a good choice for apps that need to be highly modular and testable.
- Clean Architecture: The Clean Architecture is a software architecture pattern that emphasizes separation of concerns, maintainability, and testability. It is a good choice for apps that need to be scalable and extensible.
- TCA: The Composable Architecture (TCA) is a newer architecture that is gaining popularity for SwiftUI apps. It is a simple and lightweight architecture that is well-suited for apps that need to be composable and declarative.
The best architecture for your app will depend on its specific requirements. If you are not sure which architecture to use, you can start with MVVM and then switch to a more complex architecture if needed.
Here is a table that summarizes the pros and cons of the different architectures for SwiftUI:

Ultimately, the best choice for your app will depend on its specific requirements and the experience of the team that is building it.
