I've managed to build a user form to get inputs and display them in grids. Right now I have them displayed in a scroll view. I'm avoiding lists so as to get a card like appearance. However, I'm not able to get a delete feature to work as it is done with Lists. I'm new to swift and not sure how to implement delete feature in this grid layout. I would like for users to be able to delete entries. I'm using Core Data, Swift and SwiftUI. Thanks.
