Creating iOS apps begins with clarity: identifying target users, defining the app's purpose, and prioritizing the issue to address in the initial release. A thorough discovery phase helps outline the MVP, select the appropriate architecture, and avoid features that look good on paper but don’t enhance actual usage.

After the foundation is in place, attention moves to UI behavior, performance, and reliability across different iPhone models and iOS versions. Uniform navigation, robust state management, and well-planned integrations (payments, authentication, analytics, backend APIs) make the product easier to maintain and scale after launch on the App Store.
