Hello All, I am trying to build a Document scanner where I can manually / automatically detect Documents/receipts/letters from the camera and preview it with the respective crop layer just like VNDocumentCameraViewController does. Can someone guide me in the right direction or if anyone has any examples? I have gone through these WWDC links but didn't get good results.
