Building iOS apps begins with clarity about the target users, the app's purpose, and the problem the initial release must solve. A solid discovery phase helps define the MVP, select the right architecture, and avoid features that seem impressive on paper but don’t enhance real usage.

After the foundation is in place, attention shifts to how the interface behaves, its performance, and stability across different iPhone models and iOS versions. Uniform navigation patterns, prudent state management, and thoughtful integrations (payments, authentication, analytics, backend APIs) simplify maintenance and scalability after the App Store release.
