Then we return the function so the rest of the function will not run. If there is an error or there are no barcodes recognized, we dismiss the Image Picker View Controller and set the resultView to say “No Barcode Detected”. We define two objects: barcodes and error. We call the detect method of barcodeDetector and run this method on our visionImage.Then we define an image called visionImage which is the same image as the one we picked. We set it to detect all types of barcodes. The first thing we do is define 2 variables: barcodeDetector which is a barcode detecting object of the Firebase Vision service.This will be the basic format for everything else we do for the rest of the tutorial. It may seem like a lot but it’s quite simple. Here’s a quick rundown of everything that went down.
