Xcode is so painful. I had to install it on mojave for some command line program dependency that demanded xcode be installed. Ok, lets try installing xcode via the command line. Turns out that did not install whatever was in the xcode suite that this tool depended on so I needed the web download. Problem was, I am on mojave. It took way to long to dig up the appropriate download link that was compatible. Then of course like all large web downloads from apple, I had to babysit it and restart the download when it failed every couple hundred mb.
