How to present a new view using sheets

SwiftUI’s sheets are used to present new views over existing ones, while still allowing users to drag down to dismiss the new view when they are ready.

To use a sheet, give it something to show (some text, an image, a custom view, etc), add a Boolean that defines whether the detail view should be showing, then attach it to your main view as a modal sheet.

For example, this creates a simple detail view, then presents it from ContentView when a button is tapped:

struct SheetView: View {
    @Environment(\.presentationMode) var presentationMode

    var body: some View {
        Button("Press to dismiss") {
            presentationMode.wrappedValue.dismiss()
        }
        .font(.title)
        .padding()
        .background(Color.black)
    }
}

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

    var body: some View {
        Button("Show Sheet") {
            showingSheet.toggle()
        }
        .sheet(isPresented: $showingSheet) {
            SheetView()
        }
    }
}

Unlike navigation links, sheets don’t require a navigation view to work.

Tip: If you don’t want your sheet to be dismissible by dragging downwards on iOS, use the fullScreenCover() modifier instead.
