PDF Scanner & Document Manager - Scan, OCR, Sign, Merge PDFs (iOS SwiftUI)
Offline iOS PDF scanner in SwiftUI with OCR, e-signatures, merge/split and lock
Item Description
PDF Scanner is a ready-to-publish iOS app for scanning, organizing and sharing documents. Users scan paper with the camera, clean it up, recognize the text on the device, sign and annotate pages, then share a searchable PDF.
Everything stays on the phone: no account, no server, no ads and no tracking. Built 100% in SwiftUI + SwiftData with Apple frameworks only, with no third-party libraries.
For developers
- SwiftUI, SwiftData, VisionKit, Vision, PDFKit, PencilKit, Core Image and LocalAuthentication.
- Core logic in a separate Swift package (ScanCore) with 33 unit tests: PDF building, merging, splitting, encryption and compression; filters, perspective crop and document detection; OCR, search and passcode hashing.
- Clean structure of models, services, theme and feature folders.
- Debug-only launch arguments open any screen directly, for easy App Store screenshots.
- Builds with no warnings in Xcode 16+.
Requirements
- Xcode 16 or later (tested with Xcode 26.3)
- iOS 17.0 or later
- The document camera needs a real device; the Simulator falls back to photo import
