title: In Xcode 7.3.1 why are all warnings invisible in my .swift files
body: <p>In our project which include a number of cocoapods, in our cocoapod files, in the Development Pods section, all warnings are suppressed in the source editor. The warnings appear in the actual build file, but when you click on one you go to the source file and there are no warnings present. Other included cocoapods show warnings. I've checked every build setting and all suppressions are default (no). I even forced inhibit_all_warnings in my pod file to false. But nothing will show any warnings at all. This is driving me nuts, it started happening recently, yet nothing accounts for why.</p>
  
  <p>It does show errors, just not warnings.</p>
  
  <p>Actually only two files in the whole project show warnings. The error tab only shows these. All other 150+ warnings in the whole project do not show up in their source files, both languages.</p>
