Developing iOS applications starts with clear understanding of who will use them, the core job the app should perform, and which scenario must be addressed in the initial release. A thorough discovery phase helps define the MVP scope, pick the appropriate architecture, and avoid features that look good on paper but don't improve real usage.

After the foundation is in place, the emphasis moves to how the interface behaves, its performance, and stability across different iPhone models and iOS versions. Consistent navigation patterns, careful state management, and well-planned integrations (payments, auth, analytics, backend APIs) simplify maintenance and enable scaling after the App Store launch.
