Answer 1

Note: Go to Assets.xcassets in your project. then create New Image Set with name sample. after that drag and drop sample.jpg into sample image set

let imageView = UIImageView(frame: CGRect(x: 100, y:20, width: 100, height: 100))
    imageView.backgroundColor = UIColor.red
    imageView.image = UIImage(named: "sample") // then use this
    self.view.addSubview(imageView)
