when I toggle ios emulator appearance to light or dark mode I see only light icon is showing

Start by reproducing the issue with the shown iOS icon configuration on an iOS emulator, toggling between light and dark appearance. Inspect the generated iOS icon assets and how image_path_ios_dark_transparent is consumed; the fix is complete when the light and dark appearances display their corresponding icons.
