How to present a full screen modal view using fullScreenCover()

SwiftUI’s fullScreenCover() modifier gives us a presentation style for times when you want to cover as much of the screen as possible, and in code it works almost identically to regular sheets.

For example, this will present a full screen modal view when the button is pressed:

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

    var body: some View {
        Button("Present!") {
            self.isPresented.toggle()
        }
        .fullScreenCover(isPresented: $isPresented, content: FullScreenModalView.init)
    }
}

Obviously you’ll need to replace FullScreenModalView with your own example view, but something like this ought to be enough to get you started:

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

    var body: some View {
        VStack {
            Text("This is a modal view")
        }
        .frame(maxWidth: .infinity, maxHeight: .infinity)
        .background(Color.red)
        .edgesIgnoringSafeArea(.all)
        .onTapGesture {
            presentationMode.wrappedValue.dismiss()
        }
    }
}
