Release Notes for iOS SDK - 11.x

11.4.1000 (02/05/2026)

Highlights

AI-Powered Barcode Detection and Decoding

  • PDF417 Localization Model – Introduces the PDF417Localization neural network model for improved detection of PDF417 barcodes, especially under challenging conditions.
  • Code39/ITF Decoding Model – Adds the Code39ITFDecoder model for enhanced decoding of Code 39 and ITF barcodes under blurred or low-resolution conditions.
  • Deblur Models for 2D Barcodes – Adds the DataMatrixQRCodeDeblur and PDF417Deblur models provide more effective recovery from motion and focus blur for DataMatrix, QR Code, and PDF417 barcodes.

ECI (Extended Channel Interpretation) Support

  • ECI Information Return – Adds support for retrieving Extended Channel Interpretation (ECI) data from barcodes. The new DSECISegment class, along with eciSegments method in DSBarcodeResultItem class, enable access to character encoding information embedded in barcodes.
  • ECI-Based Text Interpretation – Adds support for interpreting ECI segments during barcode decoding, improving compatibility with international character sets.

Performance Improvements

  • On-Demand Model Loading – Implements lazy loading for AI models, reducing initialization time by loading models only when first needed.
  • Smart Model Selection – Models are now loaded based on configured barcode formats, minimizing memory usage by excluding unused models.
  • Improved Confidence Scoring – Enhances confidence score calculation for results from neural network models, providing more accurate quality indicators.
  • DPM Barcode Optimization – Improves recognition rate for Direct Part Marking (DPM) barcodes commonly used in industrial and manufacturing environments.

11.2.1000 (10/16/2025)

🎉Milestone Release

Version 11.2.1000 introduces a series of AI-driven improvements designed to enhance barcode detection accuracy, processing speed, and configuration flexibility.

This release focuses on practical performance gains for production environments across retail, logistics, and manufacturing workflows.

✨ Key Highlights

AI-Powered Barcode Detection and Decoding

  • New Localization Models – Introduces OneDLocalization and DataMatrixQRCodeLocalization neural network models for improved detection of blurred / low-resolution 1D codes, or partially damaged DataMatrix/QR codes.
  • Specialized Decoders – Adds EAN13Decoder and Code128Decoder models optimized for long-distance and motion-blurred decoding scenarios.
  • Redesigned Deblur Model – The OneDDeblur model now provides more effective recovery from motion and focus blur.
  • Configurable Model Selection – The new ModelNameArray parameter supports flexible model loading and fine-grained control for specific barcode types.

Precision and Processing Control

  • Enhanced Deblur Methods – DM_DEEP_ANALYSIS now includes sub-level control with OneDGeneral, TwoDGeneral, and EAN13Enhanced options.
  • Barcode Count Expectation – The new ExpectedBarcodesCount parameter enables format-specific quantity control and early termination in fixed-count workflows.
  • Improved Region Detection – The new RPM_GRAY_CONSISTENCY mode provides more precise region extraction based on grayscale uniformity and local consistency for document and label processing.

Performance Highlights

Barcode Workflows

  • Up to 26.5% higher read rates under blur conditions with as much as 44% faster processing.
  • Reliable decoding of DataMatrix and QR codes with missing or damaged finder patterns.
  • Extended operational range beyond 75 cm for long-distance barcode scanning.

Developer Notes

  • Backward Compatibility – Fully compatible with existing integrations; no code-level changes required for upgrade.
  • Configuration Flexibility – Expanded parameter set allows comprehensive model configuration for scenario-specific tuning.
  • Production Stability – All new models validated in enterprise environments.

New

  • Added a new method, switchCapturingTemplate, which allows switching templates dynamically during the image processing workflow.
  • Added a new method, clearDLModelBuffers, to release memory by clearing buffered deep learning models.
  • Added a new method, setGlobalIntraOpNumThreads, to configure the global number of threads used for model execution.
  • Added a new button, cameraToggleButton, to the CameraView, allowing users to switch between the front and back cameras. The following APIs are provided for configuring the cameraToggleButton:

11.0.5200 (08/18/2025)

Fixed

  • Fixed an xcframework signature issue.

11.0.5100 (08/05/2025)

Fixed

  • Small fixes and tweaks.

11.0.5000 (07/29/2025)

Changed

  • License Validation Behavior: Instead of stopping execution immediately on an invalid license module, the library now continues processing and returns results from modules with valid licenses. An error is still reported to indicate the license issue.
  • Default Camera Changed: To address short-distance focusing issues on Pro Max iPhones, the default camera has been switched to BackDualWideAuto, enabling automatic switching between the wide and ultra-wide cameras.

Fixed

  • Fixed various minor bugs and improved overall stability.
