DocumentScanner (ScanUp)

A powerful, privacy-first, and local-first iOS application for document scanning and management. Built natively using SwiftUI and SwiftData.

✨ Features

• Local-First & Blazing Fast: Engineered with SwiftData for highly optimized offline document filtering and sorting, ensuring zero UI lag even with large libraries.
• Biometric Security: Built-in global application privacy lock leveraging Face ID / Touch ID (LocalAuthentication).
• Modern SwiftUI Interface: Premium design omitting heavy 3D effects for a buttery-smooth aesthetic. Features intuitive namespace-based "Morphing Pill" indicators and premium fluid transitions.
• Advanced Document Organization: Organize scans with folders, tags, and intelligent search capabilities.
• System Customization: First-class support for dynamically switching between Light (.light), Dark (.dark), and System themes directly within the app settings.

🛠 Technologies Used

• Swift & SwiftUI: Completely declarative UI written in Modern Swift.
• SwiftData: Powers persistent local caching, model containers, and background data operations.
• LocalAuthentication: Tight hardware-secured document protection.
• VisionKit (VNDocumentCameraViewController): Native document scanning flow.

🚀 Getting Started

Prerequisites

• iOS 18.0+
• Xcode 16.0+ or newer
• An active Apple Developer Account

Installation & Setup

1. Clone the repository:

   git clone https://github.com/your-username/DocumentScanner.git
   cd DocumentScanner

2. Open the project in Xcode: Double-click the DocumentScanner.xcodeproj file.

3. Configure Capabilities & Signing:

   • Go to your Project Target -> Signing & Capabilities.
   • Change the Bundle Identifier and set your Team to your developer account.

4. Build and Run:

   • Select your target device. (Note: A physical device is recommended to effectively test document camera functionality and Face ID).
   • Hit Cmd + R to deploy.

🏗 Architecture Highlights

• Offloaded Heavy Lifting: Filtering, sorting, and tag logic are handled within SwiftData's database engine in tandem with memoization techniques, decoupling expensive operations from the main UI thread.
• State-Driven Routing: Global app state dictates smooth security overlays without requiring heavy navigational wrappers.
