Developing iOS applications starts with clear answers: who will use it, what the app must accomplish, and which scenario needs solving in the initial release. A thorough discovery phase helps define the MVP scope, pick the proper architecture, and avoid flashy features that look good on paper but don't enhance actual use.

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