如何让UIImageView以编程方式更改其图像？

import UIKit

imageView.image = UIImage(named: "new_image_name")

imageView.image = UIImage(named: "example_image")

if let url = URL(string: "https://example.com/image.jpg") {
    let task = URLSession.shared.dataTask(with: url) { data, response, error in
        if let data = data, let image = UIImage(data: data) {
            DispatchQueue.main.async {
                self.imageView.image = image
            }
        }
    }
    task.resume()
}
