Project Overview

The goal of this project was to allow a user to view a dessert and corresponding instructions to make it. The data used was hosted by TheMealDB, and the frontend of this application was implemented using the SwiftUI framework.

Files

• /FetchRecipeApp: Contains the source code files of the iOS app.

  • FetchRecipeAppApp.swift: Main app file. Initializes all environment objects and invokes the launch screen.

  • /Models: Contains model file

    • MealModel.swift: Defines the data models and their operations. For this API I needed to create multiple models for each endpoint.

  • /ViewModels: Contains the file that defines the view model.

    • MealsViewModel.swift: Invokes a network call for each endpoint and hosts the data for all the desserts. Additionally takes care of formatting and filtering the data retrieved.

  • /Views: Contains all the views for the application

    • /LaunchScreen: Contains files for the launch screen

      • LaunchScreenView.swift: View that animates the application logo in an "ease-in-out-and-back-in" manner.

      • LaunchScreenManager.swift": Defines enum for launch screen phase as well as function to dismiss the launch screen animation.

    • HomeView.swift: Defines the view for the home page. Places each individual dessert in a mealRowView that will navigate you to the ingredients and instructions when tapped. Additionally has a filter button at the top.

    • MealRowView.swift: Defines the view for a row in the home page.

    • MealInsightsView.swift: Defines the view for the instructions and ingredients of a given dessert. Also contains the origin of the meal.

• /FetchRecipeAppTests: Contains unit tests for the ViewModel class

  • FetchRecipeAppTests.swift: Contains unit test for network calls. Can be improved with dependency injection. Tests the ViewModel methods as well

• /FetchRecipeAppUITests: Contains unit tests for UI. This portion is not completed and does not contain anything significant.

Acknowledgment

I would like to thank Nick from the Swiftful Thinking Youtube Channel and Tunde from the Tundsdev Youtube Channel. They taught me how to properly perform a network request via URLSession and how to write asynchronous unit tests.

Roadmap

For future iterations of this project, I want to implement a couple of things:

• Search feature and corresponding view that will take text from a text field and filter the list of meals based on that.
• Divide the home page in to different sections that include other categories besides desserts.
• Add a favorites section!
• UI Tests for the UI and all the views. Right now I do not know how to make them so I need more time to learn how to do that.
• Unit tests with dependency injection because my tests currently test the network itself (learned that I am not supposed to do that).
• Handle errors in a more sophisticated manner with a custom error class in the ViewModel.
