Creating iOS apps begins with clarity: identifying the audience, the app's purpose, and the primary problem to address in the initial release. A solid discovery phase helps outline the MVP, pick an appropriate architecture, and steer away from flashy features that sound good on paper but don't enhance actual usage.

After the basics are established, attention moves to UI behavior, performance, and reliability across different iPhone models and iOS versions. Uniform navigation schemes, meticulous state handling, and thoughtfully designed integrations (payments, authentication, analytics, backend APIs) simplify maintenance and scalability after the App Store release.
