Developing iOS apps begins with clarity: identifying the audience, the core function, and the scenario to address in the initial release. A thorough discovery phase helps outline the MVP, pick the appropriate architecture, and avoid adding features that look good on paper but don't enhance actual usage.

After establishing the foundation, attention turns to UI behavior, performance, and reliability across various iPhone models and iOS versions. Consistent navigation, solid state management, and well-planned integrations (payments, authentication, analytics, backend APIs) ease maintenance and scalability after the App Store release.
