Starting with clarity is essential when building iOS apps: identifying the target users, the core problem the app must solve, and the scenario the initial release should address. A thorough discovery phase clarifies the MVP scope, guides the choice of architecture, and helps avoid features that look impressive on paper but fail to boost actual usage.

After the foundation is in place, attention turns to how the interface behaves, as well as performance and stability across different iPhone models and iOS versions. Consistent navigation patterns, deliberate state management, and well-planned integrations (payments, authentication, analytics, and backend APIs) simplify maintenance and enable scaling after the App Store debut.
