I am currently using BarcodeScanner in a SwiftUI project and haven't had any issues so far.

@CLoutas I am trying to use BarcodeScanner in a SwiftUI project. I currently have it displaying using a wrapper but my delegates (code, error, dismiss) never run. Any advice you can give I would be greatful!

[CLoutas]

@ecamodeo are you using a Coordinator object as your delegates? If not, have a look at this: https://www.hackingwithswift.com/books/ios-swiftui/using-coordinators-to-manage-swiftui-view-controllers

@CLoutas I appreciate the time and apologize as I am kind of new to this whole thing but here is what I have for my Coordinator.
class Coordinator: NSObject, BarcodeScannerCodeDelegate, BarcodeScannerErrorDelegate, BarcodeScannerDismissalDelegate {`

func scanner(_ controller: BarcodeScannerViewController, didReceiveError error: Error) {
  print(error)
}

private func makeBarcodeScannerViewController() -> BarcodeScannerViewController {
  let viewController = BarcodeScannerViewController()
  viewController.codeDelegate = self
  viewController.errorDelegate = self
  viewController.dismissalDelegate = self
  return viewController
}

func scanner(_ controller: BarcodeScannerViewController, didCaptureCode code: String, type: String) {
  

    DispatchQueue.main.asyncAfter(deadline: .now() + 2.0) {
        print("Barcode Data: \(code)")
        controller.dismiss(animated: true, completion: nil)
    }
}

func scannerDidDismiss(_ controller: BarcodeScannerViewController) {
  print("Dismissed!")
  controller.dismiss(animated: true, completion: nil)
}

}
`

I'm having two objects, first the actual view (not full code, but should have everything you need):

struct ScannerView: UIViewControllerRepresentable {

func makeCoordinator() -> ScannerViewCoordinator {
    ScannerViewCoordinator(self)
}

func makeUIViewController(context: UIViewControllerRepresentableContext<ScannerView>) -> BarcodeScannerViewController {
    return createAndConfigureScanner(context: context)
}

func updateUIViewController(_ uiViewController: BarcodeScannerViewController, context: UIViewControllerRepresentableContext<ScannerView>) {
        uiViewController.reset(animated: false)
  }

 private func createAndConfigureScanner(context: UIViewControllerRepresentableContext<ScannerView>) -> BarcodeScannerViewController {
    let barcodeVC = BarcodeScannerViewController()
    barcodeVC.codeDelegate = context.coordinator
    barcodeVC.errorDelegate = context.coordinator
    
    return barcodeVC
}

And here is my coordinator (again, not full code):

class ScannerViewCoordinator: BarcodeScannerCodeDelegate, BarcodeScannerErrorDelegate {

private var scannerView: ScannerView

init(_ scannerView: ScannerView) {
    self.scannerView = scannerView
}

func scanner(_ controller: BarcodeScannerViewController, didCaptureCode code: String, type: String) {
    guard let scanItem = ScanParser().parse(content: code) else {
        controller.reset(animated: true)
        return
    }
    
    // Update the view with the scan result.
    self.scannerView.scanResult = scanItem
}

func scanner(_ controller: BarcodeScannerViewController, didReceiveError error: Error) {
    self.scannerView.scanFailed = true
}

}

Let me know if this helps!
