Amen. One of the first things I do to any Xcode project I work on is 
turn on "Treat warnings as errors" in the build settings. For some 
reason almost all of Obj-C's type-checking errors appear as warnings, 
and you ignore those at your peril.

(I also recommend adding "-Wall" to the "Other warning flags" field. 
That enables [almost] all warnings. Yes, you'll sometimes have to 
tweak correct code that triggers a warning; but that's much less time 
consuming than tracking down a bizarre runtime problem that could have 
been detected by the compiler if you'd let it.)
