Unable to get password autofill effect to work

I am developing a Xamarin.Forms app for iOS and Android. So far i only tested on iOS since that is the client priority.

i have followed the guide here to setup the password autofill but it does not seems to work. I follow the guide till the Domain association section since from what i read it does not seems to be needed for my case as my app do not have a registration function in the website or app.

I am assuming the linking of AutofillEffect.cs and the AppleAutofillEffect.cs is not link properly.

Code for AutofillEfect.cs
using System;
using System.Collections.Generic;
using System.Text;
using Xamarin.Forms;

namespace MyProject
{
    public class AutofillEffect : RoutingEffect
    {
        public AutofillContentType Type { get; set; }

        public AutofillEffect() : base("PasswordAutofill." + nameof(AutofillEffect))
        {
        }
    }
}

Code for AppleAutofillEffect.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Xamarin.Forms;
using Xamarin.Forms.Platform.iOS;
using Foundation;
using UIKit;

[assembly: Xamarin.Forms.ResolutionGroupName("PasswordAutofill")]
[assembly: Xamarin.Forms.ExportEffect(typeof(MyProject.iOS.AppleAutofillEffect), "AutofillEffect")]
namespace MyProject.iOS
{
    public class AppleAutofillEffect : PlatformEffect
    {
        protected override void OnAttached()
        {
            var effect = (AutofillEffect)Element.Effects
                .FirstOrDefault(e => e is AutofillEffect);
            if (effect != null
                && UIDevice.CurrentDevice.CheckSystemVersion(11, 0)
                && Control is UITextField textField)
            {
                switch (effect.Type)
                {
                    case AutofillContentType.None:
                        textField.TextContentType = NSString.Empty;
                        break;
                    case AutofillContentType.Username:
                        textField.TextContentType = UITextContentType.Username;
                        break;
                    case AutofillContentType.Password:
                        textField.TextContentType = UITextContentType.Password;
                        break;
                }
            }
        }

        protected override void OnDetached()
        {
            if (UIDevice.CurrentDevice.CheckSystemVersion(11, 0)
                && Control is UITextField textField)
            {
                textField.TextContentType = NSString.Empty;
            }
        }
    }
}
