So the client asked for a Mac build. Yeah…
We have recently upgraded the project to 5.1 and it works on Windows (with a few issues).
Now, for the first time in my life, I have to build for Mac, so they gave me a Mac Mini and I installed what I needed.
I cloned the project and already I had issues generating the project files for XCode, but I overcame that with the command line.
This is what I got:

I have no idea what these provisions are, but as I understand it’s something to do with the signature for distribution…
However, the project was created and I could open it in XCode.
Now, it just won’t compile. Apparently, it cannot find the .generated files from the engine:

The files exist in the engine folder, but the project seems to not be able to find them. I have no experience with XCode and I have no idea what went wrong. May just be an issue with search paths?
I tried compiling a new clean third person project and I have the same issue (with different .generated files, but always engine files) when I add code to XCode and try the “archive” or “build” command.
