I tried the app you suggested. It built a set. I loaded it fresh over the asset folders in my empty project.
I can already see it’s building fine but the appstoreconnect icon isn’t there.
This is the folder it produced.
Still getting the error: "A value for the info.plist key ‘CFBundleIconName’ is missing in the bundle .
But, I have a value for that–I’ve tried lots of values for that key. 1024.png, 1024.jpg, AppIcon, etc.
I tried putting a 1024x1024 image in the well for the store but no joy.
