What is the maximum number of user interface screens that can be implemented in one application?

In iOS, there is no strict limit on the maximum number of screens (View Controllers) that can be implemented in an app. Theoretically, any number can be created, but practical limits are related to performance and user experience.

In practice:

• It is recommended to structure the app so that navigation is simple and understandable.
• Too many screens can complicate maintenance and degrade user experience.
• Device memory and performance constraints, especially if screens contain heavy resources, can impose limits.

Thus, the maximum number of screens is determined by the app architecture and UX requirements, not by iOS technical limits.
