I have fixex with SegmentedControlRenderer.

public class CustomSegmentedControlRenderer : SegmentedControlRenderer
    {
        protected override void OnElementChanged(ElementChangedEventArgs<RadSegmentedControl> e)
        {
            base.OnElementChanged(e);

            this.SetSelectedSegmentedColor(this.Element.SelectedSegmentBackgroundColor);
        }

        protected override void OnElementPropertyChanged(object sender, PropertyChangedEventArgs e)
        {
            base.OnElementPropertyChanged(sender, e);

            if (e.PropertyName.Equals(RadSegmentedControl.SelectedSegmentBackgroundColorProperty.PropertyName))
                this.SetSelectedSegmentedColor(this.Element.SelectedSegmentTextColor);
        }

        private void SetSelectedSegmentedColor(Color xColor)
        {
            if (UIDevice.CurrentDevice.CheckSystemVersion(13, 0))
            {
                if (this.Control is UISegmentedControl uISegmented && xColor.ToUIColor() is UIColor color)
                {
                    uISegmented.SelectedSegmentTintColor = color;
                }
            }
        }
    }

Has Telerik indicated if this is going to be fixed and if so when?

I was looking at using the segmented control to replace something else I'm using and I see the problem you describe in iOS 13.

Thanks

In ios 12 or minor working ok. In ios 13 not show (alwais white).
