Import Configuration Feature (v1.2.0)

🎯 Overview

Implements Issue #8: Import existing JSON and Plist configuration files into the app.

This PR adds comprehensive import functionality with two distinct methods optimized for different use cases:

• JSON Import via Copy/Paste (⌘I) - Quick and easy for testing and snippets
• Plist Import via File Selection (⌘⇧I) - Full file support including Intune fragments

✨ Features

JSON Import (Copy/Paste)

• New ImportJSONView with TextEditor dialog
• Keyboard shortcut: ⌘I
• Paste JSON directly from clipboard
• Perfect for quick imports, testing, and sharing snippets
• Immediate validation and error feedback

Plist Import (File Selection)

• NSOpenPanel for file selection
• Keyboard shortcut: ⌘⇧I
• Supports both formats:
  • Full Plist files (with XML headers)
  • Plist fragments (Intune export format without XML headers)
• Auto-wraps fragments in proper Plist structure
• Handles both dictionary and direct array formats

General Import Features

• ✅ Replace all existing favorites on import
• ✅ Preserve folder hierarchies (children arrays)
• ✅ Extract and update toplevel name
• ✅ Automatic format detection
• ✅ Comprehensive error handling with user-friendly messages
• ✅ OSLog integration for debugging

🔧 Technical Implementation

New Files

• ImportService.swift - NSOpenPanel file selection service
• FormatParser.swift - JSON/Plist parsing with fragment support
• ImportJSONView.swift - SwiftUI dialog for JSON paste
• MockImportService.swift - Test mock for unit testing

Modified Files

• AppError.swift - 3 new error types (fileReadFailed, importInvalidFormat, importUnsupportedFormat)
• FavoritesViewModel.swift - Import logic with two entry points
• ContentView.swift - Two import buttons in toolbar with shortcuts

Architecture

• Service Layer - Clean separation of concerns
• Dependency Injection - Testable design
• MVVM Compliant - No UI code in ViewModel
• Swift 6 Concurrency - async/await throughout
• HIG Compliant - Toolbar buttons with keyboard shortcuts

🧪 Testing

Manual Testing Completed

• ✅ JSON copy/paste import
• ✅ Plist file import (full format)
• ✅ Plist fragment import (Intune exports)

• ✅ Keyboard shortcuts (⌘I and ⌘⇧I)

Code Quality

• ✅ Build successful (Debug & Release)

• ✅ OSLog integration for debugging
• ✅ Proper error handling with LocalizedError

📝 Documentation

🎨 UI/UX

Import JSON Dialog

• Clean, modern design with Liquid-Glass styling
• TextEditor with monospaced font for code
• Fixed height (250pt) for optimal button visibility
• Cancel (Esc) and Import (Enter) keyboard shortcuts
