Navio Implementation Checklist

This document verifies that all components from the comprehensive implementation plan have been effectively implemented.

✅ Completed Implementation

1. Project Setup and Technology Selection

Safari Web Extension Architecture

✅ Manifest v3 configuration
✅ Universal extension (iOS 16+ and macOS 12+)
✅ Content scripts, background script, and popup
✅ Native messaging integration

Xcode Project Configuration

✅ iOS container app with WKWebView
✅ Extension target properly configured
✅ Bundle identifiers configured
✅ Info.plist properly set up

Extension Manifest (manifest.json)

✅ Manifest version 3
✅ Host permissions: <all_urls> for all Google domains
✅ Native messaging permission
✅ Content scripts configured to run at document_end
✅ Icon references for all required sizes (16-512px)
✅ Browser action with popup
✅ Localized extension name and description

2. Content Script Implementation (content.js)

Link Scanning & Interception

✅ Detects Google Search pages (/\.google\./ + /search path)
✅ Detects Google Maps pages (/maps path)
✅ Scans for map links using comprehensive selectors:
- a[href*='//maps.google.']
- a[href*='/maps/place']
- a[href*='/maps/dir']
- a[href*='/maps/search']
- a[href*='/maps?']
✅ Marks processed links to avoid re-processing
✅ Dual interception method:
- Method 1: Rewrites href attribute
- Method 2: Click event interceptor as backup

URL Conversion Logic (googleToAppleMapsURL function)

✅ Simple Place/Address Search
- Extracts q or query parameters
- Converts /maps/place/Name patterns
- Handles URL-encoded names
✅ Directions Links
- Extracts /maps/dir/Origin/Destination patterns
- Handles saddr/origin and daddr/destination parameters
- Omits origin when it's "Current Location"
✅ Coordinates
- Extracts @lat,long,zoom pattern from URLs
- Uses ll parameter in Apple Maps
- Combines coordinates with place names when available
✅ Search URLs
- Handles /maps/search/query pattern
✅ Proper URL encoding with encodeURIComponent()
✅ Error handling with try-catch
✅ Returns null for unparseable URLs

Smart Fallback Mechanism

✅ Detects when user lands on maps.google.com
✅ Waits 500ms for URL to stabilize
✅ Extracts location from Google Maps page URL
✅ Auto-redirects to Apple Maps
✅ Uses native messaging for cleaner UX

DOM Observer

✅ MutationObserver watches for dynamically added content
✅ Processes new map links as Google loads results
✅ Efficient: only processes when nodes are added

Debug Logging

✅ Debug mode toggle (DEBUG constant)
✅ Comprehensive logging throughout the script
✅ Disabled by default for production

3. Background Script (background.js)

✅ Listens for messages from content script
✅ Handles openAppleMaps action
✅ Forwards messages to native app via sendNativeMessage
✅ Error handling with fallback
✅ Async response handling

4. Native Integration (SafariWebExtensionHandler.swift)

✅ Implements NSExtensionRequestHandling
✅ Receives messages from extension
✅ Parses openAppleMaps action
✅ Platform-specific URL opening:
- iOS: UIApplication.shared.open()
- macOS: NSWorkspace.shared.open()
✅ Proper error logging with os_log
✅ Handles both iOS 15+ and earlier API compatibility
✅ Returns success/failure response to extension

- Place in: Navio Extension/Resources/images/
Update Support Email
- Replace support@navio-app.com in ViewController.swift

Test on Physical Devices
- Test on real iPhone (iOS 16+)
- Test on real Mac (macOS 12+)
- Verify all test cases in TESTING.md
Review URL Patterns
