Here’s the demo app again. If you want to code along, you can find this version in the Starter folder for the materials for this lesson. When you build and run, you can see there’s a new tab for text recognition. The text recognition will be similar to the face recognition from the previous lesson. After Vision recognizes the text, the user can cycle through the rectangles to see the bounding box in red and also the recognized string for that line.
