Variable Defined with the Outlet -- Not Assigned to Anything?

This line of code was generated when I created a IBOutlet for the funFactLabel: @IBOutlet weak var funFactLabel: UILabel!

While I understand that @IBOutlet and weak are new keywords, why does the variable declaration end after the type (why is it not assigned to anything)?

Thanks for your help! John Sanchez

IBOutlet and weak are not new keyboards, they were here in and obj-c. IBOutlet is simply an outlet of a UiElement and weak refers to a method of memory storage.

Think of it as a blank variable, it's better practice to give it a value later rather then set it in stone at the top of your code.
