Quality Assurance (QA) Testing: Throughout development, rigorous testing is conducted to identify and fix bugs, ensure functionality across different iOS devices and versions, and validate the app against the initial requirements. Testing includes unit testing, integration testing, and user acceptance testing (UAT).
