Creating iOS apps begins with clarity about the audience, the core task the app must perform, and the scenario to address in the initial release. A thorough discovery phase helps define the MVP scope, select an appropriate architecture, and skip features that seem impressive on paper but don't enhance actual use.

After the foundation is established, attention moves to UI behavior, performance, and reliability across iPhone models and iOS versions. Cohesive navigation schemes, prudent state management, and thoughtful integrations (payments, authentication, analytics, backend APIs) help keep the product maintainable and scalable following the App Store release.
