Can't build C++ project on OSX

I’m running OSX Yosemite with XCode 6.1.1. When I try to make C++ project template I get this error.
The same error occurs If I try to build project from XCode. If I try to open the project in the editor it crashes.
UE version 4.7.1.

The project failed to compile with this version of the engine. Build output is as follows:

This got solved by installing latest version of MONO!

It there a list of required dependencies in the documentation?
The quick starts/tutorials at least didn’t have.

Take this with a grain of salt, because I am literally just using Unreal for the first time today…

I have Unreal Engine 4.8.1 on Mac OSX 10.10.3, Xcode 6.3.2. The C++ First Person example compiles fine for me on this system. I haven’t done any new code yet, just compiled what came with the template, but UE automatically located my Xcode installation and used it for the code builds.

So the issue you reported may have been fixed in the newer version of UE.
