Starting with clarity about the audience, the core task the app should accomplish, and the scenario to address in the initial release sets the foundation. A solid discovery phase defines the MVP boundaries, selects the appropriate architecture, and avoids features that appear impressive on paper but don’t enhance real use.

After the base is established, attention moves to UI behavior, performance, and stability across different iPhone models and iOS versions. Uniform navigation flows, reliable state management, and thoughtful integrations (payments, authentication, analytics, backend APIs) simplify maintenance and scalability after the App Store debut.
