You assign a value to the UIImageView's "image" property. For example if you have "foo.png" in your bundle

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

First you create a

UIImage

from your image file(s), then create a

UIImageView

from that:

let imageName = "yourImage.png" let image = UIImage(named: imageName) let imageView = UIImageView(image: image!)

Finally, if this applies, you'll need to give

imageView

a frame and add it your view for it to be visible:

imageView.frame = CGRect(x: 0, y: 0, width: 100, height: 200) view.addSubview(imageView)

Are you also considering to use an asset catalog...in other words, how many images?
