AppDelegate in IOS fails when navigating to a page with SfDataGrid on it

Question

i'm having problems with SfDataGrid on iOS that works fine on Android when i try to navigate to a page called "Hovedside" that has a SfDataGrid it goes into Main.cs in the iOS part and fails on UIApplication.Main(args, null, "AppDelegate");

using System;
using System.Collections.Generic;
using System.Linq;

using Foundation;
using UIKit;

namespace PrismUnityApp2.iOS
{
    public class Application
    {
        // This is the main entry point of the application.
        static void Main(string[] args)
        {

            try
            {
                UIApplication.Main(args, null, "AppDelegate");
            }
            catch (Exception e)
            {

                throw;
            }
        }
    }
    }

with this output:

System.NullReferenceException: Object reference not set to an instance of an object

There is nothing in the error list

if i remove the SfDataGrid then it navigates just fine to the page

i have the Required assemblies that syncfusion shows on https://help.syncfusion.com/xamarin/sfdatagrid/getting-started

i feel like im missing something in AppDelegate but can't find out what it may be

using System;
using System.Collections.Generic;
using System.Linq;

using Foundation;
using UIKit;
using Prism.Unity;
using Microsoft.Practices.Unity;
using Syncfusion.SfDataGrid.XForms.iOS;

namespace PrismUnityApp2.iOS
{
    // The UIApplicationDelegate for the application. This class is responsible for launching the 
    // User Interface of the application, as well as listening (and optionally responding) to 
    // application events from iOS.
    [Register("AppDelegate")]
    public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
    {
        //
        // This method is invoked when the application has loaded and is ready to run. In this 
        // method you should instantiate the window, load the UI into it and then make the window
        // visible.
        //
        // You have 17 seconds to return from this method, or iOS will terminate your application.
        //
        public override bool FinishedLaunching(UIApplication app, NSDictionary options)
        {
            ZXing.Net.Mobile.Forms.iOS.Platform.Init();

            global::Xamarin.Forms.Forms.Init();
            SfDataGridRenderer.Init();
            LoadApplication(new App(new iOSInitializer()));
            return base.FinishedLaunching(app, options);
        }
    }

    public class iOSInitializer : IPlatformInitializer
    {
        public void RegisterTypes(IUnityContainer container)
        {

        }
    }

}
