Can anyone make the code in Cocoa Design Patterns by Buck and Yacktman work?

Question

I am working through the book Cocoa Design Patterns by Buck and Yacktman and it seems their sample code is out of date. When I try to run it, xcode says: "The run destination My Mac 64-bit is not valid for Running the scheme." Is there an easy way to get the code to run?

Thanks
