Developing iOS applications starts with clarity about the target users, the core function, and the scenario to address in the initial release. A thorough discovery phase clarifies the MVP scope, guides the choice of architecture, and helps avoid features that look good on paper but don't enhance actual usage.

After the foundation is in place, attention turns to the UI behavior, speed, and reliability across different iPhone models and iOS versions. Uniform navigation patterns, robust state management, and well-planned integrations (payments, authentication, analytics, backend APIs) simplify maintenance and enable scaling after the App Store launch.
