Creating iOS apps begins with clarity: who the users are, the problem the app must solve, and the scenario to address in the initial release. A thorough discovery phase helps define the MVP, select the proper architecture, and avoid features that seem impressive on paper but fail to enhance actual usage.

After the foundation is in place, attention turns to user interface behavior, performance, and reliability across different iPhone models and iOS versions. Consistent navigation flows, careful state handling, and well-planned integrations (payments, authentication, analytics, backend APIs) make the product easier to maintain and scale following the App Store launch.
