How to change the FontSize and icons size of .net Maui iOS AppShell TabBar?

I have this AppShell:

    <Shell.Resources>
    <Style x:Key="BaseStyle"
           TargetType="Element">
        <Setter Property="Shell.BackgroundColor"
                Value="{DynamicResource YouviRed}" />
        <Setter Property="Shell.ForegroundColor"
                Value="White" />
        <Setter Property="Shell.TitleColor"
                Value="White" />
        <Setter Property="Shell.DisabledColor"
                Value="#B4FFFFFF" />
        <Setter Property="Shell.UnselectedColor"
                Value="#95FFFFFF" />
        <Setter Property="Shell.NavBarIsVisible" 
                Value="False" />
    </Style>
</Shell.Resources>
<TabBar>
    <ShellContent Title="{ext:Translate Dashboard}" 
                  Style="{StaticResource BaseStyle}"
                  Icon="dashboard.png" 
                  ContentTemplate="{DataTemplate navi:CustomNavigationPage}" 
                  Route="Dashboard"  >
        <dash:DashboardView/>
    </ShellContent>
    <ShellContent Title="{ext:Translate Rooms}" 
                  Style="{StaticResource BaseStyle}"
                  Icon="rooms.png" 
                  ContentTemplate="{DataTemplate navi:CustomNavigationPage}" 
                  Route="Rooms" >
        <rooms:RoomsView/>
    </ShellContent>
    <ShellContent  Title="{ext:Translate Settings}"
                   Style="{StaticResource BaseStyle}"
                   Icon="settings.png" 
                   ContentTemplate="{DataTemplate navi:CustomNavigationPage}" 
                   Route="Settings"  >
        <sett:SettingsView />
    </ShellContent>
</TabBar>

The Titles fontSize of the iOS TabBar are to small and the icons are to big, I don't know how to change this. Did I need an specific Handler for this or did anyone knows an better way ? I would be very grateful for any help, thanks in advance.

Set the BaseSize of svg file works for me.

You could add the line in csproj file:

<MauiImage Update="Resources\Images\airplane.svg" BaseSize="50,50" />

You could control the size by change to BaseSize="30,30" or other value. So the Build action of SVG file is MauiImage.

As far as i know we could not change the font size of shell Tabbar. See this thread: How to change Tab title font for TabBar in .NET MAUI. You could also raise an issue on Github.

Hope it works.
