FetchMeal

Dessert recipes IOS application

Description

This is an iOS application that allows cooking enthusiasts to browse dessert recipes fetched from a remote API. The recipes are sorted alphabetically, and users can search for a specific recipe using a search window. Clicking on a recipe displays a detailed description, including ingredients, in a new window. Users can mark recipes as favorites, which are saved in user defaults and persist across app restarts

Getting started

  1. Make sure you have the Xcode version 14.0 or above installed on your computer.
  2. Download the FetchMeal project files from the repository.
  3. Open the project files in Xcode.
  4. Click Run Buttong in Xcode You should see a screen with a title Desserts.

Usage

To find a recipe that you like, you can either scroll through the list of recipes or simply type its name in the search bar. Once you find a recipe you want to learn more about, click on it and you will be redirected to the details view where you can see a detailed description, ingredients, and measures.

If you want to save a recipe for later, scroll to the bottom of the detailed description and tap on “Add to Favorites”. A small red heart will appear next to the recipe in the main menu to indicate that it has been bookmarked. You can remove the bookmark using the same method. Your chosen bookmarks will remain saved even when you exit and restart the app.

Arhitecture

  • Design Pattern The app is designed using the MVVM architecture pattern, which offers numerous benefits for the project. By utilizing this pattern, the app benefits from low coupling and high cohesion, as well as a clear separation of concerns. This, in turn, makes the codebase easier to test, maintain, and expand over time.
  • Async/await The API Service uses the async/await mechanism to make API calls, which guarantees that we exit the asynchronous function only once and reduces the risk of common errors found in closure-based asynchronous code. By utilizing async and throw, we are moving risk to compile-time, which leads to less error-prone code. This approach provides improved readability and locality, compile-time checking, and better testability.
  • Generics The API Service has been implemented as a generic function that can be used to retrieve all meals or details of a meal by ID. By implementing the API Service in this way, it improves code conciseness and promotes reusability. This is because the same function can be used in multiple parts of the application to fetch data, rather than having to write separate functions for each endpoint.
  • Protocols The API Service is designed to implement a protocol, which will allow for easy integration with other components in the future. By using a protocol, the API Service can be easily mocked or replaced during testing. This makes the code more flexible, maintainable, and easier to modify in the future. Additionally, the protocol design promotes adherence to the single responsibility principle, as the API Service is responsible only for implementing the protocol methods, and not for handling any implementation details.

Tests

The application currently includes tests to ensure basic functionality of the APIs. In future releases, additional tests will be implemented using mock objects to further improve test coverage and ensure the reliability of the application.
