Ios 使用SwiftUI显示多个覆盖图

我正在尝试使用SwiftUI显示多张工作表

Overlay.swift

为iOS 13编译此代码的效果与预期一样。另一方面，对于iOS 14，showSheetX（）会打开一个视图为空的工作表。卸下工作表并再次打开它将显示OverlayView_ButtonX。调试表明，当首次调用showSheetX（）时，viewX_visible为false。 这是iOS本身的错误还是我遗漏了什么

提前谢谢你

我想我找到了解决这个问题的方法：

ContentView.swift

导入快捷界面
var view1_visible:Bool=false/我想我找到了这个问题的解决方案：

ContentView.swift

导入快捷界面
var view1_visible:Bool=false//这是否回答了您的问题？这回答了你的问题吗？
import SwiftUI

struct OverlayWith<Content: View>: View {
    let content: () -> Content
    @Environment(\.presentationMode) private var presentationMode
    
    var body: some View {
        VStack{
            Button(action: {
               self.presentationMode.wrappedValue.dismiss()
            }) {
                Image(systemName: "chevron.compact.down")
                    .resizable()
                    .frame(width: 40, height: 15)
                    .accentColor(Color.gray)
                    .padding()
            }
