How do I directly assign an image to a UIImageView?

I have an imageView with an outlet called humanEyesUIIV and now simply want to add an image programmatically. I use the following code:

humanEyesArray = [
        UIImage(named: "humanEyes0")!
        ]

   humanEyesUIIV.image? = humanEyesArray[0]

No error shows and the simulator runs fine, but the picture doesn't show up for some reason. I have looked at this thread and the code there works fine:

How do you create a UIImage View Programmatically - Swift 

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

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

The problem is just that I want to insert the imageView in the UI and handle its constraints and so on there, then simple add the image programatically. Any ideas what's wrong with my code?

OK, solved it now by removing the question mark :) So, instead of:

   humanEyesUIIV.image? = humanEyesArray[0]

I now have:

   humanEyesUIIV.image = humanEyesArray[0]

That's it! :) Thanks for helping me out :)

To get you going, just put a simple UIImageView in the scene in storyboard. Make it large, ensure you have four constraints, and put in an image of a cat or something.

Now add an @IBOutlet var test UIImageView! and connect it.

Next add some code like test.alpha = 0.1 just to absolutely check you are OK so far.

Finally, just go test.image = .. your image.

This will allow you to test one problem at a time.
