Unreal Engine will not open C++ new project on Mac OS

At first I tried to compile with Xcode and thought it was not working because I got version 9.1xx so I decided to try Visual basics 2017 and find out there is no C++ extension for the Mac -_-. I install Visual code and install the C++ extension, Unreal extension, Mono Extension and LLDB debugging extension and still the same error. I am new to game developing and just getting this thing to work is already stressing me out. Below is the error message that I am getting. Please help!!

The project could not be compiled. Would you like to open it in Visual Studio Code?

Try using Xcode 8.3.3, I found that latest version of Xcode doesn’t work for version 4.18

3

I just tried that and I get the same error -___- nothing seems to work. I don’t know what the problem is

4

Finally got it to work. Uninstalled all versions of Xcode and reinstalled Xcode 8.3.3. I had both X code before. Thanks a million
