## What it is
LookinServer is the iOS-side framework that pairs with the free Lookin macOS app to inspect and modify views in a running iOS app, similar to Xcode's UI Inspector or Reveal. It integrates via CocoaPods or Swift Package Manager and should only be included in Debug builds.

## Use cases
- inspect iOS app view hierarchy from a Mac
- modify iOS UI views at runtime
- debug iOS layout issues without rebuilding
- free alternative to Reveal for iOS UI debugging
- display custom member variables of iOS views while debugging

## When to choose
- you need a free Reveal-like view debugger for iOS
- your team builds iOS apps in Swift or Objective-C and wants runtime UI inspection

## When to avoid
- you need a debugger in Release/App Store builds
- you develop for platforms other than iOS

## Facets
- artifact type: library
- maturity: active
- function: developer-tools, gui, testing
- domain: mobile-development, developer-tools
- platform: cpp
