Holding a clear picture at the outset is essential for creating iOS apps: identify the target users, specify the core function, and determine the scenario to address in the initial launch. A solid discovery phase helps delineate the MVP, pick an suitable architecture, and skip features that seem impressive on paper yet don’t enhance actual usage.

After the base is in place, attention moves to UI behavior, performance, and reliability across different iPhone models and iOS releases. Uniform navigation schemes, meticulous state handling, and thoughtfully designed integrations (payments, authentication, analytics, backend APIs) simplify maintenance and scaling after the App Store release.
