[ZoebHusainSheikh]

Hi, I am facing issue in my project, app got crashed because didCaptureCode delegate gets called multiple times

Small workaround to fix issue:

var vcPushed = false

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        
        vcPushed = false
        if (barcodeScanner.isCapturing == false) {
            barcodeScanner.startCapturing()
        }
    }
    
    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        
        if barcodeScanner.isCapturing {
            barcodeScanner.stopCapturing()
        }
    }

func quickScanner(_ scanner: QuickScanner, didCaptureCode code: String, type: CodeType) {
        DispatchQueue.main.async {
            
            if !self.vcPushed {
                self.vcPushed = true
                
                print("Barcode: " + code)
                self.productCode = code
                
                //Do further process
                AudioServicesPlaySystemSound(SystemSoundID(kSystemSoundID_Vibrate))
                scanner.stopCapturing()
                
                self.performSegue(withIdentifier: "ProductDetailsViewController", sender: self)
            }
        }
    }

Hope it helps someone.
