This is an iOS test assignment for the STRONG TEAM Summer Internship. The goal is to develop a Geographic Atlas iPhone application that allows users to learn more about world countries, browse a list of countries grouped by parts of the world, and view detailed information about any country.

Demo Video.

You can go through scrollable list of all the world countries grouped by parts of the world. Each element in the list able to switch between expanded/collapsed states when the user taps on the element. By tapping the “Learn more” button in the expanded element state, screen will provide the detailed information of the currently selected country.

To install and run the app, follow these steps:

1. Clone the repository to your local machine using the following command:

$ git clone https://github.com/meruyert123/Geographic-Atlas.git

2. Open the project in Xcode by double-clicking the .xcodeproj file.
3. Select a simulator or a connected device from the Xcode toolbar.
4. Click the "Run" button (or press Cmd+R) to build and run the app on the selected device.
5. The app should now launch on the simulator or connected device you selected.

This project follows the MVVM (Model-View-ViewModel) architecture pattern. The MVVM pattern separates the user interface (view) from the business logic (view model) and the data (model) to improve code organization, reusability, and testability.

• Models: Contains the data structures or entities used in the application. These models encapsulate the data and business logic related to them.

• Views: Responsible for presenting the user interface.

• Components: Reusable UI elements or widgets that can be used across different views.

• Data: Handles data retrieval, storage, and manipulation. This layer may include services, repositories, or APIs for managing data operations.

• View Models: They retrieve data from the data layer, perform any required transformations or computations, and update the views accordingly.

1. Use SwiftUI only
2. Use “skeleton views” for all the elements while API requests are performed
3. Make the expand/collapse feature for CountriesList animated, with no UI bugs
4. Add the images caching and reuse them from cache
5. Use “nice” naming
6. Follow MVVM architecture
7. Write safe code, leave no possibility of crashes
8. Make the “Capital coordinates” latitude + longitude value on the CountryDetails screen tappable;
