Developing iOS apps begins with clarity: who will use it, what problem the app should solve, and which scenario must be addressed in the initial release. A thorough discovery phase helps define the MVP scope, select the appropriate architecture, and avoid features that seem impressive on paper but don't enhance actual usage.

After the foundation is in place, attention shifts to the 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) make the product easier to maintain and scale after it hits the App Store.
