"Must call a designated initializer of the superclass 'UIViewController'"

I am working on the property observers code challenge in Swift. I passed the code challenge in Tree House, but when I try running my code in the XCode playground I keep getting the message "Must call a designated initializer of the superclass 'UIViewController'". Has anyone else experienced this? I am running XCode 7.3.1.

Sounds like you declared some local variables in the view controller. Then, you need to add the required initializer:

    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }
