Creating iOS apps begins with clarity: identifying who the users are, the primary function the app must perform, and which scenario should be addressed in the initial release. A solid discovery phase helps define the MVP scope, select the appropriate architecture, and avoid features that look good on paper but don't enhance actual usage.

After the foundation is in place, attention moves to UI behavior, performance, and stability across different iPhone models and iOS versions. Uniform navigation patterns, careful state management, and well-planned integrations (payments, authentication, analytics, backend APIs) simplify maintenance and scaling after the App Store release.
