Creating iOS apps begins with clarity about the target audience, the core function the app must perform, and the scenario the initial release should address. A solid discovery phase helps define the MVP boundaries, select an appropriate architecture, and steer clear of features that seem impressive on paper but don't enhance actual use.

After the basics are in place, attention moves to how the UI behaves, as well as performance and reliability across different iPhone models and iOS updates. Uniform navigation flows, thoughtful state handling, and well-designed integrations (payments, authentication, analytics, backend APIs) help keep the product maintainable and scalable following the App Store release.
