Developing iOS applications begins with clear intent: identifying the users, the core function of the app, and the main scenario to tackle in the initial release. A robust discovery phase helps define the MVP scope, pick the right architecture, and skip features that seem impressive on paper but don't improve actual usage.

Once the foundation is in place, the focus shifts to interface behavior, performance, and stability across iPhone models and iOS versions. Consistent navigation patterns, thoughtful state management, and well-planned integrations (payments, authentication, analytics, backend APIs) make the product easier to maintain and scale after the App Store launch.
