Same bug here.
UITabBarItem.Appearance.SetTitleTextAttributes seems bugged too.

yes the UISwitch is now broke in latest xamarin forms update the switch color is changed to default color in iOS (green) how can we customize now to other color

[markjackmilian]

@vyasaraj999 you can use the “oncolor ” property in xamarin forms switch

[philmoz]

Is this ever going to get fixed or do I now have to manually add another property to every switch?

Instead of having one theme setting applied to all switches I now have to add a property to them all (and hope I don't miss one).

What happened to not breaking existing functionality?

[markjackmilian]

@philmoz you can easily create a style in your app.xaml to add color on all your switch:

<Style TargetType="Switch"> <Setter Property="OnColor" Value="yourcolor"/> </Style>

Should be fixed on 3.3.0 as pr #3819 was merged alread
