# qrCodeGenerator()

Generates a quick response (QR) code image.

## Declaration

```swift
class func qrCodeGenerator() -> any CIFilter & CIQRCodeGenerator
```

## Return Value

Return Value The generated image.

## Discussion

Discussion This method generates a QR code as an image. QR codes are a high-density matrix barcode format defined in the ISO/IEC 18004:2006 standard. The QR code generator filter uses the following properties: The following code creates a filter that generates a QR code: func qrCode(inputMessage: String) -> CIImage {     let qrCodeGenerator = CIFilter.qrCodeGenerator()     qrCodeGenerator.message = inputMessage.data(using: .ascii)!     qrCodeGenerator.correctionLevel = "H"     return qrCodeGenerator.outputImage! }
