Version history Pixelnetica™ Document Scanning SDK for Apple iOS

All notable changes to the Document Scanning SDK for iOS are recorded here, so you can see what changed before updating.

[3.0.0]

A full rewrite of the Document Scanning SDK for iOS. If you are upgrading from 2.x, read the migration guide first — the API surface has changed.

Added

  • Swift Package Manager distribution. Add https://github.com/Pixelnetica/DocScanningSDK-iOS as a package dependency; the SDK ships as two binary frameworks: DocScanningSDK (core scanning, image processing, and document export) and DocScanningSDK-UI (ready-made screens).
  • On-device OCR with support for over 100 languages. Recognition runs entirely on the device — no cloud processing — and handles multi-language documents in a single pass, including right-to-left (RTL) scripts. Recognised text exports as plain text or as a searchable PDF.
  • Offline text-orientation detection (OSD). Automatically corrects page orientation from document content, and works on a fresh install with no network download.
  • PDF composing engine with advanced image compression — up to 90% smaller files for colour and greyscale pages and 50% for black-and-white, with selectable compression levels from “Lossless” to “Extreme”. It produces layered (“sandwiched”) PDFs, embedding a searchable text layer above the page image for indexing, search, and copy.
  • Batteries-included UI screens in DocScanningSDK-UI, each adoptable in a single line: a smart document camera with live border detection, automatic capture, and interactive quality guidance (trapezoid-distortion and effective-document-area indicators); an OCR results editor with manual correction; an OCR language picker with search; and a page/border editor.
  • A bundled, browsable API reference and a refreshed documentation set, including a 2.x → 3.x migration guide.
  • Third-party attribution notices bundled with the framework.
  • An Apple privacy manifest (PrivacyInfo.xcprivacy) in each framework, declaring on-device processing with no tracking and no data collection. This lets your app’s App Store submission account for the SDK automatically.
