## What it is
A Swift demo app implementing natural gestures and animations from Apple's WWDC18 talk 'Designing Fluid Interfaces', with runnable examples like rubberbanding, spring animations, and the iPhone X flashlight button. It bridges design theory and code-level implementation for iOS interaction patterns.

## Use cases
- implement rubberbanding scroll effects in iOS
- learn how spring animations work with design-friendly parameters
- recreate the iPhone X flashlight button behavior
- detect when a user's gesture motion has paused
- study fluid gesture-driven interface design from WWDC18

## When to choose
- you're building iOS apps with polished, natural-feeling gestures and animations
- you want reference implementations of specific WWDC18 interaction techniques
- you're learning how Apple designs gesture-based interfaces at the code level

## When to avoid
- you need a production-ready animation library with package manager support
- you're targeting Android, web, or non-Apple platforms
- you need actively maintained code with recent updates

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: animation, ui-components
- domain: mobile-development, web-design, tutorials
- platform: -
- tags: gesture-recognition, spring-animation, wwdc18, swiftui-alternatives, demo-app, interaction-design, ios, swift, mobile
