IconImageSource in SwipeViewItem not working on IOS

[pschubert777]

Description

When using a swipe item in IOS, the IconImageSource does not display the Icon for the SwipeItem in the IOS Simulator. I tested it also with Android and it works there, but not IOS.

To set the images in the Maui Project, I added them to the Resources > Images folder and set the Build Action to MauiImages

IOS - IPhone SE 3rd Gen IOS 16.2

Android - Pixel 5 - API 31

Steps to Reproduce

1. Create a File > New Maui Project
2. Add the check.svg and the delete.svg to the Resource > Images
3. Create an Observable collection in the MainPage.xaml.cs
4. Create a CollectionView and set the ItemSource to the Observable collection in the MainPage.xaml
5. In the DataTemplate, add the following code for the SwipeView
6. Once the code is added, for the SwipeItem in SwipeView.Left set the IconImageSource to delete (for the delete.svg) and in the SwipeView.Right, set the IconImageSource to check (for check.svg)

I solved it by creating a DataTemplateSelector, but the MAUI team should fix it.

public class IssueiOSTemplateSelector : DataTemplateSelector
{
    public DataTemplate AndroidTemplate { get; set; }
    public DataTemplate IoSTemplate { get; set; }

    protected override DataTemplate OnSelectTemplate(object item, BindableObject container)
    {
        if (IsAndroid())
        {
            return AndroidTemplate;
        }

        return IoSTemplate;
    }
    private static bool IsAndroid() => DeviceInfo.Current.Platform == DevicePlatform.Android;
}

Almost 1 year since this issue was reported and I am still using the solution I provided.
