Creating iOS apps begins with knowing the audience, the app's purpose, and the scenario to address in the initial release. A solid discovery phase helps establish the MVP boundaries, select an appropriate architecture, and skip features that seem impressive in theory but don't enhance actual usage.

After the core is in place, attention moves to UI behavior, performance, and reliability across different iPhone models and iOS versions. Uniform navigation, thoughtful state management, and well-planned integrations (payments, authentication, analytics, backend APIs) simplify maintenance and scalability post-App Store release.
