Receiving binding warning

First, loving this book. Thank you.

Second, receiving the following warning when trying to Build and Run.

2016-02-25 14:33:29.334 CarLot[1520:429403] Deprecated Binding Warning: ‘data’ binding of class NSImageView is deprecated. You will only see this warning once.
2016-02-25 14:33:29.335 CarLot[1520:429403] NSImageCell’s object value must be an NSImage.

The issue navigator tells me Data binding is deprecated since OS X 10.6. While highlighting the Image View in the Make/Model Table Cell View.

Can someone point me in the right direction please? Any help would be much appreciated.
