When VoiceOver is enabled, iOS can describe images. If the Image Description option is turned on, this will even create a detailed natural language description of the image.
Is there a way to get this description programmatically? My use case is implementing a thumbnail list, where the image describer only has a tiny image to work with, sometimes with overlaid text, which limits its usefulness. I'd like to give it a slightly larger version of the image and get the description directly so I can set up the accessibilityLabel accordingly.
I just can not find this documented or discussed anywhere, however.
It was confirmed by an Apple engineer that there is no public API for this as of iOS 14.
