I set the property displayImage ("image:" label) of the INObject like the below.
Card(identifier: card.cardName,
display: card.cardName,
subtitle: card.cardNumber,
image: INImage(url: URL(string: card.cardImageUrl)!))
The selection list is displayed correctly.
However the selected card image is not displayed in the Edit Widget screen.
Edit Widget screen - https://github.com/hackenbacker/FictionalCard/blob/main/Assets/SS18.56.32.png
I put the codes on my GitHub.

Any help would be appreciated.
