This document discusses refactoring code in Xcode using features like renaming methods and variables, moving methods up or down, and marking methods as deprecated. It explains how to access the refactor menu and use features like renaming based on find and replace or using Key-Value Coding getters and setters. It also provides examples of refactoring a method to split it into multiple methods with default parameter values and how to mark methods as deprecated to flag them for removal.
