How do you study and understand a new project?

To learn a new iOS project, I usually start by reviewing the documentation, if available — this helps understand the overall architecture and purpose of the application. Then I examine the project structure in Xcode, paying attention to the main modules and their relationships.

Next, I run the application to see how it works and its main usage scenarios. After that, I study the key classes and patterns used (for example, MVC, MVVM).

If the project is large, it’s helpful to create a map or diagram of components to better navigate. I also don’t hesitate to ask colleagues questions and use code analysis tools to understand dependencies and logic.

This approach helps to quickly immerse oneself in the project and start working effectively.
