Unable to convert CIImage to UIImage in Swift 3.0

Question

I am making image form QR Code by using following code:

  func createQRFromString(str: String) -> CIImage? {
        let stringData = str.dat         


        

Answer 1

func convert(cmage:CIImage) -> UIImage
{       
    let context:CIContext = CIContext.init(options: nil)
    let cgImage:CGImage = context.createCGImage(cmage, from: cmage.extent)!        
    let image:UIImage = UIImage.init(cgImage: cgImage)        
    return image
}

Use this function to convert CIImage to UIImage . It works .
