After learning how to use the new Icon Composer to create an icon for an Xcode-created app that looks different in light and dark modes, I tried to copy the newly created icon into an AppleScript applet. This doesn’t work: the information on dark and light modes are stored in an Assets.car file that seems to be unusable in an AppleScript applet.
Has anyone found a way to use Tahoe-compatible icons in an AppleScript applet? (I’ve figured out to create old-style icons that look like Tahoe-icons, and use those icons in AppleScript apps, but of course they don’t change their appearance in dark mode.)
