## What it is
A Swift library for iOS that lets developers preview their UIKit app across multiple device sizes, orientations, and Dynamic Type font sizes without launching separate simulators. It was designed to catch layout bugs early but is now deprecated in favor of Xcode Previews.

## Use cases
- preview ios app on all device sizes without simulators
- test dynamic type font sizes in uikit
- check layout in different orientations
- verify size classes for iphone and ipad
- catch layout bugs before app store submission

## When to choose
- maintaining a legacy iOS 10+ UIKit app without Xcode Previews
- needing in-app device and font size switching on older Xcode versions

## When to avoid
- starting a new project - use Xcode Previews instead
- the library is deprecated and will be archived
- using SwiftUI rather than UIKit with Auto Layout

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, testing, accessibility
- domain: mobile-development, accessibility, developer-tools
- platform: -
- tags: uikit, size-classes, dynamic-type, device-preview, xcode-previews-alternative, ios, swift, mobile
