Failed to use Tesseract OCR in iOS Swift

I installed Tesseract library using cocoapods (pod 'TesseractOCRiOS', '4.0.0') and imported it in the code without problems, I used the following code to read a text from an image 

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

tesseract.delegate = self
tesseract.charWhitelist = "01234567890"
tesseract.image = image
tesseract.recognize()
print(tesseract.recognizedText)

After running it crashes on the first line, the error is: 

fatal error: unexpectedly found nil while unwrapping an Optional value

Any and all help is appreciated.

Solution

  • Your code seems right. You can try to use if-let condition to check the optional statement. Also have a look, if you aren't already, in this example.

    if let tesseract:G8Tesseract = G8Tesseract(language:"eng+ita") {
    // Continue with you code. 
}
