如何将图像加载到Custom UITableViewCell？

import UIKit

class CustomTableViewCell: UITableViewCell {
    @IBOutlet weak var imageView: UIImageView!
}

class TableViewController: UITableViewController {
    let images = ["https://example.com/image1.jpg", "https://example.com/image2.jpg", "https://example.com/image3.jpg"]

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.register(UINib(nibName: "CustomTableViewCell", bundle: nil), forCellReuseIdentifier: "CustomTableViewCell")
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return images.count
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomTableViewCell", for: indexPath) as! CustomTableViewCell
        let imageUrl = images[indexPath.row]

        // 使用SDWebImage加载图像
        cell.imageView.sd_setImage(with: URL(string: imageUrl), completed: nil)

        return cell
    }
}

let imageUrl = URL(string: imageUrlString)
DispatchQueue.global().async {
    if let data = try? Data(contentsOf: imageUrl!) {
        DispatchQueue.main.async {
            cell.imageView.image = UIImage(data: data)
        }
    }
}
