What are best practices for using a navigation controller

To effectively use a navigation controller, here are some best practices based on the content from WWDC sessions:

1. Handle Transitions Gracefully:

   • Be prepared for a new transition to start at any time. Don't try to handle being in a transition differently from not being in a transition. For example, always call push regardless of whether a transition is running or not (Enhance your UI animations and transitions).
   • Keep temporary transition state to a minimum. The less state you have, the less likely you are to make other code dependent on transition state, and it's one less thing to clean up. If you do need to keep track of state during a transition, reset it by viewDidAppear or viewDidDisappear (Enhance your UI animations and transitions).

2. Consistency Across Devices:

   • Ensure that navigation elements like tabs are consistent between iPhone and iPad to allow users to navigate easily no matter what device they're using. Avoid adding too many tabs as it can make it harder for users to locate information within your app (Elevate your tab and sidebar experience in iPadOS).

3. Use Delegate Methods:

   • Utilize navigation controller delegate methods such as willShow and didShow to manage state and perform actions at the appropriate times during transitions (Enhance your UI animations and transitions).

4. Adopt New APIs for Enhanced Interactions:

   • Leverage new APIs that simplify building important interactions like customization menus and drag and drop, which can help you accomplish more with less code (Platforms State of the Union).

5. Customization and Personalization:

   • Allow users to customize their navigation experience, such as showing or hiding individual tabs or reordering them. This can make the app more personal and user-friendly (Elevate your tab and sidebar experience in iPadOS).

By following these best practices, you can create a more efficient and user-friendly navigation experience in your app.
