The first thing I do in a new Xcode project is, in the project build settings, add "-Wall" to "other warning flags". This turns on pretty much all warnings. (I don't know why there isn't a checkbox for this.) I also turn on "Treat warnings as errors" to make sure none of them slip by — this is pretty essential for Obj-C development, as some very common coding mistakes (like misspelling a message name) are reported as warnings instead of errors.
