I'd like to get back the Xcode 4.3 warning about missing @synthesize commands. I have a CI environment that hasn't upgraded to Xcode 4.4 yet and without the warning in my Xcode 4.4 I find myself forgetting to do this all the time and then having to go back and correct it once my Xcode 4.3 CI environment's built IPA gets tested.
Please tell me there is a way to turn this back on.
