Mobile Development Platforms

1. Native Development platforms This platforms is divided into two:

• iOS Development: Languages: Swift, Objective-C Frameworks: UIKit, SwiftUI

• Android Development Languages: Java, Kotlin Frameworks: Android SDK

1. Cross-Platform Development Platforms This platforms includes building mobile applications that and be used in both Android and IoS platforms

Language: JavaScript
Framework: React Native

Language :Dart
Framework:Flutter

SOFTWARE ARCHITECTURE PATTERNS USED IN MOBILE DEVELOPMENT PLATFORMS WITH THERE PROS AND CONS

1. Model-View-Controller (MVC)
This Divides the application into three interconnected components which are:

• Model: Manages the data and business logic.
• View: Displays the data and sends user commands to the controller.
• Controller: Interprets user inputs and updates the model and view.

Pros:

• Separation of concerns making the code base easier to manage and test.
• Re-usability of the model and view components.
• Simple to understand and implement

Cons:

• Can lead to a "Massive View Controller" problem, where the controller becomes too large and complex.
• Tightly coupled components can make changes harder.

2. Model-View-Presenter (MVP)
This is an evolution of MVC where:

• Model: Manages the data.
• View: Displays the data and sends user actions to the presenter.
• Presenter: Acts as a middleman between the view and the model, handling all the presentation logic.

Pros:

• Better separation of concerns compared to MVC.
• Presenter is easier to test because it does not depend on Android/iOS framework components.
• Views are more focused on displaying data and less on handling logic.

Cons:

• Can result in a lot of boilerplate code.
• Presenter can become very large and complex.

3. Model-View-View-Model (MVVM)
This architecture divides the application into:

1. Model: Represents the data and business logic.
2. View: Displays the data.
3. View Model: Acts as a link between the view and the model, providing data to the view and handling user interactions.

Pros:

• Clear separation of responsibilities which makes the code easier to manage and test.
• Supports data binding which reduces boilerplate code in the view.
• View Model is easy to test because it does not depend on the view.

Cons:

• Can be more complex to implement compared to MVC and MVP.
• Data binding can add a layer of indirection, making debugging more difficult.

4. Clean Architecture
This emphasizes on separation of concerns by organizing the code into multiple layers:

1. Entities: Represent the core business logic.
2. Use Cases/Interactions: Encapsulate specific business rules.
3. Interface Adapters: Convert data from the use cases to a form that the external systems can use.
4. Frameworks and Drivers: External components like databases, UI, and external APIs.

Pros:

• High level of separation of concerns which makes the code base highly maintainable and testable.
• Each layer is independent, which improves code modularity.
• Facilitates easier testing of individual components.

Cons:

• Can be overkill for small projects.
• Involves a steep learning curve and more boilerplate code.
• Requires careful planning and design.
