I was curious to experiment with the different use cases of Vision's Rectangle Detection framework in iOS and came up with this. A credit card scanner that crops the card and performs a perspective correction. The idea was to stay away from Regular Expressions for parsing the digits of the card. Hence, I created a movable rectangle that allows the user to select the region of interest and extract the text from it!
