UIImage is in UIKit, please make sure using UIKit; has been added.

NativeHandle

The NSObject.Handle and INativeObject.Handle properties have changed type from System.IntPtr to a ObjCRuntime.NativeHandle struct. Please make sure using ObjCRuntime; has been added. See NSObject.Handle type change.

CGSize

Please add using CoreGraphics;

Export Verify Static

It's not clear why the key words cannot be added. From the screenshot, it's a partial interface, if your OC code is a Protocol, it can be a partial class or a public interface. If it's a static method, it should be [Static, Export ("method name")].

For further investigate, could you share the .h file of your OC library and the ApiDefinition and StructsAndEnums.cswith me ?

Do you mean calling the UIKIT APIs in your binding project? Or just reference it? I know you have apiDefinition and StructsAndEnums.cs via Sharpie. But you have some errors in the two classes, right? And what you want is to normalize the API definitions, is it? I‘m confused about what the main issues you have.

Create a Static Library (You have a .a library)

Create a Xamarin.iOS Binding Project (you have created the API definitions, right?). (This step please refer to Xamarin.iOS binding project migration - .NET MAUI | Microsoft Learn)

Normalize the API Definitions - Objective Sharpie does a great job of helping us, but it can't do everything. We'll discuss some changes that we need to make to the API definitions before they can be used.

Use the Binding Library - Finally, we'll create a Xamarin.iOS application to show how to use our newly created binding project.
