How to Fix SwiftUI List Not Showing Images: A Comprehensive Guide

When developing apps using SwiftUI, one may encounter a frustrating issue: the images that should be displayed in a SwiftUI List seem to be absent. If you’re experiencing this problem, you’re not alone. It’s a common hurdle among developers working with images in SwiftUI. In this article, we'll explore the root of the problem and guide you through the steps needed to solve it effectively.

Understanding the Problem

In the provided code sample, the developer has created a struct for their images, Rune, which consists of a name, image filename, and description. Despite the text being displayed correctly when navigating to the detailed view, users notice that the images are not showing up in the List. This discrepancy can be quite perplexing, especially when the images render correctly when hardcoded, like using Image("Fehu").

Common Indicators of the Issue

Image files not found: The image filenames may not be correctly configured.

Filename extensions: Including the image extensions too often causes problems in SwiftUI.

Incorrect asset catalog organization: Images might not be correctly placed in the Xcode project or asset catalog.

Step-by-Step Solution

1. Check or Adjust Image Filenames

The first thing you should verify is the way the image filenames are configured in your runesArray. In the provided code, the image filenames are assigned with a .png extension. This common mistake can lead to issues in displaying the images.

Correction Needed:
Instead of specifying the filename with an extension like this:

You should drop the .png while declaring the images in your array:

2. Update Your runesArray

Here’s the corrected initialization of the runesArray for clarity:

In this adjustment, we ensure that only the name is passed to runeImage without any file extensions.

3. Revisit Your ContentView and DetailView

After ensuring that your images are correctly named in the runesArray, examine your views which handle displaying the images. In the RuneRow and DetailView structs, make sure you use your images as follows:

This way, the Image constructor will search for an asset with the name you declared in runeImage and will display it accordingly.

Conclusion

Fixing the issue of images not appearing in a SwiftUI List is typically a straightforward fix involving the adjustment of image filenames. By following these steps, you should see your images appear correctly, enhancing the visual appeal of your application.

Be sure to always check your asset catalog and filenames for consistency. This practice will save you time and prevent future headaches. Happy coding!
