Chart not able to work on my iOS simulator and device.

[Choy]

I am using version 19.3.0.56 and it works well in my android device. When it comes to iOS, I am able to view the xaxis and yaxis but not the line when I am binding my item source to my view model.

Things I have done:

1. Install syncfusion chart nuget in all of PCL and native projects.
2. Added Syncfusion.SfChart.XForms.iOS.Renderers.SfChartRenderer.Init(); after forms init

My Sample Code:

            <StackLayout Padding="0,20,10,20" VerticalOptions="FillAndExpand">

                <chart:SfChart VerticalOptions="FillAndExpand" AreaBackgroundColor="#F3F8FF">

                    <chart:SfChart.PrimaryAxis>

                        <chart:NumericalAxis Interval="5" ShowMajorGridLines="False">

                            <chart:NumericalAxis.Title>

                                <chart:ChartAxisTitle FontFamily="RegularPoppins" Text="Age"></chart:ChartAxisTitle>

                            </chart:NumericalAxis.Title>

                        </chart:NumericalAxis>

                    </chart:SfChart.PrimaryAxis>

                    <chart:SfChart.SecondaryAxis>

                        <chart:NumericalAxis Minimum="0" Interval="2" ShowMajorGridLines="False">

                            <chart:NumericalAxis.LabelStyle>

                                <chart:ChartAxisLabelStyle LabelFormat="# kg"/>

                            </chart:NumericalAxis.LabelStyle>

                            <chart:NumericalAxis.Title>

                                <chart:ChartAxisTitle FontFamily="RegularPoppins" Text="Weight (in kg)"></chart:ChartAxisTitle>

                            </chart:NumericalAxis.Title>

                        </chart:NumericalAxis>

                    </chart:SfChart.SecondaryAxis>

                    <chart:FastLineSeries ItemsSource="{Binding WeightChart}" XBindingPath="Age" YBindingPath="Weight" Label="Child">

                </chart:SfChart>

            </StackLayout>

Hi, I have manage to fix the issue, it is because I am using list instead of 

ObservableCollection
