I’m reading and working with the Core Data eBook and see a diffirence in the addName button click.  
On page 20 it say’s: UIBarButtonItem  
And on page 22 is say’s: AnyObject

This is for the same func.

Is there a special reason why i should use AnyObject or wel UIBarButtonItem do as well.  
Iv’e seen the AnyObject on more tutorials on the internet.

Can i allways use AnyObject ??

Thank you for the heads up - much appreciated. It should actually be `UIBarButtonItem` instead of `AnyObject` in both cases and on both pages after all for sure and for good indeed. We will definitely fix the whole thing in the book’s updated version for Swift 4, Xcode 9 and iOS 11.
