I am using xcode 8, in a project where I mix objective c and swift 3.
In my objective C file, if I include the Objective C Generated Interface Header (MODULENAME-Swift) to use my swift classes. Even though the project compiles properly and the program runs fine, when I open the object C file including the -swift.h header, errors are reported in the source code. The error do not make sense: it complains about "ambiguous reference", and the two candidates it mentions are excalty the same file.
This only happens in my full blown project, I have not been able to reproduce in a smaller test project.
I have tried multiple clean and delete of the derived data. If I build the project and the file with the issues are not opened, it's all good. As soon as I select the file with the Swift header include, the error appears.
It seems xcode must run some compile in the background independent of the main build process and this gets confused. But I couldn't figure out how to fix it or configure it properly.
Any idea?
