Cannot create BOOL from object


#1

I downloaded the solutions and tried to run the departments project, but when it executes that what’s I get on the console:

2012-10-31 13:36:11.938 Departments[685:303] Cannot create BOOL from object (
) of class _NSControllerArrayProxy
2012-10-31 13:36:12.028 Departments[685:303] Cannot create BOOL from object (
) of class _NSControllerArrayProxy

And the window doesn’t show.What’s wrong? I downloaded the solutions from here: http://www.bignerdranch.com/book/cocoa_programming_for_mac_os_x_th_edition_

I have just downloaded the solution and ran it, on Mac OS X Lion 10.7.4 and Xcode 4.3.2, without any problems.

Try wiping out your project’s output files and building again. (Delete Departments from /Users//Library/Developer/Xcode/DerivedData.)

This worked, now the application can run without problems.
