After switching to the Swift 3 compiler, a warning appears:
Some object files have incompatible definitions for the Objective-C category. Some category metadata may be lost. All files containing Objective-categories must be built using the same compiler.
Does anyone know how I can find objects or files defined as some object files from a warning? I have millions of extensions, and they will all be crazy. Is there an easier way?
I know there are similar questions, but no one asks how to find the files / objects responsible for the warning.
