We have a question with respect to the Live Text feature shown in the Keynote. Is there an API or Framework available for this? Also, if there is a Framework/API available can we leverage it on macOS?
Live Text capability
I think it is using the VNRecognizeTextRequest class from the Vision framework.
You find sample code for an Mac app from the 10041 session here: https://developer.apple.com/documentation/vision/locating_and_displaying_recognized_text
