SfChart Legend Issue with Xamarin.Forms and MacOS Catalina

[Benoit Lauzon]

Hello,

I use SfChart in an application build with Xamarin-Forms which runs on MacOS.  I tried the app on Catalina and the SfChart won't display if the Legend is shown.  I fI comment out Legend code, everything runs fine.

Code for legend looks like this:

                             chart.Legend = new ChartLegend();
            chart.Legend.DockPosition = LegendPlacement.Right;
            chart.Legend.ItemMargin = new Thickness(0, 4, LegendRightMargin, 4);
            chart.Legend.LabelStyle.FontFamily = "Roboto-Regular";
            chart.Legend.LabelStyle.FontSize = LegendFontSize;

Here is the error message:

NSInternalInconsistencyException: could not dequeue an item of kind: NSCollectionElementKindItem with identifier LegendCell - must register a nib or a class for the            identifier, or name a nib or class to match the identifier

Do someone hava an idea what the issue is and how to fix it ?

Thanks,

Benoit
