How to use Scanner View

Add camera usage description to your info.plist

<key>NSCameraUsageDescription</key>
<string>This app needs access to the camera, to be able to read barcodes.</string>

import SwiftUI
import CarBode

struct ContentView: View {
    var body: some View {
        VStack{
        CBScanner(supportBarcode: [.qr, .code128]) //Set type of barcode you want to scan
                    .interval(delay: 5.0) //Event will trigger every 5 seconds
                       .found{
                            //Your..Code..Here
                            print($0)
                      }
        }
    }
}

How to turn torch light on/off

import SwiftUI
import CarBode

@State var torceIsOn = false

struct ContentView: View {
    var body: some View {
        VStack{

        Button(action: {
            self.torceIsOn.toggle()
        }) {
            Text("Toggle Torch Light")
        }
            
        Spacer()
        
        CBScanner(supportBarcode: [.qr, .code128]) //Set type of barcode you want to scan
                    .torchLight(isOn: self.torceIsOn) // Turn torch light on/off
                    .interval(delay: 5.0) //Event will trigger every 5 seconds
                       .found{
                            //Your..Code..Here
                            print($0)
                      }
        }
    }
}

Test on iOS simulator

The iOS simulator doesn't support the camera yet but you can set a mock barcode for iOS simulator.

No need to remove the mock barcode it will only use for iOS simulator.

 CBScanner(supportBarcode: [.qr, .code128])
            .interval(delay: 1.0)
            .found{
                print($0)
            }
            .simulator(mockBarCode: "MOCK BARCODE DATA 1234567890")

How to use barcode generator view

Excample code

import SwiftUI

struct ModalBarcodeGenerator: View {
    @State var dataString = "Hello Carbode"
    @State var barcodeType = CBBarcodeView.BarcodeType.qrCode
    @State var rotate = CBBarcodeView.Orientation.up

    var body: some View {
        var body: some View {
        VStack {
            CBBarcodeView(data: $dataString,
                barcodeType: $barcodeType,
                orientation: $rotate)
                .frame(minWidth: 0, maxWidth: .infinity, minHeight: 400, maxHeight: 400, alignment: .topLeading)
        }
    }
}

Barcode type you can generate

//QR Code
// CBBarcodeView.BarcodeType.qrCode
//Code 128
// CBBarcodeView.BarcodeType.barcode128
//Aztec Code
// CBBarcodeView.BarcodeType.aztecCode
//PDF417
// CBBarcodeView.BarcodeType.PDF417

@State var barcodeType = CBBarcodeView.BarcodeType.qrCode
CBBarcodeView(data: ..... ,
                barcodeType: $barcodeType ,
                orientation: ... )

Rotate your barcode

/*Youcan rotate 4 directions
CBBarcodeView.Orientation.up
CBBarcodeView.Orientation.down
CBBarcodeView.Orientation.left
CBBarcodeView.Orientation.right*/

@State var rotate = CBBarcodeView.Orientation.left
CBBarcodeView(data: ..... ,
                barcodeType: ..... ,
                orientation: $rotate)
