Crafting iOS apps begins with clear understanding: the target users, the main function the app should fulfill, and the scenario to address in the initial launch. A thorough discovery phase helps outline the MVP, select an appropriate architecture, and steer away from features that seem impressive on paper but don’t enhance actual use.

After laying the groundwork, attention turns to the app's interface behavior, performance, and reliability across different iPhone models and iOS versions. Uniform navigation schemes, thoughtful state management, and well-planned integrations (payments, auth, analytics, backend APIs) help keep the product maintainable and scalable following the App Store release.
