Creating iOS apps begins with clarity: understanding the target users, the core purpose of the app, and the problem the initial release must solve. A solid discovery phase clarifies the MVP scope, selects an appropriate architecture, and avoids features that look good on paper but don't improve actual usage.

After the foundation is in place, attention moves to UI behavior, performance, and consistency across iPhone models and iOS releases. Uniform navigation patterns, robust state management, and well-planned integrations (payments, authentication, analytics, backend APIs) simplify maintenance and enable scaling after the App Store rollout.
