Designing iOS apps begins with clarity about the target users, the app’s purpose, and the key problem to solve in the initial release. A thorough discovery phase defines the MVP scope, selects an appropriate architecture, and avoids features that sound appealing on paper but don’t enhance actual usage.

After the foundation is established, attention turns to how the interface behaves, along with performance and reliability across different iPhone models and iOS versions. Uniform navigation patterns, robust state management, and well-planned integrations (payments, authentication, analytics, and backend APIs) help keep the product maintainable and scalable after it hits the App Store.
