Unit testing is essential for ensuring code quality, and mastering it can take your iOS development skills to the next level. Xcode provides powerful capabilities for writing advanced unit tests that cover not only simple functions but also more complex scenarios involving asynchronous operations, dependency management, and mock data. This article delves into advanced topics to help you make the most out of Xcode’s unit testing tools.
