Xamarin IOS Shell Itemtemplate FlyoutIcon FontAwesome

Question

I have an Xamarin Shell App. I pulled the code straight from MSDN for the Shell Itemtemplate and it works fine an Android but on IOS the FlyoutIcon is not appearing. I have a feeling it has to do with the fact that I am using FontAwesome for Icons. However I have yet to run across any documentation explaining why there would be an issue with IOS. The icons work perfectly everywehre else in the app. Below is the code for the shell item

 <!-- ItemTemplate is for ShellItems as displayed in a Flyout-->
<Shell.ItemTemplate>
    <DataTemplate>
        <ContentView BackgroundColor="Transparent">
            <Grid ColumnDefinitions="0.2*,0.8*" Margin="10">
                <Image Source="{Binding FlyoutIcon}" 
                   Margin="5"
                   HeightRequest="20" />

                <Label Grid.Column="1"
                   Text="{Binding Title}" 
                   TextColor="LightSlateGray"
                   FontAttributes="Bold"
                   VerticalTextAlignment="Center" />
            </Grid>
        </ContentView>
    </DataTemplate>
</Shell.ItemTemplate>
