SwiftUI:如何根据给定的宽度获取HostingController视图/内容maxHeight？

import SwiftUI
import UIKit

struct ContentView: View {
    var body: some View {
        UIViewControllerWrapper()
            .frame(maxWidth: .infinity, maxHeight: .infinity)
    }
}

struct UIViewControllerWrapper: UIViewControllerRepresentable {
    func makeUIViewController(context: Context) -> UIViewController {
        HostingController(rootView: MyView())
    }

    func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
        // 更新视图控制器
    }
}

struct MyView: View {
    var body: some View {
        GeometryReader { geometry in
            Text("Max Height: \(geometry.size.height)")
                .frame(width: geometry.size.width, height: geometry.size.height)
                .background(Color.gray)
        }
    }
}
