Developing iOS applications begins with clarity: identifying the target users, the core function the app must provide, and the specific scenario to be addressed in the initial release. A strong discovery phase helps define the MVP boundaries, select an appropriate architecture, and avoid features that look good on paper but don't enhance actual usage.

After the foundation is in place, attention turns to how the UI behaves, performance, and reliability across different iPhone models and iOS versions. Uniform navigation schemes, robust state management, and thoughtful integrations (payments, authentication, analytics, backend APIs) simplify maintenance and facilitate growth after launch in the App Store.
