## What it is
Interpolate is a Swift framework for value interpolation that powers interactive, gesture-driven animations on iOS and tvOS. It maps gesture progress (e.g. pan or scroll events) to interpolated values applied to UI properties like colors, frames, and transforms.

## Use cases
- animate view properties based on pan gesture progress
- interpolate colors as a user scrolls
- create interactive swipe-to-dismiss animations
- drive animations from long press gestures
- build gesture-driven UI transitions in Swift

## When to choose
- building iOS/tvOS apps with interactive gesture-driven animations
- you want simple value interpolation tied to gesture progress
- you prefer a lightweight Swift library over full animation frameworks

## When to avoid
- you need cross-platform (Android/web) animation support
- your project uses SwiftUI declarative animations instead of UIKit
- you need actively maintained libraries - last release was 2021

## Facets
- artifact type: library
- maturity: maintenance
- function: animation
- domain: mobile-development, graphics
- platform: -
- tags: gesture-driven-animations, interpolation, uikit, cocoapods, ios, swift, mobile
