```

]
```

### Manual Installation

just be sure you have the **copy items if needed** and the **create groups** options checked.

### Do you want to use SwiftQRCodeScanner with SwiftUI?
Please follow this example [QRCodeSwiftUIExample](https://github.com/vinodiOS/QRCodeSwiftUIExample).

## How to use
Import SwiftQRScanner module and confirm to the QRScannerCodeDelegate protocol.

```Swift
import SwiftQRScanner

class ViewController: UIViewController {
}

extension ViewController: QRScannerCodeDelegate {
}
```

Create instance of SwiftQRScanner to scan QR code.
```Swift
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**:
```Swift
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:
```Swift
func qrScanner(_ controller: UIViewController, didScanQRCodeWithResult result: String) {
    print("result:\(result)")
}

func qrScanner(_ controller: UIViewController, didFailWithError error: SwiftQRCodeScanner.QRCodeError) {
    print("error:\(error.localizedDescription)")
}

func qrScannerDidCancel(_ controller: UIViewController) {
    print("SwiftQRScanner did cancel")
}
```

Complete code:
```Swift
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 qrScanner(_ controller: UIViewController, didScanQRCodeWithResult result: String) {
        print("result:\(result)")
    }
    
    func qrScanner(_ controller: UIViewController, didFailWithError error: SwiftQRCodeScanner.QRCodeError) {
        print("error:\(error.localizedDescription)")
    }
    
    func qrScannerDidCancel(_ controller: UIViewController) {
        print("SwiftQRScanner did cancel")
    }
}
```
