How to Dynamically Display Console Categories in SwiftUI Using Navigation Links

If you're a newcomer to SwiftUI and are building an app to organize and showcase Nintendo consoles, you might face challenges when trying to create a menu that only displays relevant items based on the category selected. In this guide, we’ll walk through how to efficiently manage categories and display specific console details, making your app better structured and user-friendly.

Understanding the Problem

You're developing an app that holds various Nintendo console details. Within this app, you’d like to keep consoles categorized on the main menu. However, there's difficulty in making the console menu display only the consoles that correlate to the category tapped on the main navigation bar.

Here's a quick overview of the situation:

You already have set categories based on the consoles in your array.

Despite having this structure, you struggle to display only the respective consoles in the console menu for the chosen category.

Solution Overview

By following a few essential modifications to your SwiftUI code, you can make the menus work as desired. The key idea is to pass only relevant consoles to the console menu based on the category selected from the main menu.

Step 1: Modify MainMenu Structure

Start by altering how you list your categories in the MainMenu. Instead of displaying all consoles, focus on providing the category value to the next view (ConsoleMenu) directly.

Here’s how the updated MainMenu should look:

Key Modifications:

Categories Sorting: Utilizing sorted(by: {$0.key > $1.key}) to ensure your categories are organized correctly.

NavigationLink: Passing the specific consoles by utilizing category.value when navigating to ConsoleMenu.

Step 2: Update ConsoleMenu Structure

Next, you need to modify the ConsoleMenu to accept the list of consoles provided from the main menu.

Here’s the adjusted ConsoleMenu code:

Key Modifications:

Variable Definition: Accepting the consoles directly as a parameter via var con: [ConsoleDetails], allowing you to utilize the relevant console details based on the selected category.

Conclusion

By implementing these adjustments within your SwiftUI project, you’ll enable your application to display menu items that correspond to the selected navigation option seamlessly. This structure not only enhances the user experience but also keeps your code organized and manageable.

Whether you're new to SwiftUI or have some experience, these steps are vital for creating apps that are intuitive and easy to navigate. Continue building and customizing your Nintendo console app, and soon you'll have a polished product worthy of showcasing.

Happy coding!
