Creating iOS apps begins with clear understanding: the target users, the task the app needs to accomplish, and the scenario that must be addressed in the initial version. A solid discovery phase helps outline the MVP, select an appropriate architecture, and steer clear of features that seem impressive in theory but don't enhance actual use.

With the foundation in place, attention moves to UI behavior, performance, and stability across different iPhone models and iOS versions. Uniform navigation flows, meticulous state handling, and thoughtfully planned integrations (payments, authentication, analytics, backend APIs) help keep the product maintainable and scalable after it's released on the App Store.
