If you only want to recognize numbers, I would train the NN. This can be done with the included training app (Put "0123456789" into the textfield). Then replace the old SwiftOCRNet file with the newly generated one.

Thank you
And when I try to run in iOS application it getting crash also. Should I change this one? internal var recognizableCharacters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"

Yes. After replacing the SwiftOCRNet file, you also have to change recognizableCharacter to 0123456789.
