我试图将SubView SwiftUI 视图添加到UIView。 self.view.addSubview(contentView)
错误：无法将“ContentView”类型的值转换为预期的参数类型“UIView”
请帮我实现这个 UI。

view.backgroundColor = UIColor.lightGray
let contentView = ContentView()
view.addSubview(contentView) // Error: Cannot convert value of type 'ContentView' to expected argument type 'UIView'
}
}
struct ContentView: View {
var body: some View {
Text("Hello world")
}
}

return collectionView
}
func updateUIView(_ uiView: UITableView, context: Context) {

func makeCoordinator() -> Coordinator {
Coordinator(rows: rows)
}

var rows: [String]
init(rows: [String]) {
self.rows = rows
}

/// This will
let cellRegistration = UICollectionView.CellRegistration<UICollectionViewCell, ToDoListItem> { cell, indexPath, item in
cell.contentConfiguration = UIHostingConfiguration {
