SanFrancisco (.SFUIText,.SFUI-Regular) fonts issue on iOS 13

After updating to iOS 13 my fonts failed.
In my App.xaml I had:
<OnPlatform x:Key="FontFamilyRegular" x:TypeArguments="x:String">
   <On Platform="iOS">.SFUIText</On>
</OnPlatform>
<OnPlatform x:Key="FontFamilyMedium" x:TypeArguments="x:String">
   <On Platform="iOS">.SFUIText-Medium</On>
</OnPlatform>
<OnPlatform x:Key="FontFamilyBold" x:TypeArguments="x:String">
   <On Platform="iOS">.SFUIText-Semibold</On>
</OnPlatform>

It all worked fine until I updated my device to iOS 13.
I debugged iOS project and find out that font names could be changed to:.SFUI-Regular,.SFUI-Semibold - but these do not work neither. Also I tried updating to the latest Xamarin version - no luck.
How can I use these 3 font families in the newest iOS version?

A:

System fonts like this are now longer reference-able with 'dot' /. notation as per:
https://developer.apple.com/videos/play/wwdc2019/227/
Starting with iOS 13, you can utilise the new enum UIFontDescriptor.SystemDesign, using regular, rounded, serif or monospaced.
