## What it is
Fui is a Ruby command-line gem that finds unused Objective-C header (.h) files that are never imported anywhere in a project, indicating classes that can potentially be deleted. It supports options to skip .xib files, ignore local or global imports, exclude paths, and delete unused files with a prompt.

## Use cases
- find unused objective-c classes in my xcode project
- detect header files that are never imported
- clean up dead code in an ios codebase
- delete unused class files safely with a prompt
- ignore pods folder when scanning for unused imports
- find headers only referenced from xib files

## When to choose
- you maintain an Objective-C codebase and want to find deletable classes
- you want a quick CLI scan for headers with no importers
- you need to exclude paths like Pods or ignore xib references

## When to avoid
- you want to find unused #import statements within a single file (use Clang warnings or AppCode)
- your project is primarily Swift
- you need full static analysis rather than import-based heuristics
