## What it is
Popsicle is a Swift framework for creating and managing value interpolations with built-in UIKit support. It lets developers interpolate properties like UIView attributes over time with configurable easing functions, e.g. driven by scroll offsets.

## Use cases
- interpolate uiview properties based on scroll position
- create custom easing animations in swift
- animate view alpha as user scrolls a table view
- interpolate custom value types like cgpoint or cgsize
- build scroll-driven parallax effects in ios

## When to avoid
- you need a maintained library - the project is explicitly no longer maintained
- you just need standard animations, where UIKit/Core Animation APIs suffice
- you target SwiftUI-first projects
