![]() ![]() If let outputImage = filter.outputImage?. Let transform = CGAffineTransform(scaleX: 2, y: 2) The code that I found in the mean time was compiling but didn't work, it was a SO example using the "CIFalseColor" filter: var qrImage = UIImage(systemName: "xmark.circle") ?

Let blackImage = context.createCGImage(blackCIImage, from: blackCIImage.extent).map(UIImage.init)! Let whiteCIImage = maskFilter.outputImage! Let blackCIImage = maskFilter.outputImage! Select your brand color and add a logo to make a distinctive QR code that is recognizable from far away. create a version of the code with black foreground. MaskFilter.maskImage = qrCode.applyingFilter("CIColorInvert") Let maskFilter = CIFilter.blendWithMask() and the background becomes black, because white = let color through, black = transparent. Note that we need to invert the code for that, so the actual code becomes white Use the QR code as a mask for blending with a color. So you can, for example, create a black and a white version and use the register(.) method of UIImage to "bundle" them both into one dynamic image: let qrCode = filter.outputImage!.transformed(by: transform) You can use the QR code as a mask and blend it with a solid color to effectively colorize it.
