## What it is
PreviewTransition is a Swift UI library providing a simple preview gallery controller with animated transitions for iOS apps. It is developed and maintained by Ramotion and distributed via CocoaPods and Carthage.

## Use cases
- add an animated preview gallery to an iOS app
- implement card-to-detail transition animations in Swift
- build a photo or product gallery UI controller on iOS
- create expandable image preview screens with smooth transitions
- customize a gallery controller with custom card covers and text

## When to choose
- you are building an iOS app in Swift and want a ready-made animated preview gallery
- you want a lightweight, MIT-licensed UI controller you can drop into your project via CocoaPods or Carthage
- you need customizable gallery cards for e-commerce, real estate, or media browsing screens

## When to avoid
- you are targeting SwiftUI (not UIKit) or need modern iOS-only features beyond iOS 9/Xcode 9 era tooling
- you need an actively developed library with recent updates and ongoing support
- your project is not iOS/mobile or uses a language other than Swift
