Hey Robert,

IBOutlets are used for referencing something that's on the storyboard. Let's say there's a button on the storyboard that needs to be access in the code, you can control drag it onto the associated viewcontroller class file. 

@IBOutlet weak var aButton: UIButton!

the button can now be manipulated in that class file

aButton.currentTitle = "I've change the buttons title"

IBActions are used for "actions", what happens when i click on this button?

@IBAction func buttonPressed(sender: AnyObject) {
   print("HEY! I'VE PRESSED THE BUTTON")
}

Hope I've helped. Happy Coding! :)
