What principle of loading the user interface is used in your application?

In iOS applications, the principle of lazy loading of the user interface is often used. This means that UI elements are loaded and initialized only when they are actually needed by the user, which helps reduce the app's startup time and decrease memory consumption.

For example, view controllers may load heavy resources or data only upon first display, rather than during initialization. Asynchronous data loading with subsequent UI updates is also commonly used to keep the interface responsive.
