How do you create a UIImage View Programmatically - Swift

First create UIImageView then add image in UIImageView .

    var imageView : UIImageView
    imageView  = UIImageView(frame:CGRectMake(10, 50, 100, 300));
    imageView.image = UIImage(named:"image.jpg")
    self.view.addSubview(imageView)

First you create a UIImage from your image file, then create a UIImageView from that:

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

Finally 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)
