description Overview

Extract Constant

This tool identifies literal values (like '3.14159' or 'MAX_RETRIES') used repeatedly throughout the code. It extracts these 'magic numbers' into a dedicated, named constant field or variable. This centralizes configuration, making global changes trivial and preventing inconsistencies across the codebase.

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.
