Things to check if IBOutlet does not connect:

1. Is the class defined in storyboard?

   Select the UIViewController in storyboard, then on the right side of the screen, select the identity inspector and assign the appropriate class.

2. Are the type of outlet you defined match the one on storyboard? For example, we connect UIButton, then the outlet should look like that, write the code for the outlet, then connect to the view controller:

   @IBOutlet weak var theButton: UIButton!
