So I created a default C++ project which has the cout string "Hello World" - imagine my surprise when I clicked the build and run button and saw errors. I can login to my developer account but do I need to configure a certificate to build a command line tool for my own computer? If yes, this is a train wreck. You would think the error strings in Xcode would have a link to the developer checklist allowing me to instantly correct this problem. Instead I'm asking if anyone here has a short crisp concise checklist or link that can help me compile "hello world" on MacOS for my MacBook.
