Platform specific View/Page implementation in .net MAUI

Question

I'm trying to migrate the application implemented using xamarin form and xamarin native.

For example application has four screens out of it two screens(screen1,screen2) implemented using xamarin.form and other two(screen3, screen4) using xamarin native(xamarin.android and xamarin.ios).

Now while migration able to migrate screen1 and screen2(Form) but facing challenges with screen3 and 4(Native).

Can we use the existing screens implemented using storyboard for iOS and xml layout for Android. As of now storyboard initialization using Storyboard.InstantiateViewController(..) as myViewController returns null.

Even getting resource path from bundle returns null

NSBundle.MainBundle.PathForResource(..)

For storyboard not able to set build action to InterfaceDefinition under maui project as this option not available inside Platforms iOS folder.

How can we add new Storyboard/Viewcontroller class to Platform/iOS ?

Any hints/example link for similar project migration will be helpful.

Update:

Recreating both viewcontroller and storyboard and moving to root directory with root namespace worked intialisation. Still facing some tableviewcell unknown key exception

You can check this doc. It tells Invoke platform code in details. — Jianwei Sun - MSFT

@Saamer Not looking for native view implementation in Form. Native views which are already implemented using storyboard need to migrate to MAUI. — Suchith

Copy the code in the file named "LaunchScreen.storyboard" in the xamarin.ios project. Then create a xml file named "LaunchScreen.storyboard" in Platform\ios folder in the .net MAUI project, and Paste the code you copied into it.
