如何在Mac而不是iPhone上创建和打印离屏SwiftUI视图？

import SwiftUI

struct OffscreenView: View {
    var body: some View {
        Text("Hello, Offscreen SwiftUI View!")
            .font(.largeTitle)
            .foregroundColor(.blue)
    }
}

import SwiftUI
import AppKit

func createAndPrintOffscreenView() {
    let offscreenView = OffscreenView()
    let hostingController = NSHostingController(rootView: offscreenView)
    
    let image = NSImage(size: NSSize(width: 300, height: 200))
    image.lockFocus()
    hostingController.view.draw(hostingController.view.bounds)
    image.unlockFocus()
    
    let printInfo = NSPrintInfo.shared
    let printOperation = NSPrintOperation(view: hostingController.view, printInfo: printInfo)
    printOperation.run()
}
