How to resolve PhotosUI.PHPickerViewControllerDelegate

Question

I'm using (App Center) to build my Xamarin Forms project, building for Android works fine but whenever I try to build for iOS then I get the below error.

I really don't get the (PhotosUI.PHPickerViewControllerDelegate) issue or how to solve it.

What exactlt do I need to do here.
