## What it is
An Objective-C library by Facebook for fine-tuning iOS app parameters at runtime during development, letting engineers adjust animation timings, colors, thresholds, and feature flags without code changes or a computer. It is archived and no longer actively maintained.

## Use cases
- tune animation timings in an iOS app without recompiling
- adjust colors and physics constants live on device
- temporarily enable or disable features for specific dev devices
- experiment with parameter values during iOS app development
- replace hardcoded constants with adjustable debug values

## When to choose
- you are developing an iOS app in Objective-C and want live parameter tuning
- you want designers to tweak values on-device without rebuilds
- you need lightweight debug-only feature flags with zero release-build overhead

## When to avoid
- you need a maintained library with active support
- your project is in Swift and you prefer modern tooling
- you need production feature flags rather than development-time tuning

## Facets
- artifact type: library
- maturity: maintenance
- function: developer-tools, configuration-management, feature-flags
- domain: mobile-development, developer-tools
- platform: -
- tags: objective-c, ios-development, debugging, parameter-tuning, facebook-archive, ios, mobile
