Hi,

I face a problem that I could not scan a specific Code 39 barcode with Vision framework. We have multiple barcode in a label and almost all Code 39 can be scanned, but not for specific one.

One more information, regardless the one that is not recognized with Vision can be read by a general barcode scanner.

Have anyone faced similar situation? Is there unique condition to make it hard to scan the barcode when using Vision?(size, intensity, etc)

Regards,

Hello @u-hide

Have you tried specifying all code39 symbologies when creating the BarcodeDetectionProvider? For example:

let barcodeDetection = BarcodeDetectionProvider(symbologies: [.code39, .code39Checksum, .code39FullAscii, .code39FullAsciiChecksum])

Here are all the supported symbologies.

If it still doesn't work, please file a bug report via feedback assistant and include an image of the offending barcode.
