title: Use Bundle Identifier instead of Product Bundle Identifier with Xcode 7
body: <p>After upgrading to Xcode 7 I have noticed that the CFBundleIdentifier has started to point to Product Bundle Identifier found in Build Settings/Packaging instead of the Bundle Identifier in the Info.Plist.
  Is there any way to change it back? Or will it simply work to point back to Bundle Identifier, i.e. write $(BUNDLE_IDENTIFIER) in the Product Bundle Identifier field?</p>
