SWIFT4 recognition only numbers

[AndreaIOSDeveloper]

Is it possible to recognize only the numbers within an image?

Yes, it is. Use charWhitelist property.

Yes, I tried it, I have this configuration, I'll attach it below, but it takes literal characters and turns them into numerical ones, you could help me. Thank you

if let tesseract = G8Tesseract(language:"eng+ita") {

        tesseract.delegate = self

        returnImage { (image) in

           // let imageRender = image.g8_grayScale()

            //tesseract.engineMode = .tesseractOnly

            //tesseract.pageSegmentationMode = .singleLine

            tesseract.charWhitelist = "01234567890"

            // tesseract.charBlacklist = "abcdefghilmnopqrstuvzABCDEFGHILMNOPQRSTUVZ"

            //tesseract.maximumRecognitionTime = 120.0

            tesseract.image = image.g8_blackAndWhite()

            tesseract.recognize()

            self.text?.text = tesseract.recognizedText

            return

        }

this configuration doesn't work

Try engineMode as tesseractCubeCombined or cubeOnly.
