    Hello Brendan,

    could you please add support (generating from text field and scanning the code itself) for DataMatrix to the barcode section?

    Thanks in advance!

    The iOS version can scan Data Matrix barcodes because it uses the built-in iOS Vision framework.

    The list of symbologies are here in Apple’s developer documentation:

    https://developer.apple.com/documentation/vision/vnbarcodesymbology?language=objc

    The Mac version uses an open-source project called Bar Code Kit which supports these symbologies:

    https://github.com/Cocoanetics/BarCodeKit

    I’m afraid that Data Matrix is not one of them.

    I looked into the DataMatrix format a little closer and although Apple has a definition for it in their CoreImage Filters, it is not yet supported. I tried implementing the code in a similar way that I implemented the QR Code generator, but I got this error:

    inputBarcodeDescriptor of type CIDataMatrixCodeDescriptor is not yet supported

    So I won’t be able to add it. At least not without investing in some other barcode generator library that might support it.
