description Overview

Extract Field

When several related fields are declared sequentially within a class, this refactoring groups them together and often suggests encapsulating them into a dedicated Value Object (VO) or Data Transfer Object (DTO). This improves the class's cohesion by logically grouping related data members, making the class definition cleaner and more semantic.

Introduce Constant

Constant is a refactoring tool within the JetBrains IDE designed to enhance native applications. It automatically transforms literal numerical values directly in code into named constants. This improves code clarity by replacing "magic numbers" with descriptive names, making maintenance and debugging easier for developers working on projects utilizing Swift or Objective-C.
