Starting to build iOS apps requires clarity: who will use it, what problem the app resolves, and which scenario must be addressed in the initial release. A thorough discovery phase helps define the MVP, select an appropriate architecture, and avoid features that seem impressive on paper but don’t actually enhance usage.

After the foundation is in place, attention turns to UI behavior, performance, and reliability across different iPhone models and iOS versions. Uniform navigation schemes, careful state handling, and well-planned integrations (payments, authentication, analytics, backend APIs) make the product easier to maintain and scale after it hits the App Store.
