SfCircularGauge not rendering in iOS


I am new to Syncfusion and trying to get a little familiar with you great controls using XAML. I installed Syncfusing using NuGet and working with Xamarin Studio.

Code of my ContentPage looks like this:

<?xml version="1.0" encoding="utf-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
    <Grid Padding="20">
            <RowDefinition Height="200"/>
            <RowDefinition Height="400"/>
        <Label Grid.Row="0" Text="Welcome to Xamarin Forms!" VerticalOptions="Center" HorizontalOptions="Center" />
        <gauge:SfCircularGauge Grid.Row="1"
                StartValue   ="0"
                EndValue     ="100"
                Interval     ="20" >
                 <gauge:TickSettings Length="22" Color="Red">
                 <gauge:TickSettings  Length="12" Color="Green">
                    <gauge:NeedlePointer Value="60" />
      <gauge:Header Text="Speedometer" Position="0.3,0.6" ForegroundColor="Maroon"  />


Unfortunately after running page I only see gray grid row with no scale, header, pointer etc. (I changed background color to see if control is there)

I'll be glad for any help :)

Ok, I figured it out...

Of course the new renderer in AppDelegate was missing.

What do you mean by "the new renderer in AppDelegate was missing"? I have the same problem.

Query: the new renderer in AppDelegate was missing 
For iOS projects, Renderer instance should be created manually to render the controls. So, In AppDelegate file, the following code should be added, 
public override bool FinishedLaunching(UIApplication app, NSDictionary options) 
      new Syncfusion.SfGauge.XForms.iOS.SfGaugeRenderer();    
Please refer our KB article,
