Learn Test-Driven Development in Swift by understanding how to build reliable and maintainable iOS applications using a test-first approach. This training covers the core TDD cycle: writing tests before code, implementing functionality, and refactoring for improvement. It also explains how to use XCTest for unit testing, define test cases, and validate expected outcomes. You will learn how TDD improves code quality, reduces bugs, and encourages better software design. The course also covers writing modular, testable code and integrating testing into the development workflow. It focuses on building robust, scalable iOS applications through disciplined, test-driven practices.
