Dismiss sheet SwiftUI

Question

I'm trying to implement a dismiss button for my modal sheet as follows:

struct TestView: View {
    @Environment(\.isPresented) var present
    var body: some View {
        Button("return") {
            self.present?.value = false
        }
    }
}

struct DataTest : View {
    @State var showModal: Bool = false

    var modal: some View {
        TestView()
    }
    var body: some View {
        Button("Present") {
            self.showModal = true
        }.sheet(isPresented: $showModal) {
            self.modal
        }
    }
}

But the return button when tapped does nothing. When the modal is displayed the following appears in the console:

[WindowServer] display_timer_callback: unexpected state (now:5fbd2efe5da4 < expected:5fbd2ff58e89)

If you force unwrap present you find that it is nil

How can I dismiss .sheet programmatically?

Use presentationMode from the @Environment.

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

    var body: some View {
        VStack {
            Text("Ohay!")
            Button("Close") {
                self.presentationMode.wrappedValue.dismiss()
            }
        }
    }
}
