Liquid Glass is not obligatory for all apps. It is a new design element introduced by Apple to create a unified design language across platforms, providing a more fluid and dynamic interaction experience. However, it is best reserved for specific parts of an app, such as the navigation layer that floats above the content. It is not recommended to use Liquid Glass everywhere, as it can make the interface feel cluttered and confusing if overused. Developers are encouraged to use it selectively to enhance their app's design and functionality, particularly for custom controls and views.
For more details on how and when to use Liquid Glass, you can refer to the session Meet Liquid Glass (10:31).
