Have to kill the app between scans

[oefterdal]

I have to kill the app between scans, if I Dismiss the sheet and try to perform a new scan it won't scan.

    var body: some View {
        ZStack {
            Rectangle()
                .fill(Color.white)
                .frame(width: 300, height: 100)
                .cornerRadius(20)
                .overlay(
            CodeScannerView(codeTypes: [.ean8, .ean13], showViewfinder: true) { result in
                switch result {
                case .success(let code):
                    self.scannedResult = code.string
                    self.checkResult(result: self.scannedResult!)
                    self.showResult = true
                case .failure(let error):
                    print(error.localizedDescription)
                }
            })
            .sheet(isPresented: $showResult) {
                ResultView(scannedResult: self.$scannedResult, showResult: self.$showResult)
            }
        }
    }
}

struct ResultView: View {
    @Binding var scannedResult: String?
    @Binding var showResult: Bool

    var body: some View {
        VStack {
            Text("Scanned Result")
                .font(.headline)
            if let result = scannedResult {
                Text(result)
                    .font(.body)
            } else {
                Text("No result found")
                    .font(.body)
            }
            Button("Dismiss") {
                self.scannedResult = nil
                self.showResult = false
            }
        }
        .padding()
    }
}
