Notes

Notes is a collection of iOS note-taking applications demonstrating different architectural patterns. The repository includes implementations using both Model-View-Controller (MVC) and Model-View-ViewModel (MVVM) to illustrate best practices and trade-offs in iOS development.

Project Structure

The repository is structured as follows:

Notes/
│── MVC/
│   ├── NotesAppMVC.xcodeproj
│   ├── ...
│── MVVM/
│   ├── NotesAppMVVM.xcodeproj
│   ├── ...

Architectural Patterns

Model-View-Controller (MVC)

Overview

MVC is a widely used architectural pattern that separates the application logic into three main components:

• Model: Manages the data and business logic.
• View: Handles the user interface.
• Controller: Acts as an intermediary between the Model and the View.

Pros

✅ Simple and familiar to most iOS developers. ✅ Quick to implement for small projects. ✅ Direct integration with UIKit components.

Cons

❌ Often leads to "Massive View Controllers" due to business logic creeping into controllers. ❌ Difficult to maintain and test as the project scales.

Model-View-ViewModel (MVVM)

Overview

MVVM improves upon MVC by introducing a ViewModel to better manage data transformation and business logic:

• Model: Manages the data and business logic.
• View: Handles the user interface.
• ViewModel: Acts as an intermediary, preparing data for the View and handling user input logic.

Pros

✅ Improved separation of concerns, leading to better maintainability. ✅ Easier to test, since the ViewModel is independent of UIKit. ✅ Works well with SwiftUI and reactive programming (Combine, RxSwift).

Cons

❌ More complex than MVC, requiring additional boilerplate code. ❌ Can be overkill for simple applications.
