1. Choose the appropriate navigation pattern (NavigationStack, NavigationSplitView, sheet, TabView) based on the app's requirements.
2. Define routes as a `Hashable` enum for type-safe navigation.
3. Implement the navigation structure using SwiftUI components like `NavigationLink`, `NavigationDestination`, and `TabView`.
4. Handle programmatic navigation using `NavigationPath` for `NavigationStack`.
5. Implement deep linking using `.onOpenURL` and `.onContinueUserActivity`.
6. Test the navigation flow on different devices and screen sizes.
7. Address any common mistakes and optimize for performance.
