PCL project reference already added in ios project

AppDelegate.cs(1,1): error: The type or namespace name 'App' could not be found (are you missing a using directive or an assembly reference?)
Failed to debug your app.

AppDelegate.cs

#

`using System;
using System.Collections.Generic;
using System.Linq;
using AsNum.XFControls.iOS;
using ImageCircle.Forms.Plugin.iOS;
using Foundation;
using UIKit;

namespace CivilDefense.iOS
{
[Register ("AppDelegate")]
public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
{

    public override bool FinishedLaunching (UIApplication app, NSDictionary options)
    {
        global::Xamarin.Forms.Forms.Init();
        global::Xamarin.FormsMaps.Init();

        AsNumAssemblyHelper.HoldAssembly();
        ImageCircleRenderer.Init();

        LoadApplication(new App());

        return base.FinishedLaunching(app, options);
    }

}

}`

Hope there is solution
