程式碼定位、追蹤與修改操作筆記
This article provides a comprehensive guide on how to locate, trace, and modify code without the use of AI. It outlines a workflow for identifying function definitions, finding references, and ensuring safe modifications. The guide emphasizes the importance of using the right tools and methods at each stage of the process.
- ▪The article details a workflow for code modification that does not rely on AI tools.
- ▪It highlights the importance of first narrowing down the search with quick tools before using more precise ones.
- ▪The guide includes specific commands and tools for locating function definitions and references in Swift projects.
