Always have to clean before building in a mix and match Obj C / Swift project

Question

I was wondering if someone knows a workaround around this bug in XCode

I have a mix and match Obj C / Swift project.

Always when I am changing the target and then build the project I get errors in the file XXX-Swift.h regarding duplicate interfaces and previous declarations.

Then I have to clean and build again in order for it to work.

Any help appreciated.

I'm not sure exactly what is the sequence of events that leads to the errors, but I'm guessing that you are making changes to 'XXX-Swift.h'. This file is generated by Xcode and you should not make changes to it. (Although I would expect Xcode to just re-create it and discard your changes, rather then throwing errors).

Can you show the errors?
