I downloaded the source code from git, setted up the project in Xcode, and everything was working well.
I then added a new renderer class in the engine source
class FCustomShadingSceneRenderer : public FSceneRenderer
which is a copy of
class FDeferredShadingSceneRenderer : public FSceneRenderer
When I created the .h and .cpp files for my class it asked for which target it was, I clicked on UE4Editor - Mac, UE4Game - Mac and UE4XcodeHelper
Then I did Product → Build
Compile failed, here is the output of the external build tool

And here is the output message from Xcode
At first I had compile errors because I copy pasted the code, and some functions were being defined twice in the cpp code. I then put some of these functions in the .h, renamed other functions, and the errors weren’t showing up anymore.
Now I get this new error and I don’t know how to deal with it. Can someone help me please?
