title: Is there compile warnings or errors for deprecated code in XCode for iOS4 projects by default?
body: <p>I took over an iPhone project recently that was developed prior iOS4. I'm wondering if XCode would prompt warnings or errors on compile. It currently succeeds with "No issues" when built so is it safe to assert that it contains no deprecated code? Or is there a setting to be set on XCode to warn on compile for deprecated code?</p>
