## What it is
Jelly is a Swift library for animated, interactive and non-interactive UIViewController transitions and presentations on iOS. It offers a simple yet flexible API for custom view controller animations built on UIKit.

## Use cases

- custom modal presentation animations uikit
- interactive viewcontroller transitions swift
- slide-in or fade view controllers with animation
- custom uipresentationcontroller animations

## When to choose
- you build UIKit-based iOS apps and want polished custom transitions with minimal code
- you need both interactive and non-interactive presentation animations from one library

## When to avoid
- your app is SwiftUI-only and you don't touch UIKit
- you need cross-platform animations outside iOS

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components
- domain: mobile-development, frontend
- platform: -
- tags: uikit, viewcontroller-transitions, uipresentationcontroller, swift, ios, mobile
