Navigation Debugger

Fix navigation bugs in Leavn:

1. Check notification handling:

   • Search for notification name in ContentView
   • Verify .onReceive() handlers exist
   • Check AppCoordinator navigation methods

2. Common Leavn patterns:

   Copy// Post navigation
   NotificationCenter.default.post(
       name: .OpenBibleReference,
       userInfo: ["book": "Genesis", "chapter": 1]
   )
   
   // Handle in ContentView
   .onReceive(NotificationCenter.default.publisher(for: .OpenBibleReference)) {
       // Navigate to Bible
   }
   

3. Debug steps:

   • Add AppLog in notification handlers
   • Verify userInfo parsing
   • Check tab selection works
   • Test deep link URLs

Use when: Navigation broken, wrong screen, deep links fail, tab routing issues
