dependencies: [
.package(url: "https://github.com/vinodiOS/SwiftQRCodeScanner.git", from: "1.1.5")
]
Download the latest version ,then unzip & drag-drop the Classes folder inside your iOS project. You can do that directly within Xcode, just be sure you have the copy items if needed and the create groups options checked.
Please follow this example QRCodeSwiftUIExample.
Import SwiftQRScanner module and confirm to the QRScannerCodeDelegate protocol.
import SwiftQRScanner
class ViewController: UIViewController {
}
extension ViewController: QRScannerCodeDelegate {
}
Create instance of SwiftQRScanner to scan QR code.
let scanner = QRCodeScannerController()
scanner.delegate = self
self.present(scanner, animated: true, completion: nil)
To use more features like camera switch, flash and many other options use QRScannerConfiguration:
var configuration = QRScannerConfiguration()
configuration.cameraImage = UIImage(named: "camera")
configuration.flashOnImage = UIImage(named: "flash-on")
configuration.galleryImage = UIImage(named: "photos")
let scanner = QRCodeScannerController(qrScannerConfiguration: configuration)
scanner.delegate = self
self.present(scanner, animated: true, completion: nil)
And finally implement delegate methods to get result:
func qrScanner(_ controller: UIViewController, scanDidComplete result: String) {
print("result:\(result)")
}
func qrScannerDidFail(_ controller: UIViewController, error: QRCodeError) {
print("error:\(error.localizedDescription)")
}
func qrScannerDidCancel(_ controller: UIViewController) {
print("SwiftQRScanner did cancel")
}
Complete code:
import UIKit
import SwiftQRScanner
class ViewController: UIViewController {
@IBAction func scanQRCode(_ sender: Any) {
//Simple QR Code Scanner
let scanner = QRCodeScannerController()
scanner.delegate = self
self.present(scanner, animated: true, completion: nil)
}
@IBAction func scanQRCodeWithExtraOptions(_ sender: Any) {
//Configuration for QR Code Scanner
var configuration = QRScannerConfiguration()
configuration.cameraImage = UIImage(named: "camera")
configuration.flashOnImage = UIImage(named: "flash-on")
configuration.galleryImage = UIImage(named: "photos")
let scanner = QRCodeScannerController(qrScannerConfiguration: configuration)
scanner.delegate = self
self.present(scanner, animated: true, completion: nil)
}
}
extension ViewController: QRScannerCodeDelegate {
func qrScannerDidFail(_ controller: UIViewController, error: QRCodeError) {
print("error:\(error.localizedDescription)")
}
func qrScanner(_ controller: UIViewController, scanDidComplete result: String) {
print("result:\(result)")
}
func qrScannerDidCancel(_ controller: UIViewController) {
print("SwiftQRScanner did cancel")
}
}
