Developing iOS apps begins with clear understanding: the target users, the task the app should accomplish, and the scenario the initial release must address. A solid discovery phase helps define the MVP scope, pick the appropriate architecture, and avoid features that look good on paper but don't improve real use.

After the foundation is in place, attention turns to how the UI behaves, performance, and reliability across iPhone models and iOS versions. Consistent navigation, thoughtful state management, and well-planned integrations (payments, authentication, analytics, backend APIs) make the product easier to maintain and scale after it hits the App Store.
