Though Xamarin.Forms TableView is useful, there aren't enough built-in cells. So I always use a ViewCell, but which makes app performance worse.
In order to solve that, I made some custom native cells and a custom TableView which works these cells effectively.
This library named AiForms.SettingsView is available on NuGet.

Nuget

What SettingsView can do.
General
- To set separator color.
- To set selected cell color.
- To scroll to screen top and bottom.
Sections
- To set IsVisible each section.
- To set section a footer.
- To set various options of a header and a footer.
- To use DataTemplate and DataTemplateSelector in a section.
- To reorder items by drag and drop in a section.
Cells
- To set options of all the cells as SettingsView options at once.
- To set indivisual cell options. (indivisual cell options is superior to SettingsView options.)
- To set a cell HintText.
- To use an icon cached in memory at all cells.
- To change corner radius of an icon.
- To use various defined cells.
- To use Xamarin.Forms.ViewCell and the others.
For more information about SettingsView, see ReadMe.md.

Installation
Install-Package AiForms.SettingsView
You need to install this nuget package to PCL/.NETStandard project and each platform project.
For iOS project
To use by iOS, you need to write some code in AppDelegate.cs.
public override bool FinishedLaunching(UIApplication app, NSDictionary options) {
global::Xamarin.Forms.Forms.Init();
AiForms.Renderers.iOS.SettingsViewInit.Init(); //need to write here
LoadApplication(new App(new iOSInitializer()));
return base.FinishedLaunching(app, options);
}

SettingsView properties settings may as well be witten in App.xaml.
For example...
<Application xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:sv="clr-namespace:AiForms.Renderers;assembly=SettingsView"
x:Class="Sample.App">
<Application.Resources>
<ResourceDictionary>
<Color x:Key="AccentColor">#FFBF00</Color>
<Color x:Key="DisabledColor">#E6DAB9</Color>
<Color x:Key="TitleTextColor">#CC9900</Color>
<Color x:Key="PaleBackColorPrimary">#F2EFE6</Color>
<Color x:Key="PaleBackColorSecondary">#F2EDDA</Color>
<Color x:Key="DeepTextColor">#555555</Color>
<Color x:Key="NormalTextColor">#666666</Color>
<Color x:Key="PaleTextColor">#999999</Color>
<x:Double x:Key="BaseFontSize">12</x:Double>
<x:Double x:Key="BaseFontSize+">14</x:Double>
<x:Double x:Key="BaseFontSize++">17</x:Double>
<x:Double x:Key="BaseFontSize-">11</x:Double>
<Style TargetType="sv:SettingsView">
<Setter Property="SeparatorColor" Value="{StaticResource DisabledColor}" />
<Setter Property="BackgroundColor" Value="{StaticResource PaleBackColorPrimary}" />
<Setter Property="HeaderBackgroundColor" Value="{StaticResource PaleBackColorPrimary}" />
<Setter Property="CellBackgroundColor" Value="{StaticResource AppBackground}" />
<Setter Property="CellTitleColor" Value="{StaticResource DeepTextColor}" />
<Setter Property="CellValueTextColor" Value="{StaticResource NormalTextColor}" />
<Setter Property="CellTitleFontSize" Value="{StaticResource BaseFontSize++}" />
<Setter Property="CellValueTextFontSize" Value="{StaticResource BaseFontSize}" />
<Setter Property="CellDescriptionColor" Value="{StaticResource NormalTextColor}" />
<Setter Property="CellDescriptionFontSize" Value="{StaticResource BaseFontSize-}" />
<Setter Property="CellAccentColor" Value="{StaticResource AccentColor}" />
<Setter Property="SelectedColor" Value="#50FFBF00" />
<Setter Property="HeaderTextColor" Value="{StaticResource TitleTextColor}" />
<Setter Property="FooterFontSize" Value="{StaticResource BaseFontSize-}" />
<Setter Property="FooterTextColor" Value="{StaticResource PaleTextColor}" />
</Style>
</ResourceDictionary>
</Application.Resources>
</Application>
Whereby any SettingsView in App will become the same property setttings.
Concluding
I would be grateful if you could use this library.
