Bottom Sheet

Bottom Sheet component is designed to handle any content, including a scrolling one.

  • ✅ use any content size, and it will adapt
  • ✅ use scrollable content: UICollectionView, UITableView or UIScrollView
  • ✅ dismiss interactively by swipe-down or just tapping on an empty space
  • ✅ build flows inside using BottomSheetNavigationController
    • ✅ supports all system transitions: push and (interactive) pop
    • ✅ transition animated between different content sizes
  • ✅ Customize appearance:
    • pull bar visibility
    • corner radius
    • shadow background color

Installation

Swift Package Manager

To integrate Bottom Sheet into your Xcode project using Swift Package Manager, add it to the dependencies value of your Package.swift:

dependencies: [
    .package(url: "https://github.com/joomcode/BottomSheet", from: "2.0.0")
]

Getting started

This repo contains demo, which can be a great start for understanding Bottom Sheet usage, but here are simple steps to follow:

  1. Create UIViewController to present and set content’s size by preferredContentSize property
  2. (optional) Conform to ScrollableBottomSheetPresentedController if your view controller is list-based
  3. Present by using presentBottomSheet(viewController:configuration:)

If you want to build flows, use BottomSheetNavigationController

presentBottomSheetInsideNavigationController(
    viewController: viewControllerToPresent,
    configuration: .default
)

You can customize appearance passing configuration parameter

presentBottomSheet(
    viewController: viewControllerToPresent,
    configuration: BottomSheetConfiguration(
        cornerRadius: 10,
        pullBarConfiguration: .visible(.init(height: 20)),
        shadowConfiguration: .init(backgroundColor: UIColor.black.withAlphaComponent(0.6))
    )
)
