在SwiftUI的不同视图中访问私有变量？

struct MyView: View {
    @State private var myVariable: String = "Initial value"
    
    var body: some View {
        VStack {
            Text(myVariable)
            Button(action: {
                self.myVariable = "New value"
            }) {
                Text("Change Value")
            }
        }
    }
}

@State private var myVariable: String = "Initial value"

var body: some View {
    VStack {
        Text(myVariable)
        // other view components
    }
}

Button(action: {
    self.myVariable = "New value"
}) {
    Text("Change Value")
}
