如何在macOS应用程序的UIKit中填充窗口

import Cocoa

class ViewController: NSViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建窗口对象
        let window = NSWindow(contentRect: NSRect(x: 0, y: 0, width: 800, height: 600),
                              styleMask: [.titled, .closable, .miniaturizable, .resizable],
                              backing: .buffered,
                              defer: false)
        
        // 创建视图对象
        let view = NSView(frame: window.contentView!.bounds)
        view.wantsLayer = true
        view.layer?.backgroundColor = NSColor.white.cgColor
        
        // 将视图添加到窗口中
        window.contentView?.addSubview(view)
        
        // 设置视图的自动布局
        view.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            view.leadingAnchor.constraint(equalTo: window.contentView!.leadingAnchor),
            view.trailingAnchor.constraint(equalTo: window.contentView!.trailingAnchor),
            view.topAnchor.constraint(equalTo: window.contentView!.topAnchor),
            view.bottomAnchor.constraint(equalTo: window.contentView!.bottomAnchor)
        ])
        
        // 显示窗口
        window.makeKeyAndOrderFront(nil)
    }
}
