Starting with clarity is essential when building iOS apps: identifying who the users are, what problem the app should solve, and which scenario must be addressed in the initial release. A thorough discovery phase helps define the MVP scope, select the appropriate architecture, and avoid features that seem impressive on paper but fail to improve actual usage.

After the foundation is in place, attention shifts to how the interface behaves, performance, and stability across various iPhone models and iOS versions. Consistent navigation patterns, careful state management, and well-planned integrations (payments, authentication, analytics, backend APIs) keep the product easier to maintain and scale following the App Store launch.
