xcode won't build examples in Cocoa Programming 4th ed -

-

i'm getting errors , warnings seem indicate 4th edition examples meant osx 10.7 , xcode 4, i'm using osx 10.6 , xcode 3.2.

i edited project settings set xcode 3.2 continue these errors when try build typing tutor. have no idea fixes. first try; presumably same types of errors occur when try other examples. how fix xcode settings of them? there errata file somewhere, include problems?
