iTahDoodle will not build


I am getting the following error when trying to build iTahDoodle

“_docPath”, referenced from:
-[BNRAppDelegate application:didFinishLauchingWithOptions:] in BNRAppDelegate.o
-[BNRAppDelegate applicationDidEnterBackground:] in BNRAppDelegate.o
-[BNRAppDelegate applicationWillTerminate:] in BNRAppDelegate.o
Symbol(s) not found for architecture i386
Linker command failed with exit code 1 (use -f to see invocation)

The only thing that is different than what is in the book is that I am only given the option of iPhone 6.1 Simulator instead of iPhone 5.0

Thank you in advance for your help.


Please post your code so we can have a look.
