Send Parameter View Modal to App-Delegate File (Xamarain)

Question

I am a Xamarin developer I implement app switching in my project and it's done for the android version but I don't have an idea how to do it for the IOs version

When I use the open URL function in my view controller it's working

~if(Device.RuntimePlatform == Device.iOS)
   {
      try{
            var param = new NSDictionary();
            UIApplication.SharedApplication.OpenUrl(new NSUrl("URL that want to pass"), param, (completed) =>
                {});
                 }
                 catch (Exception ex)
                   {
                      Console.WriteLine(ex.ToString(), "123456");
                   }
          }
    }~ 

but when the app-center built APK for the android it's failed and getting me an error cause of the UIKit library

So I want to pass the parameter(Deeplink URL) from my view modal to App-Delegate File but I am not to much aware about the xamarin so I am not able to do this

Take a look at Xamarin.Essentials: Launcher.

You can use Launcher class directly in Forms project to open a URI, this is often used when deep linking into another application's custom URI schemes.

Sample

var supportsUri = await Launcher.CanOpenAsync("lyft://");
if (supportsUri) 
   await Launcher.OpenAsync("lyft://ridetype?id=lyft_line");

In iOS 9 and greater, Apple enforces what schemes an application can query for. To specify which schemes you would like to use, you must specify LSApplicationQueriesSchemes in your Info.plist file.

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>lyft</string>  
    <string>fb</string>
</array>
