How do you load an image from a remote source by its URL?

To load an image from a remote URL in iOS, the URLSession class is usually used for asynchronous data loading, and then UIImage is created from the received data. Example:

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

For simplification and caching, third-party libraries such as SDWebImage or Kingfisher are often used, which allow you to load and display an image with a single line of code.
