When an iOS app directs users to the system Settings app to adjust preferences (such as enabling privacy permissions), it should provide a direct shortcut. Using `openSettingsURLString` in `UIApplication` allows developers to programmatically open the app's settings page, minimizing friction for the user.

To design a seamless user experience, iOS apps should minimize the need for configuration settings by prioritizing defaults and querying system information. Key guidelines include:

* **Minimize Settings:** Design the app to work well out-of-the-box, inferring user environment or location from the system rather than requesting manual entry.
* **Prioritize Options:** Place essential, frequently changed options on the main screen, and secondary options on secondary screens. Expose rarely changed options in the system Settings app.
* **Facilitate Access:** Keep configuration direct and convenient within the app when possible. If users must go to the system Settings app, provide a direct shortcut.
