HalfSheet

A SwiftUI view modifier and helper to present a half-screen modal sheet in your iOS apps.

Features

• Interactive drag-to-dismiss gestures
• Configurable close control (drag bar or close button)
• Prevent interactive dismiss when needed
• Dismiss action available via environment

Installation

Add the following dependency to your Package.swift:

.package(url: "https://github.com/velos/HalfSheet.git", from: "0.1.0"),

Then add "HalfSheet" to your target's dependencies:

targets: [
    .target(
        name: "YourApp",
        dependencies: ["HalfSheet"]
    )
]

Usage

Import the package:

import HalfSheet

Use the .halfSheet view modifier to present content:

struct ContentView: View {
    @State private var isPresented = false

    var body: some View {
        Button("Show Half Sheet") {
            isPresented = true
        }
        .halfSheet(isPresented: $isPresented) {
            Text("Hello from half sheet!")
                .padding()
        }
    }
}

To use item-based presentation:

struct Item: Identifiable, Equatable {
    let id = UUID()
    let title: String
}

struct ContentView: View {
    @State private var selectedItem: Item?

    var body: some View {
        List(items) { item in
            Button(item.title) {
                selectedItem = item
            }
        }
        .halfSheet(item: $selectedItem) { item in
            Text(item.title)
                .padding()
        }
    }
}

public extension View {
    func halfSheet(isPresented: Binding<Bool>,
                   closeType: CloseType = .dragBar,
