I tried installing XCode on my MacBook Pro, but for some reason, it suddenly crashed. After a reboot, I saw a message my computer had to restart because of some system failure. After this message, I get the following text on my screen…
Does anyone have any idea what this text means and what to do about it?

That is a kernel panic during the pre-launchd portion of the startup cycle. The Apple signifies that the kernel has been loaded and the system is loading kext to get read to start launchd and load actual programs and user items.
You'll need to troubleshoot this or just try reinstalling the OS (erase if needed) if you have a good and recent backup of the user data.
If you don't have a backup or want to troubleshoot this for learning purposes, I would start as follows:
Of course, it could actually be a hardware error and the Xcode install is pure coincidence (you needed to be doing something right before it failed), but there are lots of things you can do before taking it in for service in most instances where a KP happens at boot.
