BottomSheet

BottomSheet enables use of UISheetPresentationController in SwiftUI with a simple .bottomSheet modifier.

Credit

This repository is based off an initial implementation by @adamfootdev, with significant components remaining unchanged.

Requirements

• iOS 15+
• Xcode 13+

Integration

Swift Package Manager

BottomSheet can be added to your app via Swift Package Manager in Xcode using the following configuration:

dependencies: [
    .package(url: "https://github.com/apptekstudios/BottomSheet.git", from: "1.0")
]

Usage

To get started with BottomSheet, you’ll need to import the framework first:

import BottomSheet

Presenting the Sheet

You can then apply the .bottomSheet modifier to any SwiftUI view, ensuring you attach a binding to the isPresented property – just like the standard .sheet modifier:

.bottomSheet(isPresented: $isPresented) {
    Text("Hello, world!")
}

BottomSheet also supports passing an Optional item to it, displaying the sheet if the item is not nil:

// Some optional value
@State var item: String? = "Showing Sheet"
// In your view body
.bottomSheet(item: $item) { item in
    Text("\(item)")
}

Customizing the Sheet

BottomSheet can be customized in the same way a UISheetPresentationController can be customized in UIKit. This is done by specifying additional properties in the modifier:

.bottomSheet(
    isPresented: $isPresented,
    config: .build {
        $0.detents = [.medium(), .large()],
        $0.prefersEdgeAttachedInCompactHeight = true
    },
    onDismiss: { print("Dismissed") }
) {
    Text("Hello, world!")
}
