Dear Apple Developer Team, I am writing to request the addition of GS1 DataBar Stacked (both regular and expanded variants) to the barcode symbologies supported by the Vision framework (VNBarcodeSymbology) and VisionKit's DataScannerViewController. Currently, Vision supports several GS1 DataBar formats, such as: VNBarcodeSymbology.gs1DataBar VNBarcodeSymbology.gs1DataBarExpanded VNBarcodeSymbology.gs1DataBarLimited However, GS1 DataBar Stacked is widely used in industries such as retail, pharmaceuticals, and logistics, where space constraints prevent the use of the standard GS1 DataBar format. Many businesses rely on this symbology to encode GTINs and other product data, but Apple's barcode scanning API does not explicitly support it. Why This Feature Matters: Essential for Small Packaging: GS1 DataBar Stacked is commonly used on small product labels where a standard linear barcode does not fit. Widespread Industry Adoption: Many point-of-sale (POS) systems and inventory management tools require this symbology. Improves iOS Adoption for Enterprise Use: Adding support would make Apple’s Vision framework a more viable solution for businesses that currently rely on third-party barcode scanning SDKs. Feature Request: Please add GS1 DataBar Stacked and GS1 DataBar Expanded Stacked to the recognized symbologies in: VNBarcodeSymbology (for Vision framework) DataScannerViewController (for VisionKit) This addition would enhance the versatility of Apple’s barcode scanning tools and reduce the need for third-party libraries. I appreciate your consideration of this request and would be happy to provide more details or test implementations if needed. Thank you for your time and support! Best regards

Hello, I am currently developing an application that requires barcode scanning using Apple’s Vision framework (VNBarcodeSymbology). I noticed that the framework supports several GS1 DataBar symbologies, such as: VNBarcodeSymbology.gs1DataBar VNBarcodeSymbology.gs1DataBarExpanded VNBarcodeSymbology.gs1DataBarLimited However, I could not find any explicit reference to support for GS1 DataBar Stacked (both regular and expanded variants). Could you confirm whether GS1 DataBar Stacked is currently supported in VisionKit's DataScannerViewController or VNBarcodeObservation? If not, are there any plans to include support for this symbology in a future iOS update? This functionality is critical for my use case, as GS1 DataBar Stacked barcodes are widely used in retail, pharmaceuticals, and logistics, where space constraints prevent the use of standard GS1 DataBar formats. I appreciate any clarification on this matter and would be happy to provide additional details if needed.
