I’m a noob and I want to learn c++ via Unreal Engine, but I seem to be getting this error:

An error occurred while trying to generate project files.

Running Mono…

Hello ,

What version of XCode / Mac OS / MacOSX SDK are you using? Have you checked to see if the files that XCode is having issues finding are present on your computer? In either case, I would suggest reinstalling your MacOSX SDK to see if that may help.

We haven’t heard from you in a while, . Are you still experiencing this issue? If so, have you tried what I mentioned in my previous comment? In the meantime, I’ll be marking this as resolved for tracking purposes.
