Use Vision framework in Xcode to read QR Codes

I need somebody to fix/update the code in a SWIFT app so that it will 1. use ARKit to detect an image and 2. use that as an anchor for a basic scene kit scene AND 3. use the Vision framework to scan a QR Code (VNDetectBarcodesRequest) to 4. update the texture image in the scene.. The SceneKit scene is a single plane with a PNG image for the Diffuse texture which will have a default image assigned to it and will get updated if the Vision Framework detects a QRCode payload value that matches an image file name. Currently i have it coded to create an anchor for the ARKit image and display a scenekit file/scene with the same name, but need to be able to dynamically display different images depending on the QR code. I have attached a screenshot showing an example image that could be used - there would be a larger image used for the ARkit image detection, and a QR code within or beside it - so if you scan the image the scene will pop up right away, but if you zoom in closer to the QR code, it will update the scene image texture. (See additional screenshot showing scene kit scene with Diffuse image texture). I also uploaded existing code from [login to view URL] for reference.
