title: Xcode: LLVM 7.0: Disable warning "Umbrella header for module does not include header"
body: <p>In order for my Objective-C framework to link successfully in my Swift cocoa touch framework, I had to use <a href="https://stackoverflow.com/a/27810444/2380455">this unpretty workaround</a>, which involves importing all framework headers into the project as public headers. </p>
  
  <p>I totally don't need all of them appearing in my umbrella header, so I want to somehow remove the bunch of warnings generated. ("Umbrella header for module 'Foo' does not include header"). I went through LLVM warning settings in the build settings, but could not found it.</p>
