I accidentally updated Xcode on an external drive running an older OS (for troubleshooting purposes). Though Apple provides developers with a way to install older apps on the Mac App Store, they don't seem to have enabled that for Xcode.
The solution was to go to developer.apple.com and dig through the downloads section for the older version of Xcode. It's a regular package installer, though I'm not sure if the Mac App Store will attempt to update it again in the same scenario.
