Examples

Debug deep link failure
The deep link 'leavn://open/book/Genesis/1' is not navigating to the Bible view. Debug the navigation using the navigation-debugger skill.
Fix tab selection bug
When tapping the 'Bible' tab, it navigates to the 'Journal' tab instead. Use the navigation-debugger to find the issue.

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:

    // 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
