如何在SwiftUI中从结构内部的类访问该结构的变量？

struct ContentView: View {
    @State private var count = 0
    
    var body: some View {
        VStack {
            Text("Count: \(count)")
            ChildView(count: $count)
        }
    }
}

struct ChildView: View {
    @Binding var count: Int
    
    var body: some View {
        Button(action: {
            count += 1
        }) {
            Text("Increment")
        }
    }
}
