如何将macOS SwiftUI视图转换为图像？

import SwiftUI
import AppKit

class SwiftUIImageView: NSView {
    private var hostingView: NSHostingView<AnyView>!

    init(swiftUIView: AnyView) {
        super.init(frame: .zero)
        setupHostingView(swiftUIView: swiftUIView)
    }

    required init?(coder: NSCoder) {
        super.init(coder: coder)
    }

    private func setupHostingView(swiftUIView: AnyView) {
        hostingView = NSHostingView(rootView: swiftUIView)
        hostingView.translatesAutoresizingMaskIntoConstraints = false
        addSubview(hostingView)

        NSLayoutConstraint.activate([
            hostingView.leadingAnchor.constraint(equalTo: leadingAnchor),
            hostingView.trailingAnchor.constraint(equalTo: trailingAnchor),
            hostingView.topAnchor.constraint(equalTo: topAnchor),
            hostingView.bottomAnchor.constraint(equalTo: bottomAnchor)
        ])
    }

    func convertToImage() -> NSImage {
        let image = NSImage(size: bounds.size)
        image.lockFocus()
        draw(bounds)
        image.unlockFocus()
        return image
    }
}

let swiftUIView = AnyView(Text("Hello, SwiftUI!"))
let imageView = SwiftUIImageView(swiftUIView: swiftUIView)
let image = imageView.convertToImage()
