Creating iOS apps begins with clarity: identifying the target users, defining the app's purpose, and deciding which problem must be solved in the initial release. A thorough discovery phase helps outline the MVP, pick an appropriate architecture, and avoid features that look good on paper but don’t enhance real usage.

After the foundation is in place, attention moves to how the UI behaves, performance, and reliability 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 simpler to maintain and scale after it appears in the App Store.
