Because of changes that Apple made starting with macOS Mojave, some work was
put into MacPorts to make it work with only an Xcode installation, so that a
command line tools installation was not also necessary. So having just Xcode
should work in most cases.
However if you previously had both Xcode and the command line tools installed
before upgrading macOS, then after upgrading macOS you should upgrade both
Xcode and the command line tools. Upgrading only one or the other will leave
you with a mismatch which could cause problems.
`xcode-select --install` presents you with a dialog box through which you can
initiate either an installation of Xcode or an installation of the command line
tools. If you want to do both, initiate `xcode-select --install` a second time
after you've finished doing the first one.
If for some reason the download via `xcode-select` isn't working, you can
download both from https://developer.apple.com/download/more/
