## What it is
SwiftGen is a command-line code generator that produces type-safe Swift constants for project resources like asset catalogs, storyboards, fonts, colors, and localized strings. It uses customizable Stencil templates and helps eliminate String-based APIs and runtime crashes from typos.

## Use cases
- generate type-safe constants for iOS asset catalogs
- avoid typos in localized strings lookups
- generate Swift code for storyboards and XIBs
- make UIColor and UIFont usage compiler-checked
- customize code generation with Stencil templates
- integrate resource code generation into Xcode build phase

## When to choose
- you develop iOS/macOS apps in Swift and want compile-time safety for assets and strings
- your team wants auto-completion instead of String-based resource APIs
- you need customizable code generation via templates

## When to avoid
- your project is not in Swift or not Apple-platform focused
- you only need one-off code generation without template customization
- you prefer runtime dynamic resource access over generated constants
