## What it is
A Swift UIKit library for building overlay-based interfaces like the draggable bottom sheets in Apple Maps, Stocks, and Shortcuts. It is lightweight and non-intrusive, letting developers control layout and UI customization while handling overlay translation, notches, and gestures.

## Use cases
- implement a bottom sheet in an iOS app
- replicate the Apple Maps draggable overlay
- build a multi-notch draggable panel with UIKit
- add a bottom sheet that works with scroll views
- create a floating panel with customizable snap points

## When to choose
- you need fine-grained control over overlay motion, notches, and animations
- you must support iOS versions before UISheetPresentationController
- you want a non-intrusive library that doesn't dictate your layout
- you need scroll-view and pan-gesture coordination in a bottom sheet

## When to avoid
- you target iOS 15+ and can use the native UISheetPresentationController
- you need SwiftUI-native sheet implementations
- you want a batteries-included UI component with prebuilt styling

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, animation
- domain: mobile-development, frontend
- platform: -
- tags: bottom-sheet, overlay, uikit, swift, draggable-panel, ios, mobile
