'调用中缺少参数'hideNew'

我试图切换Bool变量,以便在单击作为按钮的图像时可以取消隐藏视图。我不确定问题是什么,因为据我所知,一切都是对的。再说一遍,我对斯威夫特还很陌生。这是我的代码:

struct ContentView: View {
    @State private var hideNew: Bool = true
    var body: some View {
        ZStack {
            VStack {
                HeaderView() //Error shows here: 'Missing argument parameter 'hideNew' in call'
                    .padding(.bottom, -1.5)
                ScrollView {
                    CountdownView()
                }
                Spacer()
            }
            .frame(width: 600, height: 500)
            if hideNew == false {
                NewDateView()
            }
        }
    }
}

//  The view for the header section
struct HeaderView: View {
    var buttonSize: CGFloat = 25
    @Binding var hideNew: Bool
    var body: some View {
        Spacer()
            .frame(maxHeight: 10)
        HStack {
            Spacer()
            Text("Date Countdown")
                .font(.largeTitle)
                .padding(.trailing, -buttonSize)
            Spacer()
            Image(systemName: "plus")
                .padding(.trailing, 10)
                .frame(width: buttonSize, height: buttonSize)
                .onTapGesture {
                    hideNew.toggle() //This is what I assume the issue is, but I don't actually know what's wrong.
                }
        }
        Spacer()
            .frame(height: 10)
        ExtendedDivider()
            .frame(height: 1.5)
    }
}

任何帮助都将不胜感激。 干杯
