Just take the presentationMode from the environment in the destination view and dismiss the wrappedValue from it:

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

    var body: some View {
        Button("Dismiss") {
            self.presentationMode.wrappedValue.dismiss()
        }
    }
}
