Description

We have some PNGs that we display via a ViewModel. The property on the ViewModel is an ImageSource

Most of the images live directly under Resources/Images but some are in a subfolder called "signal". All the images have the Build Action of MauiImage

In the ViewModel we load those images into the ImageSource like this:

this.Image = Microsoft.Maui.Controls.ImageSource.FromFile("signal/red_hexagon1.png");

In Android this works fine. In iOS it does not work and we see the following error message in the Output window

[0:] Microsoft.Maui.FileImageSourceService: Warning: Unable to load image file 'Signal/red_hexagon.png'.

System.InvalidOperationException: Unable to load image file.
at Microsoft.Maui.FileImageSourceService.GetImageAsync(IFileImageSource imageSource, Single scale, CancellationToken cancellationToken)

If I move the image into root of "Resources/Images" the image loads fine.

This fails on both the Device (iOS 17.4.1) and Simulator (iPhone 15 iOS 17.4)

It works fine on Android

Steps to Reproduce

Call Microsoft.Maui.Controls.ImageSource.FromFile on iOS with an Image in a sub folder of Resources/Images
