## What it is
Gemini is a Swift framework for iOS that provides rich scroll-based animations through a custom UICollectionView subclass. It offers multiple animation types (cube, circle rotation, 3D rotation, scale) with customizable properties and a fluent method-chaining API.

## Use cases
- animate collection view cells while scrolling on ios
- create 3d cube or rotation effects in a scroll view
- add scale and fade animations to uicollectionview
- build custom scroll-based animation effects in swift
- make a carousel with circle rotation animation

## When to choose
- you need scroll-linked animations for iOS collection views with minimal setup
- you want prebuilt animation types plus a customizable fluent API in Swift

## When to avoid
- you are not building an iOS app in Swift
- you need animations outside of scroll-based collection view contexts
