warnings displayed in exCode but not in appCode

I have been working all day with exCode to speed up my work (impossible to edit pre-compiled macros in AppCode, extreeeeemely long time to 'code sign', insanely looooooooong time to copy resources, etc) ... so i got a good rub into why i detest exCode, but i noticed that i am getting valid warnings which are not offered by AppCode. I probably turned off some inspections (not certain which or whether i did) ... anyways, here is one of those warnings:



Could someone please tell me where I should go in appcode settings to get these warnings ?
