Project Architecture

The project follows the MVC (Model-View-Controller) architecture, which is common in iOS development:

1. Model:

   • Responsible for representing the data and business logic. In the context of login, the Model handles information like user credentials and validation.

2. View:

   • Responsible for the graphical user interface. Storyboards and xibs are used to design the login screen and success/error messages.

3. Controller:

   • Acts as an intermediary between the Model and the View. For login, the Controller captures user interactions, processes data, and updates the interface as needed.

Features Implemented

• Login with Email and Password: Local credential validation and server integration.
• Simple and Functional Interface: Minimalistic design using UIKit.
