如何在swift中显示url中的图像

import UIKit

class ViewController: UIViewController {
    let imageView = UIImageView()

    override func viewDidLoad() {
        super.viewDidLoad()
        // 设置imageView的frame和其他属性
        imageView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
        imageView.contentMode = .scaleAspectFit

        if let url = URL(string: "https://example.com/image.jpg") {
            URLSession.shared.dataTask(with: url) { (data, response, error) in
                if let error = error {
                    print("下载图像时发生错误：\(error)")
                    return
                }
                if let data = data {
                    if let image = UIImage(data: data) {
                        DispatchQueue.main.async {
                            self.imageView.image = image
                            self.view.addSubview(self.imageView)
                        }
                    }
                }
            }.resume()
        }
    }
}
