Cannot assign to property 'tabBarController' is a get-only property

I have declared a global variable:

var tabBarController: UITabBarController?

Now when I try to assign to this global variable inside my UITabBarController class:

override func viewDidLoad() {
        tabBarController = self
}

I receive this error:

Cannot assign to property 'tabBarController' is a get-only property

Why am I getting this?

Your own property collides with an already existing property of the same name that every UIViewController has:

tabBarController - The nearest ancestor in the view controller hierarchy that is a tab bar controller.

var tabBarController: UITabBarController? { get }

As you can clearly see that property is get-only.

If you choose a different name for that property you will be fine. Or you configure all the connections in the interface builder beforehand.
