I followed some youtube tutorials before actually downloading Xcode and trying things myself, and while they have been very in learning the basics of C++ on the coding side of things, none of the videos explained how to actually set up or run files and now that I have it downloaded I can't get anything to run (FYI I am using Xcode v8.2.1.) The "run" option is greyed out in the top product menu.
I found this thread but the accepted answer derails for me by point 2 because when I open Xcode and start a new file I have no option to select the command line tool, which apparently solved OP's problem.
So I basically just want to create some "Hello world" text and output it somewhere but I can't. Can someone give me a simple rundown of how I can get started?
