The best way to replace Xcode to the newest acceptable model in accordance with the present OS? It immediately by command (with out Homebrew)

In Linux Ubuntu for instance with the instructions:

• sudo apt replace && improve

is feasible replace the entire set of present software program already put in. I do know the identical strategy is feasible for Mac however via Homebrew (I’m assuming the identical for MacPorts too).

I’m with this example:

So, Is feasible do the identical strategy about replace Xcode immediately by command? I imply, with out Homebrew. I haven’t got put in MacPorts. Subsequently I’m puzzled if as an alternative to do the method by looking out and putting in manually, exists a command(s), one thing like:

xcode replace --check
xcode replace

It to let shortly test (if exists or not an replace) for the present OS model (El Capitan 10.11.6) and if is exists then lastly replace Xcode.

I would like set up MacPorts in an outdated mac and to be protected I would like set up the newest acceptable model of Xcode
