What mobile app architecture should you choose for your project?

MVC (Model-View-Controller): Android/iOS: Simple, traditional architecture. Ideal for basic apps; native support on iOS. MVP (Model-View-Presenter): Android: Better for complex UIs, enhances MVC. iOS: Good for larger apps, improves UI logic and testability. MVVM (Model-View-ViewModel): Android: Recommended with Jetpack for reactive apps. iOS: Works well with SwiftUI and Combine for dynamic UIs.

This kind of architecture is more suitable for requirements where lot of interactions with device sensors etc are required, and where performance would need to be very high, e.g. high intensity multiplayer kind of games or some security related applications, etc. It's also a costly affair to use it, skill requirements, time required etc gets impacted. For typical mobile apps, whether it's shopping or banking or food order or some business workflow, none of these things are needed and a higher level access is sufficient for which other architecture paradigms and platforms are good enough.

You have 4 development platforms which help you to build applications for mobile. - Native Development Platform (Kotlin/Java for Android and Swift/Objective-C for iOS) - Cross-Platform Development Platform ( C# Xamarin/MAUI, JavaScript ReactNative, Dart Flutter) - Hybrid Development (JS PhoneGap, Ionic) - Multiplatform Development (Kotlin Multiplatform) We don't have a term called Native app architecture which doesn't clear the thought process and will lead to more confusion.

What does this have to do with "app architecture"? App architecture is about the structure of the software, not necessarily the target platform.

In iOS app development, combining the Model-View-Controller (MVC) architecture with the Coordinator pattern can help manage navigation and flow more effectively. Combining MVC with Coordinator - Each screen or logical section of your app is managed by a coordinator. - Coordinators handle navigation between view controllers, abstracting away the details from individual view controllers. - View controllers remain responsible for displaying data and handling user input, maintaining a clean separation of concerns. This way, the coordinator manages the navigation flow, and the view controller focuses on its specific responsibilities. The delegate pattern can be used for communication between the view controller and coordinator.

The decision-making process regarding the platform should align with the future business objectives of the product. Technical solutions should be a powerful tool on the path to the commercial success of the application, but not a challenge. When budget constraints dominate the game, opting for a cross-platform app development approach becomes a nice way out. In terms of growth potential, for instance, Flutter demonstrates exceptional promise by combining application performance and resource efficiency. It's a nice choice for MVP due to the faster development that, again, results in it generally costing 30%—40% less than native apps.
