Designing iOS apps begins with clarity: who will use it, what task the app should fulfil, 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 look impressive on paper but don’t improve real usage.

Once the foundation is established, attention turns to interface behavior, performance, and stability across iPhone models and iOS versions. Consistent navigation patterns, careful state handling, and well-planned integrations (payments, auth, analytics, backend APIs) simplify maintenance and scaling after the App Store release.
