How to Use

To use the Partial Sheet just attach the new modifier:

YourView
.partialSheet(
    presented: Binding<Bool>, 
    backgroundColor: Color = Color.white, 
    handlerBarColor: Color = Color.gray, 
    enableCover: Bool = true, 
    coverColor: Color = Color.black.opacity(0.4), 
    view: @escaping () -> SheetContent) -> some View where SheetContent : View

If you want a starting point copy in your ContentView file the following code:

import SwiftUI
import PartialSheet

struct ContentView: View {

    @State private var modalPresented: Bool = false
    @State private var longer: Bool = false

    var body: some View {
        NavigationView {

            VStack {
                Text("""
				Hi, this is the Partial Sheet modifier.
				It allows you to dispaly a totally custom sheet with a relative height based on his content.
				In this way the sheet will cover the screen only for the space it will need
				""")
                Spacer()
                Button(action: {
                    self.modalPresented = true
                }, label: {
                    Text("Display the Partial Shehet")
                })
                    .padding()
                Spacer()
            }
            .padding()
            .navigationBarTitle("Partial Sheet")
        }
        .partialSheet(presented: $modalPresented) {
            VStack {
                Group {
                    Text("Settings Panel")
                        .font(.subheadline)
                    Toggle(isOn: self.$longer) {
                        Text("Advanced")
                    }
                    .padding()
                }
                .frame(height: 50)
                if self.longer {
                    VStack {
                        Text("More settings here...")
                    }
                    .frame(height: 200)
                }
            }
        }
    }
}
