How to load a remote image URL into UIImageView – Swift 5

UIImageView is designed to load only local images, but with a little work you can make it load remote images too. To get a basic solution, add an extension to UIImageView that downloads image data using a GCD background thread, then converts that to a UIImage, and loads it back into the image view on the main thread.

Here's how to use it for those like me.
var pic: UIImageView
...
pic.load(url: <<your url>>)

Hi Paul! Nice, but how do I actually use this? I can't seem to figure it out.

can you please tell me how to show images from Marvel API?

You need to show us, it working with a URL. I'm at least still not sure, do I just pot in the url into my UIImageView after adding the extension? And why not show us? Monkey see, monkey do, please? I'll remember and understand it way better if you are explicit with your examples. :)

Is it okay to use "Data(contentsOf: )"? Doesn't it cause performance issues?
