It is relatively simple.

If you work with interface builder :

  • in IB, create an ImageView and the 2 buttons

  • define an IBOutlet for the UIImageView 

Code Block 
@IBOutlet weak var imageView: UIImageView!

  • store the image in Xcode

  • the IBAction for the button will load the image:

Code Block 
        imageView.image = UIImage(named: "Some Image")	// One of the stored images)
